The voltage range of 9V battery varies with different kinds of materials:
9V Li-ion battery working voltage range is 6V-8.4V;
9V NiMH battery working voltage range is 7.2V-8.4V;
9V Alkaline battery working voltage range is 6V-9.6V;
So our 9V Lithium-ion rechargeable Battery Voltage Range is 6V-8.4V.
Note: The 9V lithium ion batteries can used for any devices which need standard 9v batteries. If your device needs a voltage higher than 8.4v, we advise you buy Alkaline 9V battery.

Feature:
