Hello, I have the P-30 back and the battery is marked 2000mAh 7.2V/Li-ion replace with BP-911/914/915 and I am wondering if this battery that you have listed is the same?? It's marked 2500mAh.
I purchased this to replace the battery on my P24 back. I didn't really pay attention to the mHA ratinds but I can tell you the battery works fine and takes and holds a charge as it should. Hope this helps.
