Greater efficiency with more power at considerably less weight: that’s Li-Power.
A Li-Power battery supplies around 96% efficiency, 16% more than NiCd or NiMH, as a result it can provide approximately 40% more energy than NiCd and NiMH batteries.
At the same time, it is around 40% lighter.
A battery pack with 18 V and a capacity of 2.2 Ah weighs approx. 700 g – a “normal” NiMH battery pack weighs just over 1 kg.
But that’s not all Li-Power can do: thanks to its lower self discharge rate, a Li-Power battery can be used immediately at full power even after a long storage period.
When you charge the battery, neither the memory effect or the lazy battery effect arise.
