Help Selecting Battery Charger Size...84FC

[dthollis1961]

My Todd Engineering semi-smart 75 amp charger-converter has bit the
dust. As long as it was working, I didn't give chargers a second
thought. It kept the batteries up and when they needed water, I
watered them.

Now, having to get a new one, I have been looking for the correct amp
rating for the charger and am more confused the longer I look. My FC
has 4-6v batteries with a combined rating of about 450 amp hours. I
have seen recommendations of between 10% to 25% of battery AH for the
charger rating. That would be somewhere between 45-112 amps. Well
that's not much help! I think when this thing was new it came with two
75 amp chargers...that's off the chart.

I do dry camp occasionally and like to run the generator about one hour
in the morning and again in the evening. The 75 amp I had seemed to do
OK with that.

What size charger works for you? I don't always so the right thing,
but I at least like to know what the right thing is.

Thanks,

50 or 55 amp works, just be sure they are smart chargers. I got mine from Progressive, check the Hot Deals. If you need more info. email me and I'll get out the details and let you know.
