Will this isolator select the battery needing charging and only charge that battery so the other battery won't get over charged?

No, It will isolate the two batteries so the load on one is not seen by the other. Both will charge he same. However the lower one will receive more charge current then the higher one until they are the same. It will not harm any batteries when connected correctly.

No it does not, BUT i've had it for about 3-4 years now and have never had a battery over charge. ALSO one key factor when wanting to run a dual battery setup is to start off with 2 new batteries that are the same make and model and pre-charge them before putting them on a vehicle.

Most likely it will short out and try to burn your truck to the ground like it did mine. Stop. Run away and forget you ever heard of this brand.

Yes, the charger has the logic to stop charging once the battery is fully charged. This is a good plan, especially if you do not use the tool often as you will always have a charged-up battery when you do need to use the tool.

You can charge that if you can get it to work. I was not able to charge a single battery with mine. It keeps shutting off like it is overloading or something. Total junk. Buy something better. You get wht you pay for.

It will handle two batteries okay. whether it will charge both or only the one it is connected to depends entirely on how you batteries and electrical system are wired.

Yes, it does prevent over-charging. This is accomplished by the charger switching to a type of stand-by mode when the battery is fully charged. Its LED display shows the specific cycle in which the charger is operating. If the battery power drops to a level below full charge, the charger switches to charging mode to top-off the battery again. I am completely sold on this CTEK Charger! Also, it CAN re-charge a supposedly "Dead" battery, if the battery is still capable of accepting a charge. This is achieved through its "de-sulfation" (altho this is not the correct term) process.

Yes the unit will stop charging the battery when the charge cycle is completed.

No I don't believe so your battery should be wired in series which means one draws off the other one would do on your main battery
1990164
No. This is for a single input. If you want to run two generators to two batteries you won't need the isolators at all.
827820
yes I don't see why it would not work, you should use a charge controller to prevent overcharging
1897459
No. A battery isolater is technically different and includes electronics internally to isolate the batteries. This is nothing more than a switch and is actually PREFERRED over isolaters. You will also need proper battery cables to wire up a dual battery system.

Not sure, but this isolator has been charging my spare camper battery for 2 + years without issue....

No, it will remember. Mine actually knew what battery type I was charging once I hooked up the batteries (2 - 12v).
1014531
It ok to do either one , the battery it self has a limited number of charges. I keep mines charged haven't had any problems with it.
1205402
Yes as far I know you can. I have charged both batteries with it and have had no problems.

You may way want to buy a charge controller to keep the battery from overcharging.

Not exactly sure of the question but it will charge two trolling batteries at the same time. I would put the cranking batteriy on a two battery switch and charge it separately when and if it needs charging. You can separate your trolling batteries to avoid running down the cranking/starting battrty. Hope this helps.
