IMPRES batteries, when used with an IMPRES charger, provide automatic, adaptive reconditioning, end-of-life display and other advanced features. Data is stored in the battery and communicated to the charger via a unique IMPRES communication protocol designed to maximize talk time and optimize battery cycle life -- all automatically. This 1700-mAh NiMH IMPRES battery is rated intrinsically safe.

Battery Care and Tips
These battery tips will help you obtain optimized performance
and a longer life cycle from your rechargeable battery.
- Charge your new battery overnight before using it.
- When using a rapid charger, leave the battery in the charger for an additional 1 to 2 hours after the green light appears.
- Only charge a battery when it needs it. If it is not fully discharged, do not recharge it. We suggest that you carry a spare.
- Do not return fully charged batteries to the charger for an "extra boost." This action will significantly reduce cycle life. Repeated short cycle charging of batteries will shorten battery life.
