The older EN-EL15 batteries are losing it and I noticed that the replacement battery is the EN-EL15a. Are there any issues with using the MH-25 rather than the newer MH-25A to charge the EN-EL15a? The three current MH-25 chargers are just fine so it would be nice to avoid buying any MH-25A if possible. Thanks.
I have both types of chargers and batteries, and don't seem to have any issues interchanging them. I believe the MH-25A and MH-25 are functionally identical
