Connector

[This review was collected as part of a promotion.] This replacement battery for my garage door opener came quickly after ordering.  I followed the detailed instructions as to how to remove the old battery and install this new one.  It was easy to do and worked great after installation.  I saved over $100 by doing this myself.

Easy Replacement

walmart.com

[This review was collected as part of a promotion.] Our garage door lifting mechanism battery started beeping incessantly. It was so irritating and it required replacement. The garage door company was way too expensive, so we did it on our own with this wonderful battery replacement. It worked as expected, and the installation instructions were clear.

Reliable battery

[This review was collected as part of a promotion.] Extremely happy with this battery so far. It did take a little longer than the suggested 24 hours to charge but I had a back up.

Good buy

The only issue I had was the OEM wire connector was smaller than the new battery pole on one side. I simply ground a little of the new battery pole down enough for the OEM wire to fit. (Chamberlain probably does that so most folks would order the more expensive OEM battery). This battery was the perfect replacement at HALF the cost of OEM. It worked perfectly after installation. Highly recommend,

Same size, Same Performance, Half the Price

It's a good replacement battery however there was no mention that your connectors could be a different size.  My negative side was smaller and i had to go out and purchase an adaptor terminal.  Not a big deal but it would be nice to know in advance.

The only complain I have is I need to filed down the negative (black) terminal to fit the existing connector. Still a good buy.

batteryclerk.ca

All the specs were perfect for this replacement battery except for one.  The two tabs on this unit are significantly larger than the tabs on the original battery, so it required me to crimp on new wire ends in order to make a good connection.

The leads are bigger than original battery

Battery was in good condition but the connectors did not fit with my wires so had to order an adaptor. But customer service was prompt in responding to my inquiry

Good quality, but double check the compatibility
