Show 1.0 out of 5 stars This product is a not a genuine Chamberlain battery but a generic knock-off brand. This product is completely deceiving as it shows a photo of Chamberlain battery and no where in the description does it mention a generic brand was to be sold instead of the OEM. Had I known this is a generic brand I would never have purchased this product and feel that the product description along with the photo used is very misleading to consumers. I don't want to risk the chance of these cheap batteries catching fire or not lasting as long as the OEM brand. I've already filed a dispute with Amazon to get a refund.

Reviewed in the United States on October 13, 2022 The battery arrived on time and was very easy to install. Simply turn iff power to unit, pull out the old battery, disconnect two wires, connect the new battery, and shove it in. Then restore power. Doesn't get any easier than that.
