Please can some one advise ,if you have a solar panel and two leisure batteries which battery should you connect pannel too the one that's was already fitted with van or the one you had added many thanks theresa
Useful video may help?
Would a 95ah and a 110ah connected in parallel be seen by a charger / solar etc. as a single 205ah battery, or will it charge to the 95ah level?
If they are the same construction, like both wet, I think so.
If you were to make a 205Ah battery all you would do is put the same area of lead as those two in a single container.
You won't do damage wiring them together, fused. Charge them up and see what the result it.
So, charge up the 110Ah, load it up and see how long it runs. Charge the 110Ah and 90Ah separately, wire them together, charge again together ( obviously this will be a short burst ) then apply the same load. If you get nearly double you know it's worked.
Charge again together ( long time now ) and repeat the load test to be sure.
Naturally keep you eye on them while testing, just in case.
The more simple answer is that they will definitely be seen as the sum of the two Ah capacities. The batteries need to of the same construction because the charger will need to be the correct type (unless it can be switched) for either lead acid or gel. A fuse in the +ve link wire between the batteries is often advised in case one battery fails catastrophically and effectively short-circuits its partner (not a common occurrence ). If fitted the fuse should be slightly higher rated than the main supply fuse to the MH electrics.
