I’ve just added a second battery to my domestic bank to give 2 x 110Ah.
I’ve only just realised that my current charger is a CTEK MXS5.0 which is rated for a maximum of 110Ah batteries.
It outputs 5A.
According to the Calder Bible a lower rated charger will just take a much longer time to charge a larger battery bank (and be beneficial to the battery!).
Is that OK or should I really upgrade the charger? It’s always plugged into shore power, except when in use! So time is not an issue!
It has gone through a full charge cycle and is now at the maintenance stage. However, the batteries were charged when fitted. It spent about 18 hours on the bulk charge stage. At no time was it too hot!
Am I being naive?
Cheers
