5 Highest CCA Lawn Mower Batteries (2021)

Only a few things can be more disappointing than being unable to start your lawn mower when you’re fully ready to do some lawn trimming. When that happens, the battery is the usual culprit.

But many times, it’s not because your battery is dead. It’s because the battery isn’t just strong enough to get the engine to start. And that’s why you shouldn’t skimp on cold-cranking amps (CCA) when buying a battery for your lawnmower.

With a low CCA battery, you’d have a hard time starting your lawn mower’s engine during the winter months. So, the only way to avoid this mess is to settle for a high-CCA lawn mower battery that can easily start your engine at any time of the year.

In this post, we’d be looking at some of the highest CCA lawn mower batteries on the market.

How long do lawnmower batteries last?

On average, lawn mower batteries last for up to 2-3 years but the way you store and take care of them also affects their longevity. With proper care and maintenance, the battery may last longer than three years.

Why does my lawn mower battery keep dying?

If your lawn mower battery keeps dying fast, the most probable cause is leaving the battery idle for too long, especially during dry seasons. Another reason could be corrosion as that means that the inside of the battery is leaking out. Sometimes, it could be that the sulfur molecules are emitted from the battery’s electrolyte solution and latch to the battery’s plates. Other culprits are bent interlock or damaged wiring.

Signs that you need a new lawn mower battery

Even with proper maintenance and charging, lawn mower batteries will eventually deplete and fail to hold further charges. They will hit the end of their lifespan and you need to know when they are giving those clues so you can invest in a new one in good time. Here are some signs to watch out for.

Slow starting

Generally, lawn mower batteries have enough power to start fast regardless of the weather conditions. If you notice that you have to try a couple of times before the battery starts, it may be a sign that the battery is losing reliability. You should have the battery tested so you can rule out all other causes of slow starting.

Quick charge loss

Another common sign that your lawn mower battery needs a replacement is when it fails to hold charge. This typically happens after a long period of usage, hinting that the internal components of the battery are beginning to wear out.

Corroded terminals

When a battery’s terminal gets corroded, it loses some material and this affects the contact between the terminals and the connectors. Corroded terminals can be caused by either poor maintenance (not cleaning the terminals properly) or due to usage. When the terminals are eaten up, you will need a new battery.

Cracked case

Lawn mower batteries come in a durable housing that is capable of withstanding physical abuse. But if upon inspection, you find a crack on the battery, it means there’s a good chance that there will be leakage of electrolyte in no time.

Wear and tear

Lastly, lawn mower batteries need a replacement when the materials used for their construction have thinned out and are looking old. Rather than wait for the battery to malfunction, it’s a smart move to get a replacement to avoid headaches later.
