The problems of traditional batteries, NiCd or NiMH batteries, they have average voltage of 1.2 V. This way when you replace batteries 1.5 V Rechargeable not already start with tension 20% minor. Various equipments adapt to this difference, but most have difficulty functioning properly. Like this, When the voltage of a rechargeable battery reaches 1V equipment crashes, Although there is still enough load to be used.
The LiFePO4 batteries are a solution to this problem. The tension is 3.2 V and are suitable to replace two common batteries. You must then place one of these and a stack dummy to 0V, so that the total of two is 3.2 V.
This package comes with 4 LiFePO4 batteries size AAA (also known as 10440). The voltage remains above 2.6 until the battery reach 0%. Like this, most of the equipment will work perfectly since 100% to 0% of load.
It also comes with manual. The stack dummy It has to be purchased separately.
Below the battery with the battery Tester. The voltage is 3.3 the 3.4 V when the battery is fully charged.
I'm testing this battery with toys, remote controls and other devices and the result is fantastic. The durability of a common rechargeable battery was one to two weeks, While these cells last for months and months. They work from the maximum load to a minimum. Need, However, of a special charger and of stack dummy.
