Powerex MH-C980 Turbo Charger Analyzer for AA/AAA Batteries

I bought this one because I wanted a charger that could actually tell me if th ebattery was any good. Speed charges that came with the NiMH batteries tended to say the battery was no longer useful (for a speed charge) after only a few months. Great for the manufacturer, not so much for the consumer. I had to always go back to the slow charger that came with the battery (old school) because it at least apeared to charge the battery. This charger actually tells you how much charge (in mAh) EACH battery took. Simple comparison of that figure against the battery capacity, and you know if the battery works or not. First thing I did was to charge all the batteries I had using the Conditioner mode to see if they were recoverable. That takes 24H. Charger showed that 2 out of 15 were no longer useful. I highly recommend this charger. Really easy to use. Of the eight slots, each slot is handled like it own charger. Mix and match AA and AAA as much as you want. The charger keeps track of everything.

With this very electronically-based lifestyle many of us have adapted, I realized I was frequently buying new batteries for our remote controls, 'emergency' flashlights, etc. I no longer need to purchase new AA/AAA batteries after purchasing this amazing Powerex MH-C980 Turbo Charger Analyzer. I have the plastic containers of fully recharged batteries near my TV remotes and in my office. This. energy positive practice makes me satisfied that I am not wasting more natural resources but reusing what I have and saving money.

This charger has fewer settings than the Maha Powerex MH9000 which I also have, but it does the analyze or charge at both standard and turbo modes, the turbo being double the standard charge rate. This would only be useful if you need a lot of quick turnover. I typically use the standard charge or analyze. Be aware that the analyze function takes quite a while. I mainly use it overnight. Definitely a 5 star product!

Simple to operate, and does a great job getting your rechargeable batteries working as intended. If you have rechargeable batteries that will not hold a charge for long or will not power up your device anymore, then reconditioning your batteries is likely what is needed. It does take a while (18-24hrs) depending on the number or batteries and the capacity of the battery to be reconditioned. The fan turns on and is noisy only during the recharge phases. The display is useful to note the charge capacity of your batteries.

Great charger! A little noisy, as others have mentioned, but well worth the purchase price for the conditioning feature alone. I have a lot of old Energizer rechargeable NiMH batteries that I reconditioned after attempting an initial charge on them. My results were: Initial charge (AA batteries) on the Powerex MH-C980: Charged mAh (mfg rated mAh) 1. 338 (2000) 2. 318 (2000) 3. 299 (2000) 4. 343 (2000) 5. 1294 (2000) 6. 353 (2000) 7. 2975 (2500) 8. 1250 (2000) Reconditioning 1. 2200 (2000) 2. 2136 (2000) 3. 2225 (2000) 4. 2050 (2000) 5. 2095 (2000) 6. 2172 (2000) 7. Not reconditioned (2500) 8. 2109 (2000) I was pleasantly surprised at how effective the reconditioning was. My only issue with the charger was that the instructions did not say anything about how to insert AAA batteries into the charger. I must be a little dense, because it took me a while to figure it out. To recharge AAA batteries, you simply insert the negative end of the battery first (at an angle with the positive end of the battery up) and slide it until the negative end touches the smaller negative charging terminal and then push the positive end of the battery straight down to make the contact at that end. I was imagining that the negative terminals would somehow pop up to make the contact, but they do not. The little black button in each charging bay near the negative terminal is depressed when you insert a AAA battery, directing power to the AAA electrodes instead. Duh!
