Charging 6 V batteries

[Ultra912]

How do I charge two in-line 6 V batteries with a 12volt charger
Had my maintainer on 12 V battery and I guess I need to separately charge the six volts since they went all winter without being maintained

Hook them up in series, one cable positive on one batt to negative of the other batt, then hook your charger up to the unused terminals.

I’m asking about attaching the battery maintainer. The batteries are already installed in series just like the diagram. Where do I put the battery maintainer clamps. Red on the positive of one battery and Black on the negative on the other battery

I only ask because it’s a 12 V maintainer and the batteries are 6 V. If the positive is connected on one battery in the negative is connected on the other battery does that mean it’s charging 12 V because there are two 6 V batteries?

You would attach the leads ( using post #3 pic). Positive to 12 out terminal, negative to ground terminal .

Yes, exactly how MK1MOD0 said in the above post. Being it’s charging/maintaining 2 - 6 volts will take longer initially. I have 4 - 6 volts on my Moho and a 12 volt for starting. Same principle with the 4 - 6 volts.

You need to buy a charger with a minimum 10 amp charge capability to perform the initial charge on your batteries. A .5 amp maintainer won't cut it. You'll end up with sulfated plates, and a permanent reduction in battery capacity each time they're discharged and reconnected to the maintainer. That means a shortened lifespan and $$$ out of your pocket.

You don't have to take my word for it. Go to the battery university website and read up on the subject.

Thanks you guys. I actually put the maintainer on it last night and it is a 1.5 amp and the batteries were fully charged this morning. I think the long ride from Havasu to Topock and back charged them up
