how many AA batteries can it charge at once
1424059
I have not used it to charge AAs but the picture in the manf's brochure indicates two and it makes sense. The batteries are place in the unit - one in one direction and one is the opposite direction. One battery is at the positive pole of the charger and the other at the negative. I've been using it to charge camcorder and camera batteries and it is working fine - seems a little flimsy but that was a common comment about all of the chargers when I was picking the one to buy. Good luck. I think the "flimsiness" is due to the many different size/shape batteries it will charge.

(4) Four 18650 batteries of different capacities can be charged at once. It is a two bank system so 4 cells will take about twice as long as 1 cell to fully charge.

If your 1amp charger is 12 volt AND you charge the batteries 1 at a time. I use my 2 amp charger from time to time.

Hello. You are correct. It charges 2 at a time. I think its a fantastic charger/battery set at this price point. Hope this helps.

It uses four AA batteries at 1.5 volts each or 6 volts total. You can, if electrically inclined, fabricate the proper connector and use a universal power supply.

Not sure I understand the question, but if you mean can it charge two batteries at the same time, the answer is no. That said, it charges quickly and it has not been a problem doing them one-at-a-time. Great charger!

It can charge up to 4 batteries at a rate of 6 amps each. A 20 amp could do the job if you are not charging 4 packs at full capacity at once. A 30 amp power supply is a safe place if you are going to charge multiple batteries at once. Here's a good 20 AMP supply. Racer's Edge 20 Amp, 13.5V DC Dual Output RC Power Supply with USB

The charger can charge either AA or AAA sizes and either in a pair or all 4. I ordered mine with 4 AA, this was my need.. But if I recall you may be able to order either, confirm this... I have since ordered additional batteries just for extra.. The charger itself is good, and charges in typical time - its not a quick or fast charger.. But good for overnight. It comes with other plugs for different countries although I dont forsee a need in my future, but hey... I gave more info than requested in hopes it answers any other or others questions...

I don't know, sorry I cannot answer that, however I am sure it is safe to charge 2 batteries.

It can charge any combination of batteries. The smart feature senses the battery and optimal charge level in each slot independently. I charge AA and AAA together all the time.

Yes, it can charge one AAA, one AA, one C, and one D if you want at the same time. If you just have one battery that needs recharging, you can do that also. I love this charger. I've had it for about a year and it been great.

The unit will charge any combination of one to eight AA and/or AAA NiMH batteries, regardless of mAH rating. Mix and match - the charger doesn't know and doesn't care.

In pairs. There are four "cells", which can hold two AAA or AA or one D. AAA ans AA must be charged in the same cell.

I have owned this. The universal charger WILL charge batteries individually. There are 4 charging 'points' and you can choose to put one small battery (AA or AAA) in one point. Of course, you can also put two small batteries in each point to get the full 8-at-a-time figure. This also only applies to the small batteries. Cs and Ds are charged individually in each point, so their max is only 4 at a time total.

I have only charged AA batteries and it does great with those. I have not tried AAA batteries yet.

It charges 2 D, 2 C, 2 AA, 2 AAA at a time and 1 nine volt battery at a time. I just bought this unit and am testing it now. One thing I don't like already is that the indicator lights are on the front where, in the bright light of the sun it is difficult to determine if the light indicating it is charging...is actually on. It does seem to be blinking red very fast but very hard to see. I will review it thoroughly once my testing is completed.

It will charge 2 @ AA or 2 @ AAA or one of each.....but not a single battery of either type: only 2 at a time.
