Temperature and Battery life (1 Viewer)

[SandraL]

Battery life is shortened if battery is at a higher temp. So this nice weather is shortening the life of our batteries.

The optimum operating temperature for the lead-acid battery is 25°C (77°F). As a guideline, every 8°C (15°F) rise in temperature will cut the battery life in half.
Temperature effects on sealed lead acid batteries and charging ...

We have a votronic solar controller with temp sensor mounted on the leisure battery.

In this warm weather it has reduced the float voltage from 13.8 v to 13.5v
which will help to keep temp down.

We rarely use mains power, .but if we did our mains charger has no compensation for high temp, so battery life will be shorter than if we just use the solar with compensation. For me answer is to disc onnect mains from charger and rely on solar in these temps.

Any thoughts?

Nope!

Yep, don't worry about it. You don't have much choice in a Motorhome to where the batteries are fitted and not easy to move them, anyway how long in life do they spend over 25° not that much. My batteries are next to the heater am I worried, no, can't do anything about it so why worry. You don't hear of batteries falling over all the time in hot countries like Spain & Italy.

Fit a computer fan like you do on the fridge

Fit fan and blow hot air over them.

And run the fan off the batteries?

I think for the short time we get hot weather in this country you aren't likely to notice the difference?

Winter is more of a problem with my batteries next to the heater.

not bothered either..

thinking on it.. vehicle starter batteries are generally under the bonnet near the engine.. how do they cope ?

So in desert countries (Arab states etc) where the temperatures are regularly in the mid 30s, and far hotter under the bonnet, they buy new car/van/truck/bus batteries every 18 months.
