3 amps divided by 2 Batteries = 1.5 per battery, I'd think that would do better than the 1 amp per battery, as most trickle chargers sold seem to be 1.5V per battery.
Minor point, the alternator (A2's) draws current as it sits idle in the motorpool, which over 30 days drew down the batteries. Hence the development and fielding of the 24V "solargizer" mounted to cowlings to trickle charge the batteries.

I tried the solargizer, but didn't have success (mainly as I seldom drove my M825 TOW jeep anywhere.. :( .)
If I were to recommend anything, a kill switch hooked onto the negative cable of the grounded battery to isolate the whole system would provide you with zero drain, and some extra security as far as theft goes. Mounted in the passenger foot well by the inner frame member it is not very noticable, and if wired so when bumped it remains 'on', a passengers boot wouldn't kill it during driving.
Just a thought after owning several for many years.

I use the NOKO Genius G7200 Smart Charger, it has 12 Volt and 24 Volt capability and is 7.2Amp. It has doubled the life of the 2HN Batteries in my M-38A1
