Title: Will wait to see if battery lasts 30 years like its predecessor, but ease of purchase & reasonable price get high marks
Review: Replacing the backup battery for a home security system is not something we think about doing until the system lets us know the battery is about dead. Mine did, and I looked locally for a replacement but then found this online supplier, made a few clicks with my mouse, and it was on its way. My only knock will be if it is less durable than the original battery.
Is the review positive or negative?
