Can I use a higher CCA battery in my lawn mower?
Choosing a mower battery with too low a CCA might not start the engine at all, or, if it can start the engine, it may overtax the battery's own construction and wear it out faster. On the other hand, a battery with a higher CCA will have no problems starting a smaller engine, but it won't provide any added benefits.

Why is it harder to cut grass with a mower?
With mowers the internal components and the blade spinning at full RPM under zero load all contribute to form resistance… but cutting the grass will make it harder for the mower to turn the blade at the correct speed so the resistance is higher when under use or load. To maintain blade speed the mower has to overcome more resistance and thus draws more current.

What is a CCA rating on a mower battery?
A CCA rating is a measure of how much current the battery can deliver for 30 seconds at 0 degrees Fahrenheit. It's probably not too likely that you'll be running your mower in zero-degree weather (unless it's a snow blower), but the CCA will give you a good indication of how robust the battery is and what you can expect.
What happens when a mower battery discharges?
As a mower battery discharges, the plates become covered with sulfate and the acid becomes alkaline. As it charges again, the sulfate in the plates goes back into the acid electrolyte and turns it acidic. As with an automotive battery, the acid content and antimony in the mower's battery can cause corrosion problems.
