How many batteries can you charge at one time?

You can charge two batteries at one time. The picture is very misleading. The picture appears that the four batteries are actually connected to the charger but what you are seeing in the picture are the four batteries touching the side of the battery charger.

Yes, it will just take twice as along if both batteries are in the same state of discharge. Depending on how your two batteries are hooked up you may be charging both anyway.

(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.

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.

Sure! It all depends on the condition of the batteries and how fast you want to recharge them. If they are not all the same age and charge level you might want to charge them separately.

If you have an appropriate charger to accommodate all four at once, go for it. If not, charge one, two, three at a time. My charger allows all four at once, or otherwise. Even allows charging of different sized rechargables ! Read the specs on your charger, as I'm assuming that yours is like mine.

Yes you can sharge 2 lipos at the same time, or 1 lipo and 1 NiMh, as I ofter do. Brands of batteries don"t matter, just type, and size. Charger works great!

Because the battery charges inside the Scooba, you couldn't actually charge 2 batteries at the same time, but you could charge 2 within a 24-hour period, maybe even a 16-hour period--charge battery #1, swap it out & charge #2, run a cycle with battery #2, swap out to battery #1 & run a second cycle.

No. Batteries have to be in sets of two, so you would need another battery to bring total to four. Or do two until charged, take one out and put in the uncharged one leaving in one charged battery. I know its a hassle, but Amazon Basic charger works the same way.

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 will charge one at a time but it can charge pretty much any batteries you have. It works for all types and scales of batteries. Hope this helps.

Yes, although I would parallel no more than three. Also, if the batteries are of differing ages, it's not a good idea, as they will respond differently to both charging and pulsing, and a defective battery may load a good one. In general, batteries charging in parallel should be isolated from one another by a diode in series with each battery. This will reduce the charging voltage slightly, and thus will extend the recharging time.

It can charge 4 AAA/AA/C/D batteries at a time in any combination. It can also charge 2 9 volt batteries at a time I've used it with AAA/AA & C s with no problems.

Ah! So you are saying that if charging 1,2, 3 or 4 batteries, it is best to place one in each channel - NO in pairs. Thank you for the clarification.

I'm not sure what n-cells are, but it can charge four D-batteries at once. It can definitely charge a AA and AAA at the same time. There is a port to charge a 9 volt battery, so if you were charging 4 AA or AAA, you might be able to charge five batteries at a time.

It depends on the battery type. We mostly charge AA. We can fit 2 AA in each slot, 4 slots totaling 8

you can charger the low batteries one at a time until you get about 25 to30 volts. then hook up your charger to test it out.
