Caring for Your Generator’s Battery

EB2800iElectric start is one of the best features you can have on a generator, letting you turn a key whenever you need power. However, that starter won’t work if you aren’t keeping up with the maintenance on your generator’s battery. Here’s what you need to know about keeping your generator ready to start the next time you have a power outage, go on camping trip or work in a remote area.

Does My Generator Have a Battery?

The battery is only used to power the generator’s electric starter and has no connection to the unit’s AC power generation system. If your model doesn’t have an electric starter, it doesn’t have a battery.

These current models have electric start, and thus have a battery:
EU3000iS
EM4000S
EB5000
EM5000S
EB6500
EM6500S
EU7000i
EB10000

Honda doesn’t list battery maintenance as part of the regular maintenance schedule, but it’s a good idea to clean the connections at least every 6 months or 100 hours of use. Honda also recommends recharging the battery monthly if the generator isn’t in frequent service.

Battery Handling Safety

Battery components contain lead. Always wash your hands after handling the battery or terminals.

If you spill this acid onto yourself, contact medical personnel immediately and do the following to limit the damage the acid can do to your body:

Eye contact — Flush the eye with water from a cup or container for 15 minutes. Do not use water under pressure, including water directly from a faucet, as this can cause eye damage.

Skin contact — Remove any clothing that came in contact with the acid. Flush the affected area with large quantities of water.

Swallowing — Drink water or milk. Do not induce vomiting.

Accessing the Battery

Current EM series generators store the battery behind a cover directly below the outlets, while earlier open frame generators place the battery behind a metal grid next to the engine. To access the battery on EU Series generators, the entire front panel must be removed.

Once you can access the battery, remove the negative battery terminal first, followed by the positive terminal.

Smaller batteries used in enclosed units have a band that can be unclipped to remove the battery. Larger batteries are held on by a set plate. To remove this plate, loosen the flange nuts on the ends of the plate. Pull the plate off of the battery and slide the battery and battery tray out of the generator.

Battery Electrolyte

The electrolyte level needs to stay between the upper and lower marks on the battery cells. If the level dips below the lower mark, the battery can sulfate, losing the ability to store electrical power.

The lower and upper-level marks are marked on the outside of the battery directly below the terminals. If one of the cells is low, carefully pry up the battery cell caps located next to the terminals. Add distilled water to the cell, then reinstall the cap.

If the battery seems to lose electrolyte rapidly, or the battery is weak despite following maintenance guidelines, have your generator inspected by a dealer. It could be an indication of a dying battery or a faulty charging system.

Cleaning

Any corrosion on the battery or terminals should be cleaned off with a brush and a mix of baking soda and water. This basic solution will neutralize the acid that has collected on these components.

Charging

Charge the battery at 10% of its amp hour rating for three to four hours. It’s common for replacement batteries to have different specifications from the ones originally installed in Honda’s generators. When setting the charge rate, go by the Ah rating printed on top of the battery, not the specifications in your owner’s manual.

Generator Safety

Honda generator

A generator makes remote work easier, gives you more options when camping and be a lifesaver when you lose grid power. However, if they aren’t used correctly, they can be dangerous: the CDC estimates around 70 people die each year due to generator misuse. With a little preparation, you can set up your Honda generator to provide the power you need without the risk.

Carbon Monoxide

Dozens of people die each year from carbon monoxide poisoning caused by using a generator.
This odorless gas fills up the spaces on red blood cells that normally carry oxygen, causing asphyxiation. These deaths are caused by using the generator inside or too close to a house. If the engine is inside a garage, the exhaust gases can collect, building up lethal levels of CO.

Why does this happen? Partly it’s because people don’t realize the danger, and partly because they don’t plan ahead to use their generator outdoors. If you’re getting your first generator when you face a major power outage, this probably isn’t going to cross your mind. When you buy a generator, you also need to buy the extension cables needed to get the power where you need it while still keeping the generator in a safe place.

To be safe, the generator should be at least 20 feet away from doors, windows and vents. Plan accordingly, pairing the generator with cords that will carry current into the house where you need it.

Picking the Right Cables

The extension cables you use with your generator should be able to carry the maximum current rated for the outlet, be rated for outdoor use, and the insulator on extension cables should be made out of TPE. Product labeling can be confusing, but you can find the information you need printed on the cable itself. If you see the letters “S,” “E” and either “W” or “W-A,” it meets these requirements. If you see an “O” or “OO,” the cable is also oil resistant, which is good if the cable will be running through a garage.

The wire itself should be thick enough to handle high current loads. Look for “AWG” on the cord followed by a number. This is the wire gauge. A 14 or 12 gauge wire can handle 10-15 amp loads, while 10 gauge can handle loads over 15 amps.

GFCI and Shock Prevention

Most 120-volt duplex outlets on Honda generators come with a Ground Fault Circuit Interrupter (GFCI). This device cuts the circuit if a fault is detected, which can happen if there is a short caused by a failing appliance or a damaged cable. Test the outlet before each use by pushing in the “Test” button. If the reset button pops out, the GFCI is working. Push the reset button to re-enable the outlet. If the red light next to the outlet is blinking, the GFCI has failed and needs to be repaired before the outlet is used.

Protecting the People Restoring Your Power

While you may be safe from electrocution, improper installation can put line workers in danger. If you have your generator wired into your home electrical system, you are legally required to have a professionally-installed transfer switch. This device cuts off the house wiring from the grid, preventing electricity from your generator from reaching outside lines. Without it, a worker could pick up what should be a dead line and be electrocuted.

Fires

Running out of fuel in a mower is a good excuse to take a break, but if you’re using a generator for emergency power, you probably want to keep the engine running. If you have a small spill onto a hot or running engine, the resulting fire could put you in the emergency room. Even enclosed generators can have fires as the result of spilled gas dripping between the maintenance covers or onto the tailpipe.

When it’s time to add more gas, shut off the generator and let the engine cool for 15 minutes. This reduces the chance of starting a fire if fuel drips onto the engine or exhaust.

Move the generator 10 feet away from where you were using it before refilling. Once the tank is full, move it back to where it was. This prevents leftover fumes from igniting when you restart the engine.

Changing the Oil on Your Generator

Honda Generator

Changing oil in a small engine is usually straightforward, but generators have some quirks due to their design and the way they’re used. Here’s what you need to know from getting oil out of an engine that has no obvious drain plug to ensuring proper break-in on a device that can go unused for months at a time.

Checking the Oil

It’s possible for oil to burn or leak during operation, especially on engines that have seen a lot of hours of use. Always check the oil before each use, and each time you need to fill the tank. Most generator engines come with Honda’s Oil Alert system, which will shut down the engine if the oil level is too low to protect the motor from damage; being proactive about topping up the oil will prevent unexpected shutdowns.

To get the correct reading when checking the oil, remove the dipstick/filler cap, wipe it off and insert it back into the filler neck without screwing or pushing it in.

When to Change the Oil

On most models, Honda recommends changing the oil after the first month or 20 hours of use, then every 6 months or 100 hours thereafter. You should always replace the oil in the first month, but it’s a good idea to replace the oil after 20 hours of use, even if it has already been changed. That short interval is there to ensure any metal particles left over from break-in don’t stay in the engine where they could cause premature wear.

After the break-in, it’s important to change the oil after the specified time, even if it hasn’t been used. This removes water and other contaminants that may have migrated into the oil during storage.

Draining the Oil on Small Portable Generators

On some models like the EU 2000, the engine doesn’t have a drain plug and the entire unit is surrounded by a case to reduce noise. Once the maintenance panel has been removed to access the engine, the dipstick can be removed and the entire generator tilted so that the oil flows out of the filler neck. This neck has a lip that will pour the oil onto a tab on the cover and then into your oil pan. If you’re having trouble positioning the generator for drainage, a marine oil change pump can be used to transfer the used oil from the crankcase to a suitable container.

Draining the Oil on Frame-mounted Generators

Unlike smaller units, these generators leave the engine fully exposed. The drain plug is located at the base of the engine next to the dipstick, and the frame will clear the drainage area, so the generator does not need to be tilted. Instead, set the generator on a support such as a set of bricks or blocks of wood to lift it off of the ground and slide the oil pan underneath the engine to catch the oil.

Filling the Crankcase

Honda’s engines are designed to be filled while level with the oil coming up to the edge of the filler neck. A funnel will be needed to fill engines that don’t have a drain plug.

Recommended Oil

While Honda Power Equipment oil is the best choice, the engine used in your generator is designed to use multi-weight engine oil, just like your car, making lubricants readily available. 10W30 is recommended for current engines in most conditions, while 5W30 can be used in extreme cold and SAE 30 can be used in warmer temperatures; check your engine owner’s manual for specific temperature recommendations. This oil should at least meet SAE’s SJ standard, which should be true of any oil purchased in the last couple years.

Plugging into a Honda Generator

Honda generatorA Honda generator can keep your tools and appliances running whether you’re tailgating, waiting for a storm to pass or working in remote areas, but only if you have a way to get power from the outlets to your equipment. What should you look for when getting cables to use with your generator?

Why are Extension Cables Necessary?

The engine in your generator produces an odorless gas called “carbon monoxide.” If it’s run indoors or next to a building, this gas can collect in concentrations that can lead to asphyxiation. Over 85% of non-fire related deaths caused by carbon monoxide poisoning in the U.S. are the result of generators being used indoors. To keep the generator in an open area and still have access to the power it produces, you need extension cables.

While you may have some cables on hand, you likely don’t have ones that can withstand the high currents and conditions needed to safely get the most power from your generator to what you want to power. Buying the right cables now will let you put your generator to work as needed to provide power during blackouts and in remote locations.

Plug Types

Small portable generators have duplex plugs, while larger generators have both duplex and twist lock plugs.

A duplex plug has two 120 volt sockets connected to the circuit by a single set of wires. This means the rated amperage applies to the total draw from both sockets on a duplex plug. When selecting cables, one cable can be used to transfer the full rated power of the duplex plug to the location you need the electricity, leaving the other socket unused. Honda uses Ground Fault Circuit Interrupter (GFCI) three pronged sockets for these plugs, which have breakers that cut the flow of electricity if there’s a short.

A twist lock plug has curved blades that are designed to slide into the socket and twist, locking the plug in place so it remains secure when subject to movement and vibration. It can be used with a transfer switch or with an extension cable that splits the current into standard 120-volt sockets.

Transfer Switches

To legally connect your generator directly to your household’s wiring system, it needs to be plugged into a professionally-installed transfer switch. This device breaks the connection between your house and the electrical grid when the generator is active to keep power from being sent into neighboring power lines where it could electrocute line workers.

The switch will have its own twist lock plug, requiring a female to female twist lock cable to make the connection. Finding the right cable is easy since this socket combination is almost exclusively for transferring power between these two devices: just look for one that matches the maximum amp rating on your generator that has plugs that match both the generator’s outlet and the transfer switch’s plug.

Finding the Right Cord

The meaning of product terms like “outdoor” and “heavy duty” can vary, but you can find out exactly what an extension cord is capable of thanks to standard cable labeling that can be found printed on the cord jacket and in the cable’s specifications. This starts with a series of letters that describe the construction of the cord:

S – Flexible, general use cord
W – Outdoor use
J – “Junior service” insulation rated at 300 watts. Wire without this designation is rated at 600 watts.
P – Parallel wire construction for household use
T – Vinyl thermoplastic jacket
E – Thermoplastic elastomer rubber (TPE) jacket
O – Oil Resistant
OO – Oil resistant jacket and insulation
W, W-A – Weather approved for indoor/outdoor use
HPN – Oil resistant for portable and damp location use
SPT-2, SPT-3 – For light duty damp locations

For example, an SWPEO cable is a general use cord designed for outdoor use with parallel wire construction and a TPE outer jacket that is oil resistant. In general, cords should use TPE for durability, be weather and water resistant, and, if you’ll use it near oil-lubricated equipment like trucks and tractors, be oil resistant.

Next on the label are the letters “AWG” followed by a dash and two numbers separated by a “/.” The first number is the American Wire Gauge number. A lower number indicates a thicker, less resistive cable. Your needs will vary, but there are some general guidelines for wire thickness:

16 gauge – under 10 amps
14 gauge – 10-15 amps at up to 50 feet
12 gauge – 10-15 amps at up to 100 feet
10 gauge – 15 amps or more

The number after the “/” is the number of conductors, usually three to support a three prong plug and outlet. For example, “AWG 10/3” means the extension cable uses 10 gauge wiring with three conductors.

How to change the oil of a Honda EU2000i Generator

Honda EU2000i

After you have purchased your new Honda EU2000i Generator it is important that you keep track of the regular maintenance needs of your equipment to ensure that it does not get damaged during operation. Part of this maintenance is regular oil changes. You should be checking the engine oil each time you use the generator to make sure there is enough oil in it, especially if it has been sitting for an extended period of time. Otherwise, your first oil change should happen at the end of your first month, or the first 20 hours of operation. Each additional oil change will take place at 6-months or 100 operating hour intervals afterwards. This is a very simple process that should only take a few minutes and a single screwdriver along with an oil pan and funnel.
