### ⭐⭐⭐⭐⭐ Would Buy Again

Would buy again, worked perfectly and easy to install. Good battery life, and good value for the money.

### ⭐⭐⭐⭐⭐ great value and fit
*by M***W on January 12, 2026*

Great value for home alarm batrgtery.

### ⭐⭐⭐⭐⭐ So far so good
*by P***L on January 28, 2023*

I bought 2 7ah batteries for my apc backup that is used for my aquarium. Batteries replaced the lead acid physically with no problems. The backup unit reported partial charge and after a few hours charge reports 600 to 800 minutes of runtime on my filter and lights. I have almost lost my fish due to power loss. I had to use a jug and move water from the sump to the display tank, and let it siphon down, which is a stressful pain I rather not repeat. I have had 3 year life from the original and last 2 sets of lead acid battery replacements. The idea of 10 years for only 2x the money seems like good value. Time will tell on this.
