This is not specifically camera related but thought you guys get through a fair few batteries and I did not want to ask in the Zoo which is GD 
When I was a lad (I am 33 now) rechargeable batteries if I recall correctly were rather pap.
Nowadays, if I understand correctly, Alkaline is now showing its age.
I need AA, AAA, C, D batteries.
The main reason is the silly money I am spending on alkaline batteries for kids toys which do not seem to last that long. 3 kids between the ages of 6 and 1, we have batteries everywhere.
If I can get an all in one charger, then great, if I am best to get a seoerate ones, so be it.
I would like the chargers to be able to charge different batteries at the same time, so for example, the ability to charge AA and D together. Auto cut off once charged would be nice to.
Also, do any of the chargers have the ability to tell you how charged the battery is?
Many thanks.
James.
