topping up the water after each battery recharge

The system also includes a battery charging module that mates with the mobile robot battery plug module, and an alignment system that aligns the battery plug module with the battery charging module.

Preferably the charger can apply two modes of charging a battery. n a normal charging mode a battery is charged to full capacity at a low rate.

A battery charging assembly (30) for charging a battery of a mobile device includes a charging unit (34), an output assembly (36) and an input assembly (38).

Temperature compensation methods and equipment for charging electric storage batteries are described.

A battery operated motor system (70) includes a rechargeable battery (18), a motor (16) and circuitry for recharging the battery.

There is provided a planar inductive battery charging system designed to enable electronic devices to be recharged.

The present invention relates to a method and circuit configuration (100) for preventing any needless battery recharge at each short battery voltage dip.

A battery recharging apparatus (102) is specifically configured to enable a customer to exchange a discharged or partially discharged battery for a fully charged replacement.

A cycle is the equivalent of using 100% of the battery.

My problem is the battery charger is no longer working.

Two lighting systems with the possibility of replacing the batteries

This invention is about advanced version of recharging battery (6) for electric car.

The battery modules may also be aligned with the aid of video images of the battery charging module provided to the remote station by a camera located within the battery plug module.
