The Duracell 2 AMP Battery Maintainer is ideal for keeping inactive batteries (such as those in an extra vehicle, boat or RV) charged up and ready for instant response by providing safe, steady maintenance charging between uses. It's built to withstand thousands of charging cycles and can stay safely connected for long periods of time without overcharging your battery. It is portable, lightweight, easy-to-use, and includes an accessory package to suit most types of battery connections. The Maintainer connects quickly to your battery via easy-to-use clip plugs, DC lighter plug or ring terminals to provide a complete charge of all internal cells.

Rapid Charge Technology for Faster Charging
The Duracell 2 AMP Battery Maintainer is part of a family of ultra-compact, light weight and modern power inverters and chargers from Battery-Biz Inc. The Duracell line of Battery Chargers features rapid charge technology for faster, more accurate charging, and do not require installation or set up. The simple plug-and-charge solution makes these chargers ideal for extending and recharging all types of 12-volt lead acid batteries. The three stage charging process ensures the battery is always fully charged, but never overcharged.
Duracell Battery Chargers utilize a microprocessor-controlled three-stage charging method which significantly extends the battery life. Multistage charging ensures that batteries receive optimum charging with minimal wear and tear by regulating the voltage and current delivered to the batteries in three automatic stages: Bulk, Absorption and Float. The bulk charging stage replaces 70-80% of the battery's state of charge at the fastest possible rate. After that the absorption charging stage replenishes the remaining 20-30% of charge, bringing the battery to a full charge at a slow, safe rate. Finally, at the float charging stage, the voltage is reduced and held constant in order to prevent damage and keep batteries at full charge.
Complete, continuous charging in three stages that is safe for your batteries.

Key Features
- Extends the life of 12-volt batteries in ATVs, snowmobiles, motorcycles, cars, trucks and is ideal for deep-cycle RV and boat batteries
- Ensures that your vehicle battery will always be charged up and ready for use
- Micro-processor controlled three-stage charging provides a truly complete battery charge and extends battery life:
- Stage 1: Initial Charge - provides the bulk of the battery's power
- Stage 2: Absorption Charge - ensures a full charge of all of the battery's cells
- Stage 3: Float Charge: Steady "maintenance" charge prevents the gradual loss of power that occurs in occasionally-used batteries
- Can stay safely connected to your battery indefinitely for maintenance charging
- Three types of connectors provided with the unit allow easy connection and charging via clip leads, DC lighter plug or direct-connect ring terminals
- "Plug and play" charging solution; requires no installation or setup
- 2-amp constant DC output current

* Three-stage charging
Multistage charging ensures that batteries recieve optimum charging, but with minimal wear and tear regulating the voltage and current delivered to the batteries in three automatic stages: - Bulk - Replaces 70-80% of the battery's state of charge at the fastest possible rate.
- Absorption - Replenishes the remaining 20-30% of charge, bringing the battery to a full charge at a slow, safe rate.
- Float - Voltage is reduced and held constant in order to prevent damage and to keep batteries at a full charge.
** Reconditioning
Battery reconditioning is a deliberate overcharge designed to return all cell to optimum condition condition by reducing sulphation and stratification in the bettery. The overcharge helps the battery to reach and maintain peak capacity by equalizing the chemistry in the individual battery cells.
