Leaving the batteries in the charger...?

[herbeapuce]

HI.

I have a Maha-C204W

I have some Energiser 2500, some Sony 2500, some Eneloop 2000 AA batteries...

I also have some AAA...


Now is it good or not to leave the batteries in the charger at all time?

It feels some batteries get warm at some point

what is the best way to use my charger please?
