I have 3 sets of these lights. I want to use them on my boat. Will they drain my cranking battery? Or should I get a second battery.

I have 2 sets on my pontoon and am adding 2 more I will definetly run a secon battery, but if you put a switch on them and use them for 2 or 3 hours, you could probably get by with one battery, hope this didn't muddy the issue to much . It's always nice to have a extra battery on board, in case your starter battery decides to belly up. Good luck and enjoy !

I installed an on/off switch w/a fuse to act as a circuit breaker in case of a short anytime so I can use them when I want & I've never had a problem with battery drainage.

I have two sets of these lights. I have had them for about six months and use them constantly. They work great. I've had no trouble with them. Either you got a bad set or there is a wiring problem. The odds of neither of them working is slim so I would recheck the wiring. I hope this helps.

Keep the extra batteries clean, dry and fully charged. Also, rotate the batteries for use. Why have three if you only use one. Not sure if not using them causes issues, but it can not hurt to rotate their use. Best of luck. Alan

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!

On a small 12V incandescent light, polarity is not critical (positive and negative) to make it light, what can become important in a marine environment is corrosion from electrolysis. A good practice is to disconnect the battery when laying up the boat for any length of time.

I would also recommend the relay kit, as it will help with power consumption. Its a cheap was to give you piece of mind that your lights will work correctly.

I had them installed on my boat last season. They're not the brightest lights, but you wont find anything similar at this price range. Buy them, you wont regret.

These lights all fit. You need to do the math on battery power vs volts. If not enough batteries the light will not work.

If you are referring to the main engine starting battery then yes. If will not maintain the other system batteries, they simply are not large enough to do that. You will need to keep a check on the water levels unless it is a sealed battery.

I use mine on my boat battery. Have not had any problems to date but the boat has not been used a lot so we are talking maybe 5 - 10 charges.

From what I've read online - the grips shut off if power runs low and they will flash and turn cold meaning you have to reset or cycle them off and back on - the condition is that the battery or alternator can't keep up on the high setting -- might be that the place they are wired in is not ample or that it just can't keep up and they fault -- so it won't run you down and leave you stranded -- my advice would be to run them on a lower setting and try to find the edge -- personally I put a switch on my headlight and just run my l.e.d. daytime lights when I can -- mine haven't done this yet but winters not here either!! hope this helps! singletrackjack on ADVrider!

They will run fine on those batteries. The lights consume very little power since they are LEDs. The time they will run will depend on the amount of batteries you choose to run in parallel.

I can't exactly answer the amp draw as it is so small it's almost immeasurable on the meters on my boat. Prior to installing the 4 underwater lights I can tell you that I had a 20 amp dc draw on the batteries when I had ALL the halogen lights on my boat turned on. That included 19 total lights in the cabin/salon area and the kitchen. Not only were all the lights extremely hot, they sucked a lot of juice. I replaced all 19 lights with new led lights and with those 19 along with the 7 cockpit lights and 3 led cup holders and 4 underwater lights the total draw is less than 2 amps. That was a huge difference!! The underwater lights on alone don't move the meter at all so, again it is negligible. I don't know what the lumens rating was, but I am extremely happy with the results on my boat.

I don't use the charger supplied with the light - it seems to be ineffective time wise. It also seems to have a hard time making/keeping electrical contact, which could actually be your problem. I use an external charger and also have several other rechargeable batteries charged up to use if needed. I know, it's a pain in the butt, but that is the reality. Other than that, they are a good headlight.

I do not know the answer to that. I use them on my pontoon boat and have only used them 3 times at night. They are a great little light. A pair of replacement bulbs would probably cost nearly what the lights do.

Are you using the heavy duty cells that came with the lights? I suggest alkaline batteries..I used the batteries it came with and had no problems. Alkaline lasts longer. They don't drain a lot. Turn lamps off when not shooting, that helps. I'll bet its your power source.Blaise

No real suggestion. I presume 12 volt car battery. Possible poor connection? Current should be less than 12 amps. Mine stays bright for hours (should get > 100 from deep cycle marine battery).
