Solder tail (Z), Low-self-discharge NiMH battery (ready-to-use), 4.8 V
The Tecxus "ready to use" NiMH rechargeable batteries are pre-charged and can be used immediately.
In addition to the low self-discharge rate, they are also environmentally friendly,
because they can be recharged up to 1000 times. After 12 months, the cells still have 80% of the pre-charged capacity.
