A/S In Heated Storage, Negative Disconnected

Looking for some guidance on periodic charging of dual batteries while my 19C is in heated winter storage. Have disconnected the negative but positives are still connected. Can I top up the charge on both batteries at the same time?

Jack

A stand-alone automatic charger is what I would use.

So long as the charger’s leads connect with their respective terminals on both batteries, all is fine.

A good automatic charger could be left on full time..

Regards,

JD

Totally agree.

Look at the BatteryMinder 128 - it is designed to be connected to the battery bank 24/7, compensates for ambient temperature, delivers up to 2/4 or 8 amps depending on how many batteries you have in parallel, and periodically delivers desulfurization.

Will keep your batteries healthy.

Welcome Aboard!! 👍

Yes...Connect and use your converter when the voltage drops to 12.4v

Yes...with a standalone charger,(not a maintainer), connected in the AS, + on one batteries + post, - on the second batteries - post.

If using a maintainer...Make sure the batteries are fully charged and leave it on 24/7

I've used both methods but preferred the first, made little sense not to use the AS's converter, as our AS is on the home pad with 30a ac.
Even with the AS supplied converters, if only charged when needed and checked regularly you won't have a problem.

best to disconnect the -ve lead

BTW, we took out the Lion battery this winter and installed the old lead acid battery so that we can work on and monitor the As over winter

it has been cool the last few weeks
