do i have to charge all 4 batteries at once or i can just charge 2?

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.

That will depend on your charger, and not on your battery. However, you should usually charge batteries of the same kind -- not mixed.

If you have a charger that is designed to charge two batteries at a time, then you can charge any two of these batteries. Most chargers will charge at least a minimum of two batteries.

I would either charge them one at a time or buy the 2611A Dual 5/5A charger. I am guessing it has an isolator built into it to keep the batteries separate. Two batteries being charged from the same source need to be separated by an isolator. I had to buy an Isolator Kit for my boat engine so it could charge both batteries at the same time. I use this one for the Battery that runs my trolling motor on a different boat.

Don't think it really matters because in balanced charge mode (I use every time) when one cell reaches 4.20 it will keep charging the others till they hit 4.2... But you must use matching battery's... Same mAh and cell count.... So if you have 'two' 2cell 5000mAh battery's you would charge them at 5.0v coz there both 5000mAh and you would have 4cells in total so choose 4cells on ya charger.. Hope this helps...

When you want to use a three bank charger to charge only two batteries simply connect two sets of leads to one battery.

Absolutely, my batteries are the size of electric wheelchair batteries which are made to run all day without a charge. I charge 4 at once. I use a smaller charger (same Make) to charge my car battery. I would recommend this one because you can select a trickle charge first. Too much charging will ruin your battery. even 6 amps is not excessive.

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.

it comes with it's own charger so you can charge 2 batteries at once and your existing chargers should be able to charge them

It depends on your "charger" not on the battery. The charger that I use allows me to charge one or up four batteries at a time.

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.

Yes, but would have to ask, why 2 charge controllers to 1 battery or battery bank ?

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

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.

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.

From the operating instructions: The i4 features four charging slots, with each slot able to charge batteries independently. Rechargeable batteries of differing chemistries and and voltages may be charged simultaneously using 1,2,3 or 4 of the charging slots. ( Only charges 3.7v LI-ion or 1.2v Ni-Mh/Ni-Cd rechargeables.)

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.

the instructions state the batteries should be charged in pairs vs alone, as closely matched as possible in type/size, and if only 2 batteries are being charged then in slots 1 and 3 or 2 and 4.

You can do either of the two. You can charge one single battery, or charge two batteries simultaneously. It does not matter at all.
