I have a Sony digital camera and since I bougt it I use the Sony batteries Ni-MH ( NH-AA-DA HR15/51 1.2v 2100mAh ) and now I would like to use not a sony batteries a NiMH AA 2500mAhet 1.25V could I use this batterie with out problem.

Thank you for the answer

The AA-size 1.25V NiMH should work just fine.

Since your old batteries were also NiMH, you should probably be able to use the new set with the battery charger you already have. It may take slightly longer to charge since the new ones have a higher capacity to fill (2500mAh vs. 2100mAh)

If you are planning to dispose of the Sony batteries, you can look up a place to recycle them at.

I hope this was helpful.
