    Purchased this to replace the battery backup in a chamberlain garage door opener. Fits fine and easy install. Has been working fine over the last few months. Nothing spectacular that would warrant a 5-star rating, but satisfied with the product.

    Just what I needed to replace battery in my LiftMaster after five years sending me message that it needed replacement. Arrived right on time and great price. Half what local dealer charges plus easy to change out. Just remove one screw, slip out the old battery and slide in the new and reconnect the two color coded leads.

    too early to review although there are no problems yet. Original battery conked out within a year and half.

    The battery was reasonably priced and arrived promptly. This is my second purchase of this product and when the time comes for replacement I will most likely buy it here.

Came as expected and was fully charged 12.94v

Battery arrived in excellent condition. Even though it is the same 9ah size battery as the original one I am replacing, it is a slightly smaller size package requiring me to add extra washers as spacers on the battery hold down bolts. No big deal just be aware you may need to do the same thing. I hope this one lasts as long as the previous brand did.
