Pulling my weight
Thanks for the update, @CaliGirl. I've been wondering how you fared
I'm going to assume that, by "backup power supplies" you mean UPS'? Three things:The back up power supplies that I bought we’re helpful, but after one year one of them has already died and I can’t get it to charge or work properly.
- If these UPS' are being charged/discharged frequently, their lives will be shortened, particularly if they're being discharged deeply
- In your OP your noted "outdoor cameras need to handle -10F." If the UPS' are reaching temperatures like that it will significantly impact both battery performance and life
- Some UPS' still allow user-replaceable batteries. It's not hard and battery replacement is a lot less expensive than whole UPS replacement. A lot friendlier for the environment, too.
