Rated 2 out of 5 by from I have had several Maplin chargers for their own NiMh batteries and the only one that has worked reliably was the first one I bought years ago, the only problem with it is the length of time it takes to charge 4 AAA batteries - 3 hours or more. This smart charger does the job in around an hour, but if and only if, the batteries are not completely flat. I have some portable Ipod speakers powered by 4 AAAs and sometimes I forget to turn them off and some hours later they are drained to the point where this charger refuses to charge them saying they are "BAD". A short charge on a less sophisticated charger enables them to charge perfectly well with this charger, but of course that means I have to carry 2 chargers with me, not exactly ideal. I bought a new pack of Maplin AAAs and of the 10 in the pack initially this charger would not charge 4 of them. I scrapped many rechargeable batteries in the past because the last Maplin Smart charger said they were no good and this one is no different. So be warned these smart chargers are very sensitive to battery condition and any abuse at all of the batteries, intended or not will mean that this charger rejects them. With all the money I've spent on chargers and mistakenly recycled batteries, two things come to mind. One I'm probably not saving any money over Alkalines and the other is I could have spent Ј70 on a professional charger which may be better and saved several dozen perfectly usable batteries from being recycled.

Rated 5 out of 5 by from This is a great little charger. I got it because it can charge 1-4 batteries, it's size and charging speed. I use a lot of batteries and when I'm at my dads place I can't charge batteries too quickly with his charger. This charged my 2850mAh batteries in under 3 hours. It will tell you if your battery is a dud and it has a little display that will let you know how much of the battery is charged. I'll be getting another one because dad has claimed my one!

Rated 1 out of 5 by from Very Disappointing and Erratic Performance I have 24 2600mAh AA batteries which are mainly used in a camera that drains them fairly rapidly (about 60 shots from a fully charged pair). Fed up with having to wait 14 hours to charge four batteries I decided it was time to get a smart charger that could charge 1/2/3/4 batteries quickly and was small enough to take on holiday. At first this one seemed to be just the job. Put four batteries in, it displayed approximate charge level of each ( some low, some hardly discharged) then started charging. After about 10 minutes the charger indicated that one was fully charged then, over the next hour or so, the others indicated one by one that that they were fully charged. In use, however, the batteries didn't seem to last very long (sometimes only 2 or 3 shots and occasionally the camera would say "change batteries" as soon as it was switched on). Over the next few months this pattern repeated itself and I assumed that the batteries were nearing end of life. A few weeks ago one of our cordless phones was dead (hadn't been put in base unit properly and the 800 mAh AAA batteries were flat). Put them in this charger to give them a boost and after 10 minutes it said both were fully charged. However, on reinserting them the phone's battery level indicator showed that they were at the minimum of 4 levels and it took a couple of hours on the base unit to get them back up to maximum. After extensive testing using the same 4 AA batteries and measuring voltages and current delivering capability I discovered that only one of the charging bays gave a decent charge. One gave hardly any charge at all before indicating "fully charged" and the other two fell somewhere between. The old "fixed low current for 14 hours" charger consistently fully charged the same 4 batteries. Maybe this was a one-off dud but be warned. Also, in common with all "smart" chargers that I've read about, if a battery is really flat (less than about 0.75 volts) this one just says "bad" and won't even attempt to charge it. However, stick it in an ordinary fixed charging current charger for a few minutes to raise the voltage a little and the smart charger will take over quite happily (albeit erratically in my case).
