Powerex MHR84V Powerex 9V 300mAh 1-Pack Rechargeable Battery

I purchased this for use in a portable headphone amplifier I built (AMB Labs Mini3) and since constructing it, I have not needed to open the amp, it charges well, lasts a decent amount of time and has been going strong for a year now! If you need a rechargable 9 volt, this will meet your needs and provide reliable performance for quite some time.Recommended.

We have used these extensively in a metal detecting pin pointer. They run out much more quickly than other regulars 9V. However, this is a money saver really over time.Just bring along an extra. They also didn't seem to hold a charge very well in the beginning. But now they hold a charge much longer than before. So it's probably a breaking in process.

I used to use these for paintball and now I use them for my touch faucet. They last far longer than non rechargeable and as long as you have a decent charger they charge fast. Great product.

Use this in a share Beta58 wireless for a karaoke show. Shows run 4 to 5 hours and it always lasts the whole show. Provides plenty of power for the Mic to work perfectly.

but this one is a winner, a lot of rechargeable 9v batteries range from 7.2v, 8.4, and 9.6, depending on how sensitive your gear is select carefully. This one works great in my kids remote controls, they constantly forget to switch them off, so that would have been very expensive in alkaline versions.powerex and Maha are superb brands when it comes to rechargeable batteries and chargers

charge up to 1000 time? you gotta be kidding me.i charge this batteries (i bought 2) for about 50 times (60 at the most) and they exploded on the bottom, therefore they could no longer charge.i did charge it with the recommended charger, so that is out of the question.

Great 9 volt batteries! Recharges fast and lasts long!
