Nice fit for genie 7155l garage door opener
Was a bit skeptical if this will fit my garage door opener. It fit perfect on my genie 7155l. The installation took maybe 10 mins. Tested it by removing power plug for the opener and I could open the door without power. The battery did need overnight charging before I could test it.

Brand-new power battery...
My brother-in-law installed the new 12v battery the garage-door opener for my aunt, since I wasn't there. Appears to be working OK, so far ( its 'only been 2-days since received delivery). So, no more "beeping" which normally means low battery power for power back-up use and need to be replaced. It lasted about 5 years, so that's normal for such. Also I always put the date installed on it to see how long it eventually lasts.

So far so fine as name manufacturer replacement battery
So far so good on these batteries. I bought two of them to replace my Liftmaster brand batteries that came with my Liftmaster garage door openers. I noticed the replacement batteries are much lighter. I hope they last as long as the Liftmaster brand of battery, 4.5 years. These batteries were easy to install and worked exactly as expected. I just hope they have a long life, like the name brand. I will update if I have any problems. But so far so good.
