intelligent battery charger
Unlike most other "dumb fast chargers",  you can finally safely rapid charge your AA, AAA, C, and D Nickel Metal Hydride and NiCD rechargeable batteries regardless of capacity! The microprocessor checks the voltage (-V and +V ), and terminates the charging process and then switches to trickle charge automatically. With the MW-5798 PRO's intelligent microprocessor design, your batteries will be at their peak performance at all times. The AT-5798 PRO charger uses a pulse charging technique, which will provide a PWM constant pulse current during the various charging stages. Charge time varies with the size, capacity, and charge state of the batteries when put into the charger. Plus you can simultaneously charge two 9V NiMH or NiCD batteries - Yes at the same time. (9V batteries are charged at 13mA with manual control)

battery conditioning
 The added conditioning capability of the MW-5798 PRO will help maintain your batteries best performance automatically each time your batteries are charged. User intervention is not required for standard conditioning, since this is automatically cycles each time any batteries are charged in either the right or left bank. Another great feature of the AT-5798 PRO charger is its built-in discharge and deep conditioning function to ensure all your batteries work at their optimal conditions. This feature was designed mostly for rechargeable batteries such as NiCD batteries which often require a discharge/deep conditioning cycle before charging in order to break the memory effect that NiCD batteries often exhibit and help rejuvenate your batteries to their best performance. This built in discharge/deep conditioning  function can be activated at any time simply with the push of the discharge button and operates on the left bank. ( Left Side ).

dual charging circuits
The intelligent MW-5798 PRO features two independent banks, able to perform different functions simultaneously. This means you can charge two unique sets of two batteries. You can put two NiMH AA in one bank and two NiCD AAA in the other bank or even two C or D size batteries, all automatically.  Plus you can charge two 9V batteries at the same time.  IT'S LIKE HAVING THREE CHARGERS in ONE!

use in mobile & car 
Operate the charger in your car, boat, RV, or any 12V power source with the optional 12V power cord.

MW-5798 PRO KIT

Picture above and left shows the AT-5798 PRO charging 4 AAA size NiMH and two 9V batteries.  Each outside channel has LED indicators that glow red while charging either AA, AAA, C , or D size batteries. The LED changes to green when your batteries are charged and the unit has switched to trickle mode.  The 9V Batteries have an LED that glows red while 9V batteries are being charged.

RAPID CHARGER
This state-of-the-art charger can rapid charge your NiMH ( Nickel Metal Hydride ) and NiCD AA / AAA batteries with the precision that only microprocessor technology can provide. Designed with two independent circuits. You can charge either one or two sets of batteries totally independent of each set.

DISCHARGE/ DEEP CONDITIONER
When using different types of rechargeable batteries such as NiCD, they often exhibit memory problems. With the conditioning features available in the AT-5798 Charger your batteries can now be revived from poor performance. In addition the  AT-5798 PRO battery charger can condition one set of two batteries while charging another set. Once the conditioning cycle is complete the unit switches to the normal charge cycle. Totally automatic.
