battery backup units

Message #1 - Posted 2007/10/28 - magdalena

I just bought my first-ever battery backup unit (an APC brand 750A model). The inspection sheet taped to it is dated 11-17-05. Is this normal? Is the battery as good as new when it's been sitting on a shelf for two years? (One terminal needed to be connected by me, the consumer, per the instructions.)

If you want to be sure, contact APC. My (non-APC) UPS batteries lasted something over 5 years.

While its true that "you can't fix stupid", apparently you can package it up and sell it. -- fnorgby on TMBO

You'd have to measure it with a meter to be sure. If it's fallen to less than 5-6v it may be gone forever. But you may get lucky. Just plug it in for a day or so, and see if it will sustain a load on it.

Thats the normal way to ship the backs ups. On the other hand I don't know the shelf life of the unused battery. You might try looking up the Manufacturer and see if they have info on their web page.

Depends on the type of battery. Many gel-cells are surprisingly stable holding a small charge for years.
