do I need a new leisure battery

[Bynxy]

Asking the question because when I am running on battery only the fridge just about gets cold because even on the most sunny days I am getting excellent voltage on the solar but when the dometic fridge kicks in the voltage on the battery drops then when the fridge stops because the voltage has dropped below 11v the voltage comes back up on the battery and the whole cycle starts again !!!!!

check the

Firmware update due. . .

do that first.

for the LB to drop below 12.0v when the fridge kicks in, indicates.

either a very flat Leisure battery,

or a knackered L battery that wont take a charge and hold it.

or a faulty fridge drawing excessive current (very unlikely)

Software is up to date and still does the same even on a really bright day its starting to drive me bananas

How old is your current leisure battery?

What type is it?

Have you ever let it drop below 50% charge (as I'm assuming from the voltages it's likely a lead acid)

Does your app show you the charging history, if so can you grab some screenshots?
