Purchased as replacement of the original battery for PRO/fit percussion muscle massager model 8033. Fit and works as it should. BUT, as mentioned in other reviews, the polarity does not match as it should be. ????? And it requires some cutting and soldering job to make it right ✅️.

I have an aqua ez pool vacuum and the battery was starting to not hold a charge, when you think it doesn't get sued every day or week after a few years isn't bad. This battery replaced the original perfectly, popped in and charged up right away, been running great ever since.

Doesn't seem to hold charge

Prompt shipping , product as described!

Burned a hole in itself after 2nd charge.I purchased this to replace the battery in a Jacuzzi pool vac. Same specs as OEM.It had some charge when it was received. Installed the battery, charged the unit and used it. 2nd charge did not last as long. Would not charge a 3rd time. I disassembled the unit and found that the onboard chip fried. Or at least I am assuming that is what fried since I did not burn my house down.This is supposedly a reputable brand but I’ll think twice about charging any aftermarket lithium batteries in or near the house.
