Good so far

Delivered 3 days earlier than stated. Have had the battery installed for just under 2 weeks. So far so good but can't speak to the longevity of the product yet.

battery was correct replacement for Chamberlain garage door opener. the box offers a 3 month warranty extension on the 1 year warranty. the original battery had 01/14/16 manufacturing install date and it's 8/8/25. noticed the time and date were resetting after short power interruptions for some time.
