Does it expect all batteries inserted to have the same charge and charge them as a group, or does it charge each battery individually?

This charger is slower than others (overnight charging, not 2 to 5 hours like some), so it is probably a trickle charger feeding the same charge voltage to each battery.

You can carge up to 8 at a time and they all have the same charge. I haven't had any problems with the charger. It just depends on the batieries you get for it. You can charge aAA's and AA's. If you have any other questions feel free to ask.

The charged amount of the batteries doesn't matter from my experience. They charge as a group, I believe. I've had no problems with NiCD's overcharging.

It will charge 4 x AAA at once. OR 4 x AA at once. OR 2 x AAA AND 2 x AA at once.

No, the simple display shows 4 "batteries", each represented by an icon with 4 bars. It shows the charging/discharging progress by how many bars are present, with 4 bars being full. If charging one battery, when the battery is full, it will say "Full". If charging multiple batteries, it was say "Full" only when ALL the batteries are completely charged. You can NOT charge one battery and also discharge another battery at the same time. It's either charge or discharge. So, it's a pretty simple charger without a lot of bells and whistles, but for the price it does what it's supposed to do, and I'm still quite happy with mine.

The outputs are completely separate of one-another. It's recommended that you charge each battery independently of one-another. Please let us know if you have any further questions. -ServoCity

If you look closely in the slots the aa batteries fit into you will see some short tabs that aaa batteries will engage. They will not be obvious in a picture unless it is a closeup. I thought the same thing and thought it was kind of cheap but it seems to be a clever way to charge both aaa and aa batteries in a compact design. I have been using mine primarily for charging aaa batteries for a headlight I use everyday at work and have had no problems.

It will charge singles, up to 4 batteries. I don't know about N-cells it doesn't look like it will go as small as N-cell. Yes it will charge different sizes at the same time but not different types, such as Ni-cd and Ni-mh at the same time because you have a switch to move to change from each type. DO NOT CHARGE regular alkaline batteries in it , THEY WILL LEAK. I have to take mine apart and clean the insides of it from batteries leaking in it. Hope this helps,Mike

Read the product description it tells you what all batteries it will charge.

You have to choose the battery type you are using and then it will start charging. Yes, everytime you connect it, it will want you to choose.

It's the same as any other battery - depends on how much you use it..! It's a battery that gets its own charge from the solar panel then charges other batteries. If you do a lot of battery recharging, then you'll need to keep it topped up (ie, solar charging).

I put in two seperate ones with the charge controllers one for each battery, the charge controller has two indicator lights on it one for charging and one for charged otherwise I couldn't tell if it was working, a little expensive but they do work

You can charge a single battery if you want to as each battery holder is more or less a separate charger.

You can charge uneven amount batteries but there is no green signal shown (it means the battery is fully charged) for the single battery charged.

As far as I know, they automatically charge when the batteries are put in the main part. They lit up as soon as we put the batteries in.

Because two batteries charge at close to the same rate, and are not identical in their depletion, the charger stops charging the first battery that's full, charging only the one battery that's left. Sounds like it should be able to do only one.

No, at least not with the one that I was shipped. The connectors where different (not as shown), so I swapped them out. Excellent charger though, it'll keep your batteries in tip-top shape for a long time.

Yes they do. You have to set each battery up for each wire so it knows what kind of battery it will be charging and they stay connected all the time. I have used this unit for over a year now and I think its great. When I get home from the lake all I have to do is plug the one cord in and all three of my batteries are charge in the morning when I"m ready to go again.

When you connect them like this, they operating in parallel - same as if you had wired the batteries in parallel yourself. Each battery will receive the same charging voltage. For some batteries, this this will be the correct charging voltage, However, the other batteries could be over-charged or under-charged. All the Battery Tender sees is one battery!This is answered on the Battery Tender website. The explanations are excellent, with clear diagrams. Find this info in the education section - it's a on pull-down tab, at the top of the homepage. A good reference for all battery charging and connection questions.
