[Q1] What's included in the package? Does it come with an AC adapter? DC adapter? Car adapter?
[A] The Maha MH-C9000 comes with an AC-to-DC wall adapter (100-240V AC input, 12V 2A DC output). It does not come with a car adapter, but that is a very generic CLA (cigarette lighter adapter) cable that you can find elsewhere. Just make sure its output is a 2.1/5.0mm barrel plug.
[Q2] Why is there a faint ticking sound coming from my charger during charging?
[A] The C9000 uses pulsed charging current at 50% 1Hz. When you select 1000mA setting, the actual charging current is 2000mA for 0.5 second, followed by 0mA for 0.5 second. That's why it emits a periodic ticking sound.
[Q3] What charging current should I choose for AA batteries?
[A] To recharge AA batteries on the Maha C9000, you can simply insert those batteries and walk away. The charger will automatically start charging at the default current of 1000mA. This corresponds to a charge rate of 0.5C for 2000mAh cells (1000mA/2000mAh = 0.5C), which gives a charge time of about 2 hours.

However, if you just want a simple, plug-and-play unit--or want to keep using some older (2+ yr old) cells--this is pretty much the worst choice you could possibly make.
The UI on this thing is just awful. For 3/4 of my older cells, it just kept cycling through the options even after I made charge/cycle/break-in selections. Basically it won't even try to do anything with most of the older batteries I have--like it doesn't even recognize them as batteries or something. For others, you'll get a "HIGH" reading which will put a stop to the unit also. At least with that reading the charger is telling you to toss them and/or it doesn't like them--but for most older batteries the thing doesn't say anything--it just stops and keeps cycling through your options over and over. That's ridiculous.
Basically this charger is "too good" and will literally turn its nose up at a LOT of batteries. So for most people that don't want a battery charger they really have to think about or wrestle with--this is an abysmal choice.
One last thing. Use any of those Energizer rechargeables that get all those near-5-star reviews on amazon? This will read HIGH and refuse those straight out of the box. Geeks say those suck and are useless. Are they? I can't say for sure, but this charger agrees and won't deal with them. Read online at the issues with this charger and those.
I can't recommend a unit that's this picky--at least without it telling you more about why it's being so.
When I got it and unpacked it my first instinct was that it is well built and should hold up for a long life of use. I have a good friend who owns the La Crosse BC1000 and when he showed it to me it had a not as well built feel to it. The body it self was OK but the buttons felt like they would wear out in no time. The second thing I noticed was how much bigger it was. I saw the pictures with the 2 side by side but until you have it in your hands its really hard to tell. As you can see by looking at the picture I added to the gallery it still fits well in my suitcase. Lucky for me though the c9000 is longer and wider it is still almost the same thickness. For those who are looking for the measurements it is 6.5in long by 4.25in wide and 1.5in thick. Some of this extra space is taken up by a very easy to read LCD. I am legally blind and though I have to press extra keys to toggle through all the info it is worth it as its so much easier on my eyes.
It is a fact that both the BC1000 and the C9000 do an excellent job in charging but I will say that when my friend and I compared the temps on the C9000 vs the BC1000 even with the Maha set to charge at 2000mAh it was much cooler than my friends La Crosse charging only at 1000mAh. With the C9000 having spacers between the batteries it would make sense but the BC1000 was hotter than another 30 minute charger we used to compare the temp with.Read more ›
