ni-cad vs ni-mh batts.

I just got a new cordless phone & is has a ni-MH batt. Do ni-MH batts. have to be fully discharged before recharging? Will they build a memory like ni cads if not fully discharged? Thanks, Mike

Nickel metal hydride (NiMH) batteries do not develop a memory like NiCad batteries, and do not need to be fully disacharged before recharging them.

Take a look at this article ( - he poses some very interesting theories about "battery memory".

To summarize - there no such thing as memory effect in cell phone batteries. Either NiCad or NiMh or LiI.

What makes a NiCad cell phone battery any different than any other Nicad battery.

I've used both in my digital products. The Nicads died long ago. The Nickel Metal Hydrides are still putting out juice.

I'm not sure of the 'article'.
