Liftmaster Battery Backup

Easy to find and order this backup battery online, thanks to the pictures and description. The instructions, along with a YouTube video, made it easy for me--a 71-year-old woman--to install this battery myself in a couple minutes. Battery arrived timely and in good conditions.

Great deal!

The battery was recently manufactured and had the sticker on outside of box--could see right away. Also had a sticker with that info plus a space where you could write the date it was installed. Fast arrival!! Fair price...lower than other retailers! Last, exact same battery, lasted longer than what I found when researching.
