Rechargeable Lithium Battery
Handle
Taking advantage of new battery technology, the Lithium Battery
Handle provides you double the on-time in a smaller and lighter
weight package. Smarter battery technology means that
"memory" is no longer an issue. What's more, the Lithium
Battery Handle can remind you to recharge with its low battery
indicator. The soft rheostat section provides a sure grip and the
overall design is ergonomically sound. The charging base and
charger charges the handle in 14 hours.
Before using this product, please read the following warnings
and instructions.
