Style Name: Combo 9V Verified Purchase
01/28/2013 - Used in cordless/hands-free Mics in church. Very good capacity - lasts 4+ hours and charges. works well so far and i plan on buying more if we get more of the same mics.

05/04/2013 - Update:
After twice weekly use, the batteries DO NOT last more than 20-30 mins now (always returned to charger after each use). I know that Lithium-ion batteries should last 1000+ recharges with 80% depth of discharge, and GOOD Ni-Cd batteries recharge 100s of times, so there is something suspect with these. ..

08/21/2013 - Update:
These batteries have a larger mAh capacity because they are "lower" voltage. If you don't need 9volts, like the included LED flashlight which ran for 53 hours(!) with usable light, these will work very well. If you need them for a "higher" voltage application these will have limited use. For me, these were used in a wireless microphone system that was near the base for the first month then I started using them farther from the base and they did not perform well. Below are the results of my tests:

Bought these for a TENS/IF/MIC/EMS system, it eats 9v batteries. This is based on first cycle on the charges so take it for that. I am getting roughly twice the duration as I was using Duracell 9v batteries and substantial increase in amperage. Charge time is roughly 8 hours. The charger has fold in prongs so its easy to pack and travel with. If the batteries last through as many charge cycles as they should being li-ion, I will be very happy.

It lasts long as alcaline in my effects pedals for guitar. I've re-charged it 10 times so far and ir really works as advertised. Love it.
Also, do the homework, can be found much cheaper on Ebay incl. shipment, so I don't know why it is priced so high at Amazon. Anyway high recommendation for this product.

I ordered this charger with Maximal Power 9-Volt Li-ion 550mAh Rechargeable Battery. At first it seemed as if the battery (or tester) was defective, but on further troubleshooting I found out that the battery works fine and the powered product is defective. The instructions say to charge for 10 hours on the first charge, but the 'charged' light comes on after 2 hours which seems a bit confusing, since you'd naturally think that it stopped charging.

Review updated on 2015-06-10.

This battery has been the perfect upgrade for a Powerex 300 mAh 9V rechargeable battery. That battery would last 3 weeks in a wireless microphone when new. After some time, it would last closer to 2 weeks. After two years of use, I was searching for a replacement that would work for at least one month between charges. In order to accomplish that, I knew that I had to find a >=500 mAh battery. After some online search, I found that the Li-Ion 9V batteries would meet that requirement and I settle on this one because it had good reviews and a good price.

I have been using this battery for 3 years and 4 months. It takes between 45 and 50 days of normal use to get discharged, when the previous had to be recharged in 21 days at its prime. Also, it is noticeable lighter than the NiMH battery it replaced. Another advantage is that Li-Ion batteries have a longer life than NiMH. In my experience, with different types and brands of NiMH batteries, they provide 80 full charge cycles at best and about 50-60 on average, despite the claim that they can reach up to 300 cycles. HA, HA. This Li-Ion battery is of the same technology as a cellular telephone battery, and will have peak performance through several hundred charge cycles, just like a cell phone battery.

This battery has automatic shut down protection, which means that it can not be discharged to the point where the cells are damaged from depletion. The battery will stop delivering current before this happens.

The full charged voltage for this battery seems to be 8.4V for two 4.2V cells (4.2V x 2 = 8.4V). If that is the case, no matter how long you leave it in a charger, it will not charge to higher than 8.4V.

I am a gigging musician and my wireless in ear monitor receiver uses a 9V battery. I got tired of spending so much money on alkaline batteries, so I invested in these rechargeable batteries. They have worked great. they last more than the length of our full show and have paid for themselves many times over. My singer also purchased them for his wireless microphone. I highly recommend them for anyone who wanted a good quality battery and it tired of spending money on ones that you end up throwing away when you are finished with them.
