12 Channel Smart AA, AAA and 9V Battery Charger with Discharge Function

Written by Vlad on March 19, 2011 – 10:12 pm - 3,824 views

Smart battery charger with discharge function, loaded with 8 AA NiMH batteries

This is a microprocessor-controlled battery charger that can charge up to 10 x AA/AAA batteries and 2 x 9V batteries. It supports both NiCad (Nickel-Cadmium) and NiMH (Nickel-Metal Hydride) simultaneously. Each battery is independently monitored and charged, and a multi-colour LED above each battery indicates the charging status.

There is a discharge function that drains all the batteries completely before commencing a charging cycle, which is useful for rectifying “memory effects” and other common battery problems. It employs several mechanisms to ensure that batteries are completely charged, but not overcharged.

It comes with both a 12V DC power adapter that operates worldwide on mains voltages between 100-240V as well as a lead that plugs into a car cigarette lighter socket so you can charge batteries when you’re on the road.

I purchased this from Jaycar electronics, who call it 12VDC & 240VAC Smart Battery Charger Ni-Cd & Ni-MH. I have seen similar smart chargers on eBay, but most are 10-channel chargers with support for only AA and AAA batteries.
