Rechargeable 9V 550mAh Lithium-ion batteries
This is not a 9 volt battery. These are all 7.2 volt batteries. Most solid state devices, including DVMs and other test equipment will not operate on this low voltage.
9.0 volt rechargeable batteries are available. This type of battery contains 3 cells in which the chemistry has been modified to produce 3.0 volts per cell. I have several of these.
Do NOT buy these batteries if you desire 9 volts!!!
Indicator lights is useful.
