GM,
Powersonic sells automatic chargers for SLA batteries that do just what you
described, Don, The PSC 12500A is the right charger for the KBT-2. That's
the 0.5 amp charger. I keep my KBT-2 on float/charge with the PSC 12500A
with the battery switch off unless I am on battery power, and
Now I have a question for the list regarding charging the K2 battery.
I have the battery out of my K2 (while the KPA100 is installed), and
I want to make sure the battery is charged. I have a Sears 1.5 Amp

Thanks for adding that - in my haste, I forgot to say that indeed for a
Smartcharger, the current must be set with consideration for the battery.
OTOH, I believe the thing that is usually adjusted is the 'bulk current'
which is the high current part of the 3 stage charging cycle.
