Lithium Charge Rates

Most lithium batteries should be charged at rate of 1C or less, as a rule of thumb. Some batteries can do higher charge rates, but its harder on them - so if you keep it under 1C they will have a good long life.

A C-rate is a measure of the rate at which a battery may be charged or discharged relative to its maximum capacity.

For example, a 1C charge of a 90mAh cell would be 90mA

A 2C Discharge of a 90mAh cell would be 180mA ( 2 x 90 = 180 )

A 10C Discharge of a 90mAh cell would be 900mA ( 10 x 90 = 900 )

And so on... It's pretty simple really.

So in a nutshell, all you need to do is set the charger to a rate less then or equal to the indicated capacity. Most of our batteries have their Max Discharge rate marked on the cell with the part number. It is also listed in that products webpage.
