Decent rechargeable battery BUT short lifespan
September 27, 2015
They work well in our wireless mic for a while but they only seem to last for about 8 to 10 months then it's another $16 for another battery.
Provides fairly constant voltage during longer use periods (3 to 5 hours in a wireless microphone).
Battery stops recharging after 8 to 10 months of weekly charging.

One Great Battery!
July 30, 2010
I\'m a lead singer in a band and the 9 volt rechargeables I was using in my wireless mic would last about 3 hours before I needed to change them. I found this battery online, read some of the reviews and thought I\'d give it a try. When I received the battery, I made sure it was fully charged then put it in my wireless mic and turned it on. Ten hours later it was still on!! Wow! Everyone in my band uses the I-Power 520mah batteries now. If you need a battery that will last, it will definitely do the job!

iPower 9v
April 21, 2010
We use these in Lectrosonic wireless mics in a TV studio. The mics are used about 3 hours and then we recharge with the iPower Fast Smart charger, so the batteries see a minimum of 2 cycles per day, EVERY day. We start to see problems after 8 weeks of this type of use. That\'s over 100 charge cycles. Even though these batteries cost significantly more than alkalines, we are saving literally thousands of dollars per year.

LI Reghargeables

I\'ve had these in use now since 11/08 and it\'s 5/09 now. I\'ve recharged them weekly and has saved me a ton of money and trips to the store to buy duracells or energizers. I use them for my wireless band equipment and it\'s not unusual to forget to turn off after each use. Kills the standard batteries but with these, recharge and you\'re good to go. I\'ve had them working for a straight 4 hours for gigs and there\'s still juice left. Not a lot but more than enough to do any gig. They recharge fast too. Like one hour and they\'re done. Not like my 1.5v that take a full 24. You will need to get the charging unit too but, at least I won\'t have had to buy standard 9v for at least a year. They\'re on the expensive side but, you\'ll pay now or pay later with a basket full of throw away\'s.
