Most Revos are very reliable and only a few users experience problems with battery life. This Information is provided for the unlucky few and those who want the very best life from their Revo batteries. I've heard quite a bit of misinformation about the Psion Revo with regard to the batteries and decided to post this information to clear up a few issues. The Revo is equipped with two AAA NiMH rechargeable batteries and an internal charging circuit. This circuit is fed by a 6V DC adapter, usually by the docking port.
Sound is available until the 'Recharge' message appears.
Contrary to popular and nervous opinion, the Revo charging circuit is a precision piece of kit and uses purpose-built charging ICs designed by one of the world's leading battery manufacturers. However, to work properly, it is vital that the user follows the first charge instructions to the letter. The first time the Revo is charged from new, or after a hard reset, the charge controller senses a chemical change in the cells. This is a feature of NiMH cells. We'll call this the charge calibration point.
