Are you tired of waiting for numerous hours to have your batteries recharged? Do you have a collection of various sizes of rechargeable batteries? Would you like a charger than can discharge/recondition your ‘dead’ batteries? If your answer is a yes for the above, then look no further as this is possibly the only charger you will ever need.

  

The Intelligent Charger (IC) is a state-of-the-art, microprocessor controlled charger for charging rechargeable Nickel Cadiums (Ni-Cds) and Nickel Metal Hydrides (Ni-Mhs). It is able to detect the current state of the rechargeable battery and recharge it to the full capacity appropriately, irregardless of the brand and the capacity of the battery. It does this without overcharging or damaging the battery. –dV is used to control the charging of Ni-Cds while +dV is used for Ni-Mhs. Unlike conventional time-based chargers, it cannot be easily fooled. It will not charge batteries that are already fully charged. Overcharging will shorten the life cycle of a battery and may even cause permanent damage to it.

  

By pressing down on the switch in the center, the smoked cover springs up (damped action adds a classy touch to it) to reveal a well-designed battery compartment that supports AAA, AA, C, D (the 2 sides) and 9-volts rechargeable batteries (center). At any one instance, it can recharge two batteries of the same category. For the cylindrical rechargeable batteries, the IC uses a fixed contact point for the anode and a retractable contact point for the cathode so that it can accommodate all sizes ranging from AAA to D. Before proceeding further, here are the IC’s specifications: 

Input:

DC 12V 500mA

230/240V AC with AC/DC adaptor OR

110/120V AC with AC/DC adaptor

Charge Current:

PWM Constant Pulse Current – 800mA

Boost Charge Current:

1/2 Constant Pulse Current

Trickle Charge Current:

1/10 Constant Pulse Current

Discharge Current:

300mA

Detection:

dV, +dV

Type of Batteries: Nickel Cadmium (Ni-Cd) and Nickel Metal Hydride (Ni-Mh) AAA, AA, C, D and 9V

Unlike many of the usual chargers, the IC is equipped with a separate power adaptor. It means that this IC can be used practically in any part of the world, by simply using the appropriate adaptor. If you have an unused AC/DC adaptor that matches the above specifications, it can probably be used as well.

  

800mA is an impressive figure for the charge current specification. This is the highest figure I have ever come across for a cylindrical dry cell charger! It is a breeze to recharge batteries. As a reference, a table has been included in the operating instruction manual for an estimation of the charge time required. I have included the table for your reference. Check it out!

Try comparing the above charging times with your own existing charger and you will appreciate the difference. It can be seen from the table that 9V rechargeables require a notably longer period to charge. This is because the unit only uses a continuous trickle charge mode for charging 9V batteries. I was told that this is due to some technical limitations associated with 9V rechargeable batteries and they cannot be fast charged.
