Thanks for the comments and ideas for a K2 battery charger. This would simply
be to charge the battery when away from home, so I don’t really care about RF
noise.

Although you can certainly use it just for charging an SLA, one advantage of
these types of chargers is they automatically go into float mode to maintain
the charge and prolong the life of the battery. This is particularly
beneficial for batteries that go fairly long periods of disuse, like
Hi Jim,
Excellent article. I haven't checked if it is a source of noise, but it
doesn't quite matter because this is a charger, not a power supply. I only
use it when I need to charge a battery, so it is OK.

Hi Doug,
I use this, and it seems to be working very well. When you order, make
sure you specify a 14.8V (or 14.6V) model.
Some reviews complain that the voltage measurement is only 12V, but mine
clearly shows 14.8V on my Fluke meter.
I use a small wall wart type lead acid battery charger/maintainer as the type
used for moto and lawn equipment. I use a Battery Tender brand charger I got
many years ago. You might check out their line, which starts at $45. Similar
cheaper chargers can be found on line. I've never

Ah -- you don't have enough RF noise, and you're looking for more!

Looking for ideas for a cheap 14 volt wall wart type power supply for
recharging the KBT2 battery. Is there one available that has the right plug? I
see lots of 12 volt and 14.4 volt chargers out there, but???
Thanks, Doug, W0UHU.
