Powerex MAHA Wizard AA/AAA NiMH/NiCad Intelligent Battery Charger/Analyzer: � Four independent slots...
It's like having four charger-analyzers for AA and AAA NiMH / NiCD batteries.
� Large backlit LCD display...
Digitally displays capacity, voltage, time and current.
� Endless programming possibilities - over 10,000 ways!
29 selectable charging and discharging rates. Charging current from 0.2A to 2.0A and discharging current from 0.1A to 1.0A in 0.1A increments.
� Five modes of operation...
Charge: Recharges the battery at the selected rate.
Suitable for batteries used frequently.
Refresh & Analyze: Charges the battery, rests for one hour, discharges, rests again, then recharges again. Selectable charging and discharging rates.
Suitable for batteries stored for more than two weeks but less than 3 month or those showing poor performance.
Break-In: Also known as IEC capacity measurement and "Battery Forming". Charges battery at 0.1C for 16 hours, rest for one hour, discharges battery at 0.2C, then recharges again at 0.1C for 16 hours.
Suitable for new batteries and those stored for more than 3 month.
Discharge: Discharges the battery at the selected rate.
Cycle: Performs charge-discharge cycle for up to 12 times with discharge capacity stored in memory. Recharges battery after final cycle.
� New ways to take care of your batteries and maximize runtime!
In most devices, usually two or more batteries are used together. When batteries are used in a series, the performance is limited by the worst battery. In other words, one poorly performing battery can significantly reduce the device runtime.
Battery matching refers to grouping batteries with similar �actual" capacity. To perform this, use the Refresh & Analyze mode to determine the battery capacity. Group batteries with capacity within about +/- 5% of the rated capacity.
New batteries and those stored for extended periods become chemically deactivated. Battery forming is a charge-discharge-charge cycle which forces a full charge into the battery at a very slow rate. This process activates the battery. In certain cases, it needs to be repeated two or three times. Battery forming can be performed using the Break-In mode.
� Delivers just the right charge...
Independent negative delta V, temperature and timer protection eliminates over and undercharging.
� Super light travel worldwide power supply and 12V compatible.
Batteries not included.
