Know-How Notes – Six Lawn Mower Battery Tips

The sun is out, the grass has begun to green up and grow once again. Unlike last year, you are determined to get the yard under control early this year. You hop on the ol’ lawn tractor and spin the key. Nothing. Not a click, not whir, and certainly no fire. You forgot to pull the battery last fall and now your lawn mower is out of commission. Even if you are meticulous about winterizing your gardening equipment, the batteries only last so long.

The average life of a lawn & garden battery is three years. You can stretch the useful life of your battery with these six lawn mower battery tips:

#1 Charge!

All lawn & garden batteries are flooded lead-acid batteries. That means that they need a regular charge cycle, otherwise they start to crystallize and lose their ability to stay charged. A maintenance charger will keep your battery fresh while it is in storage.

If the battery has been drained to this point, then chances are, it is shot. It might be revived with a good charge, but it will definitely be on its way out.

#2 Keep It Clean

Corroded terminals are a guaranteed way to ensure frustration on mow day. Heavy corrosion can be cleaned with a wire brush or terminal cleaner. To prevent corrosion build up, the terminals should be sealed with anti-corrosion gel.

Corrosion happens anytime you have differential metals, moisture and air. These terminals are in really bad shape.

#3 Fill ‘Er Up

Some lawn & garden batteries require maintenance, which is to say that the water inside the battery needs to be checked and filled regularly. If your battery has removable caps, then you need to check the water level and when necessary, fill with distilled water.

 

#4 One Size Does NOT Fit All

Just like cars, there is a right battery for your application. Lawn & garden equipment use both 6- and 12-volt batteries, make sure that the battery you need is the right one for your equipment.

If that new battery is too big to fit in the compartment, it won't work very well. Make sure you note the battery model before going to buy the new battery.

#5 Righty-Tighty

Loose terminal connections can mimic a faulty battery. Not only that, but also lead to low charge rates and corroded terminals and wires. Check the terminals on a regular basis to make sure they are tight.

It is a good idea to replace the fasteners for your battery cables when changing the battery. If the bolts strip out, you could lose connection, which can mimic a faulty battery.

#6 Wireless Mower?

Wi-Fi doesn’t work on lawn mowers, you need a solid connection to the battery and starter in order for it all to work. If the wires are corroded, burned, or frayed, then the starter is not getting the current it needs to function and the battery is not getting what it needs to stay charged. Always change power leads when they are frayed or burned.

    I am a new widow and now teaching myself lawn mower repair. The article had several points that were helpful to me. I was given a non-working John Deere JS30 that I am trying to bring back from the dead by performing maintenance, replacing the gas line and the carburetor since it was full of gum and varnish (I’m learning new terms) when I started tearing into the mower. My simple question is, When replacing the original push mower battery (SW4L-BS) what do the letters at the beginning of the battery part number or description mean? Is it related to the type of the battery or possibly the brand name and is it important that it be identical when replacing or more of the volt and amp information of importance? Salesmen just say, buy a (4L-BS) and you’re fine, but the owner’s manual is very specific about the battery description. The battery in the mower had no label or markings whatsoever to identify it, nor had it ever been removed previously. So, what part of the battery part number is important when replacing?
