Tenergy Centura 9V 200mAh Batteries:
Standard size 9V rectangular battery: Dimensions: (H x L x W): 48mm x 26mm x 16mm
Low Self Discharge (LSD) Technology - when the batteries are not being used, they will not drain as fast as a normal NiMH battery will.
Have an almost fully charged battery even after months of idle time
Very popular for microphones, clocks, smoke detectors, and more.
Can be recharged at least 500 times so you can save money on replacing hundreds of disposable Alkaline one-time use 9V batteries
Should you buy Tenergy PREMIUM line or CENTURA Line? (This package comes with Centura)
Buy Premium if:
You will use the batteries frequently and they will not sit idle for long periods of time
You need longer run time and higher capacity
Your device is high drain (cameras, radios, game controllers, etc)
Buy Centura if:
Your device doesn't require high drain and can last for a long period of time (clocks, alarms, smoke detectors)
The device or batteries are more idle than used

The packaging and products build quality are first rate, as good as name brands like Energizer or Duracell.
It not only shuts off based on reaching the final voltage, but has a backup timer to prevent overcharging. Out of box, the batteries top up in < 1 hour, and this was confirmed because I did it 4x, one for each battery. On a depleted battery I had at home it was fully charged in under 2 hours. It does not get hot to touch. It works as described with the LED being RED when charging, and turning green when charge completed. The charger is very small and pocket sized.
9V batteries are made of multiple cells in series, it can have 6,7,8 giving a final voltage of 7.5, 8.4 and 9.6Vdc. Cheaper 9V use 6 cells, and the benefit of having more cells is that often devices powered with 9V batteries turn off when it detects low voltage, so more cells mean the battery will last longer in use, even with the same mAH. The end charge voltage of these cells are 9.7V, so one can be sure its anything but a 6 cell 9v.
I was skeptical whether these batteries were truly low self discharge. Its been about 1 mo since I charged 3 tenergy batteries and one new standard NiMH 9V together, and after this time, the standard NiMH has self discharged to 8V while these cells are still 9.7V!
I've been using one of the tenergy in a multimeter, and surprisingly it still reads full after over a month of use. When used with a 6 cell 9v NiMH it will register 50% in 2 weeks.
Update; A year later these batteries are still going strong. By now they last for months at a time in my fire detectors. I'm still very pleased.

Batteries are great. They can sit for a month and not loose their charge.
