The ideal 8.4 Volt replacement battery compatible with your 9V NiMH batteries. The lithium-polymer or Li-ion technology impresses with its high energy density, high capacities, and very low self-discharge.

Li-7.4V-650S 9V block 6LR61 6F22 650mAh

Li-ion or Li-polymer battery ReadyToUse with PCB protection. PCB for short circuit, overcharge, and deep discharge protection. You can use the Li-Po battery just like other batteries in almost any device, without the usual, often high self-discharge. Since this battery uses lithium technology, a special Li-ion charger is required for charging. We recommend the charger LI-V1.
