EV> TW> Somewhare i nmy rats nest I have a computerized battery tester I used
EV> TW> to use for my Ham Station exergency batteries. Id did a test discharge
EV> TW> curve plot and when the batteries were less then 50% of their AH rating
EV> TW> I reppaced them.

EV>All I've ever done is once in a while to press the Test Button on the UPS

I had in my Active Ham days 8 Rechargable handheld packs and several 7
