FAQ
Can I mix AA, AAA, C, and D batteries at the same time?
Yes — the 8 independent charging circuits handle any combination of sizes and any count from 1 to 8.
When should I use Soft Charge instead of Rapid?
Soft Charge (1000mA) minimizes heat and stress to extend battery life — best for everyday top-ups. Use Rapid (2000mA) when you need batteries back fast.
Can it revive old or underperforming batteries?
Yes — the conditioning mode charges, deep-discharges, then recharges automatically for maximum rejuvenation, and can identify defective cells.
Can I use it while traveling internationally?
Yes — the included heavy-duty AC adapter accepts 100–240V, 50–60Hz worldwide. No car adapter support, however.

Just got yesterday and It works great. not only did it charge my C and D batteries. but I tested on 4 survival frog A.A battery's. charged in usp port light turned blue and only at .87v. put in this charger and it came up to 1.35v. D's took awhile as rated at 12,000 mAh. my old charger was charging at 500 mAh and really took forever

Serious All-Sized battery charger for the serious user....
Posted by Jim Adams on 8th Jan 2019
Serious All-Sized battery charger for the serious user of rechargeable nickel-based cells. I got pretty tired of the 25-$30 crop of 8, 12 and 16-bay chargers that progressively reduce both Charging current and Refresh Discharge current as you load up the battery bays - for no obvious or technical reason. The AC/DC adaptor is large enough to handle 8/12/16x the advertised charging current for AA and/or AAAs. There's no noticeable charger heat but the charger won't do it. Discharging takes near-zero power but the charger will reduce that current per bay as you add cells to the available bays. Same with charging. Silly and measurable. And is why a full-boat set of AA or AAAs may literally take a day or more for a "Refresh" cycle. I have the no-nonsense, not cheap Maha PowerEx MH-9000 Wizard 4-bay charger/analyzer so thought I should finally spend the money on this thing vs. wasting $ and time on chargers for children.

Going strong since 2010 under almost daily use
Posted by J. Fish on 4th Jan 2019
Bought this charger in 2010, and it's still doing a great job. I primarily charge Eneloop, Tenergy, Canon or Energizer NiMH AA's, AAA's and a few C's. This charger's "conditioning" cycle has brought back numerous batteries other chargers wouldn't even recognize. And the "soft" cycle (which I often use in conjunction with "conditioning") is a nice feature that (to this non-techie) would seem to take better care of your rechargeables. In the first few months, it took a bit to learn the several features of this charger... but now it's all second nature. The power brick for this is a bit large as I'm sure other reviews have mentioned, but that doesn't bother me. I have this set up in a "permanent" place so it's always convenient to charge a battery (don't you always need to charge a battery like I do?). Since I purchased this in 2010, there are undoubtedly newer, possibly less expensive chargers out there, but if I had to replace this charger tomorrow, I'd go straight for it again. It proves itself every day as a great investment.
