Speaking of batteries

[cybrfire]

After watching the "famous Optima" video of Dave's, got me to thinking.

You supposed to keep a battery on a maintenance charger of some sort or at least put it on the charger from time to time when in storage. That's all fine and Dandy. I currently have 4 batteries pulled from vehicles for the winter months that will need some sort of maintenance charger. Probably more to come yet.

Can they simply be wired together the way you would in a vehicle and all maintained with one charger? Is there such a thing as too many batteries on one charger?

If you use a battery "maintainer"- the amperage should be low enough where it shouldn't be an issue. Optimas will only really maintain a charge on a trickle charger if you wire it parallel to another battery because of the low resistance in the plates or some b.s that I was told by Optima a few years back.

I shouldn't have posted at all in Zim's thread, my Yellow Optima seems jinxed now... with the experience this summer, I just ordered a solar battery maintainer; we'll see how that does.

if you wire them in parrell it would be the same thing as having one huge 12 volt battery. My high school auto teacher used to do this with batteries to keep them charged, he would wire a bunch together to a trickle charger to maintain them for long periods of time

The modern chargers (like CTEK) don't require this trick.

Just set them to "snowflake" mode which is the correct setting for maintaining AGM batteries like the Optima.
