In-Cell Charge Control

In-Cell Charge Control or I-C3 is a method for very rapid charging of NiMH batteries, patented by Rayovac. Batteries using this technology are commonly sold as "15 minute rechargeables".

Weighing the right way

The charge control consists of a pressure switch built into the cell, which disconnects the charging current when the internal cell pressure rises above a certain limit (usually 200 to 300 psi or 1.4 to 2.1 MPa). This prevents overcharging and damage to the cell.
