Charge Marker, the manual battery indicator. Originally designed in 2011 and now helping thousands of users keep track of their battery charge status!

Charge Marker is a quick, simple, visual gadget that permanently adheres to your rechargeable battery to help you keep track of its charge status – no connections, no fuss!

Operation for Use:

Once your battery is charged simply slide the manual slider to green to indicate that the battery is ready to use. When you have discharged your battery slide the slider to red to indicate that it needs recharging. It’s really that simple!


Choose an appropriate location for the Charge Marker on the battery.*
Make sure that the selected battery surface is relatively flat (it is not recommended to mount on batteries that only have cylindrical form).
Ensure that the selected surface is clean i.e. free from dust, dirt and oils.
Remove the adhesive backing and apply to battery, pressing down firmly and leave for one hour before use.
