Great little charger.
|
Time owned: more than 12 months
|
I've had mine for quite a few years, since shortly after they came out. I've charged a variety of batteries, but my experience with this charger is limited to primarily Ni-MH (why would anyone want a NiCad now anyway). The ones I use most often are the Powerx 2300 mAh AAs and the charger does a great job of keeping them in top shape. I've got some new 2500 mAh Powerx AAs that I bought to replace the 2300s but the 2300s are still working "good as new" so I haven't need them. I use the batteries every day in portable radios (receivers). I have two sets for each radio and I cycle them every two weeks, recharging the ones that were in the radio and using the ones that were recharged two weeks ago.
I forgot to mention that my charger came with a clear dust cover over the battery compartment. You can't see it in the picture but it's there (unless MAHA dropped the cover on later units). DO NOT close the cover while you are charging batteries; it will trap the heat inside. Keep the cover open while charging and close it when you are done.

Should be called an "over-charger"
|
Time owned: more than 12 months
|
|
I have to retract my previous review: This unit pretty much destroyed NiCds I tried to charge with it. Bettery temperatures rise too hot to touch. I'm sure it's destroying my NiMhs as well, and I'm shopping for a better charger that has temperature compensation.

Good Charger

Time owned: more than 12 months

Only problem I have had is that it will not charge really dead batteries, I have to start the charge with a more conventional unit. Other than that it works well. TOM K8ERV

Excellent Value!!

Flawless operation. Great discharge feature. Haven't tried it with the 12V adapter, but with the supplied wall wart, it's dynamite!

Batteries get hot!
|
Time owned: 3 to 6 months
|
|
I purchased it as a mobile back-up charger for emergency operations. It seems to work well - but I am concerned about battery damage caused by high temperatures during charging. It heats batteries more than others I have used.

Easy to use
|
Time owned: 3 to 6 months
|

I use it with the new 1800MAH NiMH "AA" for powering cameras, flash units, and HT's. It never seems to charge batteries in less than 3 hours as advertised but it does charge them over night. Those new 1800 MAH cells seem to last forever. Buy the Powerex (MAHA) brand batteries. They work as advertised.

Good AA and AAA charger
|
Time owned: 6 to 12 months
|

Good cheap smart AA and AAA charger. No choice between slow and rapid charge, or between NiCD and NiMH - you just put the cells in and they go straight to 400-500 ma for at least a few min until the CPU figures it out, then to slow charge at 50-75 ma. (I measured this) NiCds get pretty hot if charged from fully down. Does not work with old marginal NiCds (this is actually useful for ferreting out dead or dying cells.) Has discharge-then-charge feature. Very little RF noise (forgot which freqs.) Runs off 12V wall wart or cig lighter. Small. I would recommend for NiMH and hi cap NiCds - buy 2 or 3!

Great Charger!

Time owned: 0 to 3 months

I just bought one of these today and used it to charge a bunch of NiCD batteries. Simple to use and it does a great job. The only thing more I could ask for is a unit that charges C and D size cells.

Best Charger I have had
|
Time owned: 6 to 12 months
|
I purchased this charger to recharge my NiMH batteries for kids toys. I also found a use in charging AA batteries for my HT. I found using 1600 mah batteries to last so much longer than the stock Nicad pack. the batteries charge from dead to full in about 3 hours. The charger knows when to stop since it only takes about a half to one hour for partially discharged batteries. I always have a fresh set to go. The only problem I see is the ability to only charge 2 or 4 batteries. This becomes a problem when you need three batteries.
The charger does not auto detect alkaline batteries. I was fumbling through the dark for batteries to charge and accidentally put in alkalines. the batteries made a pop noise and created a mess with a black liquid. I wiped and rinsed out the charger. The next day the charger worked again. I like this charger over the timed charger for charging partially discharged batteries.
I wish there were a charger for C and D batteries based on the same technology.
