Battery Hydrometer – Acid Tester, Electrolyte Density Checker

Installed easy! Delivered quickly too and my car has started every time since!

Good battery at a good price. Home Depot did well tracking my order. USPS did what they always do. Delay, delay, delay. Nine days to get to NJ to Jax Florida. I guess their Yak had a bum leg.

This little battery has some power behind it. Immediately starts my Tao Tao atv 125

So far so good!!!

I have been ordering Mighty Max batteries for a while now. They always perform well and usually last a minimum of 3-5 years

Came quickly, can leave it plugged in and doesn't hurt life

I had an old Stanley (Jump/Compressor) combo unit that stopped working/ charging. I was going to throw it away, but decided to open it and look inside. I found it had a 17 Ah (12 v battery). I tested the unit with my car battery and it worked so did a quick search on Amazon and quite a few battery options came up. I chose Mighty battery based on price and reviews. I ordered on Amazon it arrived overnight. I just replaced the battery, put the thing back together and it works fine. The package arrived in perfect condition, charged to 12.7v (I measure using my multimeter). So far everything looks perfect.

Ordered this Mighty Max battery as a replacement for the one that came with my garden tractor. OEM version was 3X the price of the Mighty Max which is a drop in replacement. The packaging was good, the battery itself looks well made and the specifications are identical to the OEM replacement battery. So far, so good.
