Call me crazy. We have a 2010 Yamaha. For the first replacement I bought a marine battery at Sams the same size and spec as the original automotive one. They are a better battery and are designed for more extreme conditions. Was also $10 cheaper. It held up well and replaced it with the same when the time came.
We are snowbirds which means the cart sits for months in the hot garage. I do
disconnect the negative terminal and keep it on a good trickle charger.

IMO best way to do load test. IMO volts only tells you it need charged or not load test checks ampere or how strong battery is compared to when it was new. I seen lots batteries have 12Vs but no amps. For cranking power.
