These batteries hold their charge really well - It is 18 months since I last bought them and most are only down to half-charge. Other brands are lucky to last a few months.All depends on how often you set the system and how often it gets triggered of course, but I've had other batteries that have just died without any significant use. I also make a point of remotely disabling individual Arlo cameras so they don't waste power detecting movement when the system itself is disarmed. But that strategy is common to all the battery brands I've tried, so these Rapthor ones stand out.If you want a downside, these last so long that they undermine the argument to pay extra for rechargeables, which often fail in Arlo cameras. So pound-for-pound I think these are better value financially, even if rechrgeables are better for the environment.

I buy these in packs of 20, the previous pack, used in 14 of our devices (room sensors and fire alarms) has lasted 28 months. Basically, these batteries remain active for 2 years, and capacity does not reduce during storage for that time. These are seriously good batteries, at a very reasonable price.

Battery life - can't comment Longevity - is that not the same?

Purchased these to replace batteries in wireless Pyronix intruder alarm sensors and they barely last 2/3 months, had more call backs to swap these dying! We use Duracell procell batteries now.

Very happy with these batteries Thank you
