Hello!

Does anyone know the difference between ECS and CCS charging methods? Which one is better? Are there any pre-made chargers available (I was only able to find descriptions how to build your own CCS charger)?

While at it, are -dU chargers really that bad? I have an Ansmann device that can charge up to 4 AA or AAA batteries and I never had problems with it - however, the batteries tend to get really hot short before the charger switches to trickle charge. Now since I also need a charger for C and D batteries, I was wondering if I should get another Ansmann (Energy 8 or whatever they are called) that also operates using -dU.

Regards,
Sebastian

A friend mentioned this charger company to me and I have had great success with it.

I use NiMH.

Thanks for that. It seems that the charger you mentioned is also based on the "older" -dU method, although it has a pretty sensitive controller (if their statement is valid). What makes me suspicious is their mentioned deep-discharge function - deep-discharging is something that should actually be avoided.
Anyways, the charger doesn't seem to support C and D batteries.
Edit: Ah, also found chargers for C and D batteries.

Also, I am really interested to know the difference between the ECS and CCS methods. CiTay once recommended CCS chargers over -dU and I have to agree with him since -dU chargers cut the power or switch to trickle charge after the battery is already a bit (or a bit more if the controller is not sensitive enough) overcharged. Also, I didn't find any company to make chargers based on CCS or ECS method - I was only able to find pieces for making your own charger.
