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:
9volt date voltage charged
#1 7/10/2013 8.26 3months ago
#2 7/10/2013 8.27 3months ago
#1 7/10/2013 8.31 10min charge to full
#2 7/10/2013 8.31 10min charge to full
#1 7/10/2013 8 after using included LED light for 1 hour
#1 7/12/2013 5.26 after 53 hours of LED
#2 7/12/2013 8.34 after 53 hours of charge
#1 8/21/2013 8.35 after 40days on charger
#2 8/21/2013 8.29 after 40days standby
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.
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.Read more ›

One out of the four batteries was DOA and would not take a charge. I can make and educated guess and say the quality control at Maximal Power leaves something to be desired. Read morePublished 1 month ago by JohnSD
