Hi I have a 200 ah lithium battery in our bus that looses it capacity quite quickly
I have had it on charge by mains power and it still doesnt come up as showing full charged on my victron charger even after 10 hours of charge two days in a row with only the fridge on
the battery is of a good quality brand about 4 years old
when the bus is parked at home the battery is charged/ maintained by solar which is 600 watts
can anybody have a idea if this could indicate the battery is on the way out please

Shouldn't be a problem with Victron batteries.

HI We do need more information to give a sensible answer.
Has there been any changes to the system lately.
How do you judge the battery capacity. Any meters or ? to indicate capacity.
What is the fridge current draw ?
Has the charger settings been set correctly to suit that battery.
Does the battery have a BMS internally.

Hi and welcome!
Does the battery charge ok on solar and is it only on 240V/12V charging that you have the problem?
A four year lithium battery should still be like new.
How are you testing the State Of Charge of the battery?
What is the solar controller indicating the voltage of the battery?
