Feature: Actual Voltage is slightly higher than standard 9V Alkaline Batteries. Will outperform a standard 9 volt rechargeable battery due to the higher voltage. PowerEx 9.6V 9V batteries will operate paintball hoppers and wireless devices that other 9V rechargeable batteries cannot power. Enables wireless microphones and paintball hoppers to last longer and work faster.
Powerex are extremely high quality. (my opinion). They are not cheapy junk and cost a little more than others. "Most" of their batteries are actually manufactured in Japan, not China. I use the C cell versions in my older White's unit. They last forever. Hold their charge like you wouldn't believe. Way better than american branded (made in china or some other funky place) rechargeables. These should have the juice to power your unit. They carry a 1 year warranty. My 2 cents worth
Now don't make the mistake of thinking of going to a higher mAh version is better:
example: "Maha MHR84VI 1-pack 250mAh 9V Ni-MH Rechargeable Batteries"
These will only actually push 8.4v, thats why you need True 9.6 volt version I first listed
