Will this charger charge both a deep cycle and a cranking battery and can the cables be extended?
1335213
Yes it will charge both and you can extend the wires but you must use the same gauge and the same kind of wire.
1335214
yes, but the batteries must be the same type - traditional lead-acid, AGM, gel
1335215
Yes it can charge both types. As far as extending the cable, I don't know, but it would probably void your warranty.

I would not. You could easily overcharge the battery where as a regular charger has a regulator on it. This is to be used to charge another vehicle/motorcycle for a short time; until the other vehicle can be started.

Yes. This charger has 3 leads coming off of it and every battery will get it's own charging cable. I will have to recommend against buying this charger. I had mine for 2 years and 4 months when it went out and didn't terminate charge boiling 2 of the 3 batteries.

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.

If you place the batteries face up with the 3 contacts on your left and the slide them into the recessed slot, the charger will work just fine. I have used it for charging 3 different brands of batteries and had no trouble at all.

Don't know about the platinum batteries, but I have 2 deep cycles for a trolling motor and a starting battery for the outboard, and it handles all 3 just fine. I don't believe it makes any difference in charging time whether you charge a single battery, or all three together. So far, I've been very happy with this unit.

Yes, but it is designed to charge deep cycle batteries. I'm not sure on connecting it to other types (such as automotive batteries). As soon as the battery is charged (reaches a certain voltage) it will automatically go into a trickle charge mode where it provides minimal power to maintain the charge. This mode is designed to prevent overcharging. As an aside, I'm not sure why you'd want to buy this to charge batteries instead of buying a regular battery charger. This unit would be overkill for such applications, since it is designed to provide DC power for the cabin of an RV/Travel Trailer while simultaneously charging the house/cabin batteries.

Yes, this is a deep cycle battery. Also long-lasting at 35 amp-hours of charge. Should be great for an electric trolling motor.

Yes. This charger works 3 batteries. For my setup, I have for my boat a marine cranking battery. Then I have 2 full deep cycle batteries for a 24 volt trolling motor system. I used to charge them one at a time which was a major pain. Plus I never realized that with the primary cranking battery, running the battery off the alternator once running will not fully charge the battery. It will only get to about 70 percent full. However with this battery charger, it has an internal computer which will properly charge and maintain the battery. The other good thing about this charger is that if you only have 2 batteries, you can still use it. Just pair the other free connections to one of the batteries. I contacted ProMariner customer support directly and they confirmed this is possible and safe. Overall happy with the product!

No, not recommended. If the required load to maintain the two batteries (assuming they are wired in parallel) is unbalanced, this can damage the charger. These are cheap chargers, save yourself some grief and buy two.

I am not an auto-mechanic. I purchased this charger to charge a 12V Marine-grade battery. The battery was completely "dead" but was only a year old. There is a deep cycle-recondition selection. I chose that and it took a full 3 hrs to go through the cycle. It charged the battery, which is now going on 5 years old and STILL re-charging on only the standard charge. I hope that helps answer your question.

No, not advisable. If you DID attach a larger external battery, this device's charging and inverter hardware is not designed for a longer run-time. So, you run the risk of overheating the unit during longer re-charge or discharge cycles. Also, this UPS uses a SLA (sealed lead acid) battery. If you were considering a "car" or "marine" battery, which have different charge/discharge characteristics, the battery might be ruined (or explode) if used with this UPS.

I can't give any specific advice on this charger, however, I wii say that you would be better off with a different kind of charger. I purchased, the second charger, from Amazon and it is a "Battery Tender Jr." . It costs about double but you will make that difference back in extended battery life as well as in being certain that your battery will always be ready to start your generator. The one I recommend is left plugged in to your machine and it keeps your battery in top shape without the damage that occurs by leaving a normal trickle charger plugged all the time. The unit comes with a plug that you connect to your battery and has a quick disconnect that you should use when starting ang operating the machine. Watch the polarity. Good luck.

Sorry I really don't know if that would work. However I use a trickle charger for a car battery and use battery to power my trolling motor and the charge last about five hours of continuous use.

This Charger , in my opinion, is a great charger and I have three (3) of them. I have charged deep cycle batteries with good results. I guess you need to discuss your concersn with the people who say it does not work well for deep cycle batteries. Research is important prior to your final decision.

Depending on the setting, yes. It gives pulses to deliver the charge gradually over time and until fully charged pulses now and again as some sort of assistance to leveling the full charge. On deep cycle it pulses even harder, this is the correct way to charge deep cycle batteries. I am very happy with this charger. Alex

Yes, the deep cycle type. I use a 101 amp hour battery and get about 4 hours of run time pushing a 2500 lb. boat.
