Review: Great replacement - Replaced the lead acid battery in my 15kw portable generator. Man, that is so yesterday and the sucker leaked acid all over the metal battery box. This works like a charm, supposed to last 10 years, and weighs less than half as much. If you buy a lipo battery be sure to get the right charger to keep it topped up!
Review: Garage door opener backup battery replaced - Used to replace back up battery for Chamberlain garage door opener in Chicago. Bought and installed late April 2023. Still working strong (now Jan 2025). Will update when needs be replaced. Reluctant at first since different technology and material. Easy to install.

### ⭐ Barely lasted 4 months!!!!
*by T***S on November 17, 2023*

Super light batteries, less than half the weight of the originals! I guess you get what you pay for. Bought these in July 2023 - dead (not taking charge by mid-Oct 2023. Of course too late to return.. I hope the seller would reach out.
