1. Introduction
The Duracell Ion Speed 1000 Battery Charger is designed to efficiently recharge AA and AAA NiMH batteries. This charger provides 4000 mW of charging power, allowing batteries to reach approximately 90% of full charge within 4 to 8 hours when using Duracell 1300 mAh or up to 2500mAh NiMH batteries. It supports charging of 2 or 4 AA and AAA NiMH batteries from any brand simultaneously. The included Duracell Rechargeable Pre-Charged NiMH batteries are ideal for high-drain devices such as video game controllers, wireless electronics, and baby monitors, offering hundreds of recharges and significant cost savings over disposable batteries. These batteries are pre-charged and ready for immediate use, maintaining their charge for up to 1 year when not in use and guaranteed for 10 years or 400 recharges, whichever comes first, and work in any NiMH charger.
