بطارية Powerex مشحونة مسبقاً 9.6V 230mAh MHR9VP قابلة لإعادة الشحن 9V

I've used this battery for months in my wireless mic setup and it still holds a charge like new. The fact that it's already charged out of the box saved me from waiting around.

Finally found a 9V rechargeable that actually holds its charge after sitting in the drawer for months. This one still had 85% power after a year, so my multimeter never dies mid-measurement. Perfect for low-drain devices I don't use daily.

I was surprised how well these hold their charge after sitting in a drawer for months — the 85% retention after a year is no joke. They power my wireless microphone for about 40 minutes straight, which is solid for a rechargeable 9V. Only wish the capacity was a bit higher for longer gigs.
