T4 Test charger

Test function that is very useful as it allows you to run a charge/discharge cycle on your battery & display the actual MA rating of the cell.

Has a 5v usb socket so can be used as a charging dock for mobile phones/Tablets etc.(requires a charged battery to be installed)

will charge almost any capacity of Ni-MH/CD and Li-ion battery

Back lit LCD display showing loads of battery info on each cell
