Very interesting Report on Leisure Batteries (1 Viewer)

[Forestboy]

Dyno traction mono blocs, charged by a Sterling Alternator to Battery charger.

7 years old with full capacity.

Same batteries as us no more so called Leisure Batts for us the last ones Banner failed in the Alps.
Dyno tractions have been brilliant and we do give em a bashing.

I use the voltage display on the inverter. It tallies with my multimeter.
20% charge is a no-load voltage of approx 11.6 volts.

So do you see an on-load voltage of lower than 11.6v ?

So do you see an on-load voltage of lower than 11.6v ?

Yes, most often when the compressor, kettle or hairdryer is on! Under a healthy 100 amp load, voltage can drop to just under 11v. All appliances are around 1100w. The compressor is used to inflate our canoe!
Usually with the normal MH type loads, ie. blown air, lights, TV, water pump, the voltage will drop to no lower than about 11.2v at around 80% depth of discharge (11.6v no load volts).

Bear in mind, we have a healthy 345Ah traction battery bank. A 100 amp load on a single leisure battery will drag it down very quickly.
