Does my leisure battery know when it’s had enough?

[Cooper]

I’ve fitted a leisure battery to my T6 (Leoch Xtreme AMG 110ah) which is charged by a Ctek dual 250se and monitored by a BM2 battery monitor. Off the battery I run an inverter, one usb socket and a Chinese diesel heater. I haven’t actually used any of the above for a while but I do like to check the state of the battery with the BM2 quite regularly. Every time I check what the battery is doing it’s getting 13.74(ish) volts pumped into it.
Does it do the battery any harm receiving this voltage every time I drive anywhere? Maybe I would be better off fitting an isolator so it doesn’t get charged on every journey?

I have a CTEK and that manages the charge profile. If it’s wired correctly and includes the correct battery type setting then it’ll take care of itself.

The battery can only absorb so much energy, regardless of what the van is offering the battery if it’s full it’s full

I think it’s all wired up correctly as per the manual and it seems to be working.

Ok great. I didn’t know that but it does make sense. Thanks

13.74v is a typical float-charge voltage, its the most beneficial maintenance voltage for long battery life.
Once the battery is full, any automagic charger be it mains, solar or B2B should revert to around a 13.8v float voltage

If your monitor does current (amps) , you should see this reading drop right down when your battery is fully charged. The voltage reading is the float voltage.
