Any make/model recommendations, based on direct experience, for an
RF-quiet battery charger+maintainer, AGM or flooded deep cycle
lead-acid, 12 VDC, 3 to 5 A rating?
For at least ten years, I've used a re-purposed PSU for a defunct
Thinkpad,with a Genasun MPPT Charge Regulator (for solar systems) to
maintain a 100Ah SLA battery in my shack. It runs non-radio 12V gear in
my shack. A second Thinkpad PSU and Genasun maintain the 100Ah LiFePO4
battery that runs Elecraft K4 and K3 rigs for my SO2R contesting setup.
The LiFePO4 battery is used because it stays above 12.8V under load; the
SLA lives around 11.4V under load, where the radios produce much higher
IMD on transmit (clicks, splatter).
