6 Volt Battery Charger Hooking Up ??

I purchased the charger in the link below to charge my Class A batteries while in storage which is a bank of six 6 volt batteries. The info with the charge says "Maintains up to 8 batteries at one time" but the instruction says to hook up to Pos and Neg post but doesn't say which one of 12 post I have. Should I connect the neg on one end and the pos at other end or just hook to pair or hook it up just to one battery and trickle down the rest?

Off the bank of batteries you will have one Negative that goes to chassis ground and one positive that goes to the coach charging system. Those are the two your looking for.

Be careful what you are saying. "6 Volt Battery Charger Hooking Up ??" is actually misleading. You are hooking up a 12Volt battery charger to a 12Volt battery system composed of six 6Volt batteries arranged to produce required voltage, 12Volts. If you hook charger to battery system as Dennis45 describes, all should work well.

Agree,
A basic knowledge of DC & AC electricity is an asset when messing with these things to prevent pent up smoke from escaping.

Looks like it's my first set of two batteries with the first 6 volt battery in that set POS going across to the inverter/charger and the second battery in the first set NEG going to a frame ground. The other two sets of batteries are just wired together. The charger seems to like it. I checked the Fire Fly system in the coach and reads 13.2 volts on chassis and 12.8 on coach so that shows charging. Correct?

I have a shared 15 amp 110 plug so I'm running both of my charges on 2 amps and that doesn't blow the GFCI plug. What i understand at 2 amps they just maintain and should insure the batteries are at full charge prior to putting in storage. Is this correct....

Thanks for the help...

I assume you will not have shore power while the coach is in storage? If that's the case, I suggest removing the Negative cable from the House battery bank and the Chassis battery bank so there is no parasitic drain.
If you do have power, just leave things as they are and check the water levels on the house batteries (if they are in fact wet cell batteries and not AGMs) every 6-8 weeks.

I sometimes get flamed for saying "There are no six volt batteries in RV's" because.. Well I have two of 'em under the top step

But the fact is they are wired in series so I really have ONE BIG 12 volt battery under that step. And that is what I charge.

So, from this one must assume you are not concerned with releasing Pent Up Smoke.

I am ALWAYS concerned with releasing the magic smoke pent up in our devices.

View each pair of 6 volt batteries as one 12 volt battery.

Connect your battery charger to the positive and negative battery posts that have the large wires connecting to the coach.

I have 4-6 volt coach batteries in my '03 Fleetwood Revolution, and have hooked up my charger as described above. Charger set at 12 volts, 10 amp setting. After charging overnight, the battery level indicator inside the coach has not changed, still showing charge level at its lowest level.

Any suggestions? Is the charger level not high enough? Thanks!

Mark

Have you checked the battery voltage with your voltmeter?

If it's 13+ volts, the batteries are fully charged and the charger is doing what it's designed to do by not overcharging the batteries.

I would suggest to start a new thread rather than tagging inside another, for best exposure and not to divert. Imho.
