How long do mower batteries last

Corrosion occurs in the presence of dissimilar metals, sulfuric acid, electricity and water. The byproducts of corrosion, anhydrous copper sulfate and lead sulfate, are also great insulators. Fortunately, a wire brush and some baking soda solution can neutralize battery acid and eliminate resistance. Pitting in the starter relay is also common, created when the sudden circuit break arcs and burns away the contacts.

With enough pitting, the flow of electricity to the starter motor could completely stop. Depending on the setup, you might be able to bypass the relay or solenoid to get the engine started.

Of course, everything else being in good condition, the battery could be weak or dead, which could cause any of these symptoms. You might be able to revive it with a charger, but the damage might already be irreversible if the voltage is less than 7. The best way to help the battery last longer is to keep everything clean and dry and protect the battery terminals from corrosion during the mowing season. Consider using a 12V float charger to keep it in optimum condition for the next season. In general, owners of lithium-ion powered lawnmowers can expect charge cycles or years of operation.

It is now crucial to understand the answer to this question will inevitably vary as it is based on a multitude of factors, including the types of mowers. So, keep reading to learn pertinent facts about the predominant kinds of lawnmowers and their battery lifespans.

Long gone are the days of riding mowers using pull-cord-style recoil starters. Most of the bigger riding mowers these days have a battery for starting up. Many even come equipped with basic alternators and voltage regulators to work as a functional charging system that keeps the battery juiced up. However, there are some definite similarities. For starters, many lawn mower batteries use cells that have lead plates that are submerged inside an acid electrolyte.

As the battery discharges, these plates get covered with sulfate, meaning the acid turns alkaline. As it is charged back up again, the plate sulfates return to the acid electrolyte, turning acidic once more. In both mower and car batteries, the antimony and acid content of a battery can eventually result in corrosion issues. The lead-acid battery design used in many mowers and quite a few passenger vehicles is a technology roughly a century old. However, not all mowers use these kinds of batteries, so their lifespan varies.

However, the lifespan of the batteries is a common concern, since replacement batteries are added expenses that usually surprise you.

As a result, it will give consistent voltage with time. It has 2 volts in each cell. Most of the push mowers are pull-started. However, some push mowers and most riding ones are electric-started. This is made easier with the use of a lawn mower battery. The batter, however, has a lifespan, and at one point, you will have to replace it. You may be used to the automatic batteries, which regardless of the make have fixed terminals.

However, note that lawn mower batteries differ. Thus, if your red positive terminal appears to the left corner, it is recommeneded that you buy a U1L battery. This positioning may not be essential for the battery charger, but it is essential when it comes to connecting with the electrical system. The wires must be relaxed; otherwise, your mower will start developing electrical problems. The coursing in a mowers battery is crucial in the starting of the engine.

Before you buy a battery, ensure to check its cold cranking amp CCA. Ensure that it is up to par or more than the specifications of your mower.

This way, your engine will start immediately with no downtime. It would be better to pay the extra coins for the right CCA. At least all battery mowers come with their specific chargers and manual for use.

There is so much contradictory information out there, as to whether you should let the battery drain completely before recharging it. For lithium ion batteries, as already mentioned, letting the battery run out completely or overcharge will significantly reduce its lifespan.

You may be wondering whether there is anything to be done to extend the battery life of your lawn mower in between charging intervals.
