Is it necessary to discharge modern NiMH baterries??

Question

Hello, I've read that though NiMH batteries are better than NiCad in terms of memory effect, it is still slightly susceptible to it. Others say that NiMH does not have the memory effect at all. With modern NiMH chemistries, is an occasional full discharge still necessary?

I have some pretty new rechargeable energizers and I want to know the best way to store and maintain them.

Answer 1

Yes if it is a chargeable battery you can keep under sun light no need to waste electricity  

Answer 2

Don't recharge the batteries everytime(like u would not recharge ur phone everyday to prevent the baterry from over charging an melting.),

  Check the back of the battery also,their would be some informations.

Answer 3

Technically, NiMH batteries do not have a "memory effect", but strictly speaking neither do NiCds.  However NiMH batteries can experience voltage depletion, also called voltage depression, similar to that of NiCd batteries, but the effect is normally  less noticeable.  To completely eliminate the possibility of NiMH batteries suffering any voltage depletion effect  manufacturers recommend an OCCASIONAL, complete discharge of NiMH batteries followed by a full recharge. NiMH batteries can also be damaged by overcharge and improper storage (see the NiCd section immediately above this one). Most users of NiMH batteries don't have to be concerned with this voltage depletion effect.  But if you use a device say a flashlight, radio, or digital camera for only a short time every day and then charge the batteries every night, you will need to let the NiMH (or NiCd) batteries run down occasionally.
