Anyone got a link to an alarm system battery checker? Using a regular DMM doesn't necessarily cut it, for me, so I've been putting a load on alarm batteries with an incandescent lamp during the annual PM to check them. ELK makes an alarm battery checker that relies on baseline measurements from when the battery was installed new, which is somewhat unrealistic considering that I might not have been the one to put in the new battery. I've got a decent one for UPS batteries, but it doesn't go low enough to check the 4 - 7.5 amp-hour batteries normally found in security/fire/access control panels.
