User questions & answers

Question:	Does this charger come with qiuck disconnect plugs on the positive and negative terminals
Answer:	No, the charging cables are bolted directly to the battery terminals - you would have to modify your installation for quick disconnection
Question:	how long are the supplied battery wires for this unit
Answer:	Supplied with prewired 6' cables for 2 batteries. Factory extensions are available separately.
Question:	Mine did not come with a terminal that connects to a battery. Am I supposed to buy an adaptor for it
Answer:	I am in the process of returning the one i got. the model number was 43012m21, not just 43012. I contacted ProMariner and they told me that i was sent a custom model that had some female plugs on them without any adapters. I am a little annoyed because i paid more for this one than another link on amazon because this was in stock. I almost cut the cords and put on my own connectors but i felt that buying a new item i should not have to do this. you can buy the male adapters for the connectors but you would probably be paying about 15 to 20 dollars for making your own cables. amazon should be sending me the correct model currently but im hoping they dont just send me another custom model. hope this helps other people because it took some work to figure this one out.
Question:	This charger comes with Intense Curl Cream? Where are the charger spec's
Answer:	First of all What is Intense curl cream?

User questions & answers

Question:	I have two batteries hooked up in series for my trolling motor! Do i have to disconnect the battery s before i plug it in or can i leave it in series
Answer:	The batteries do not need to be disconnected as long as each charging bank is connected to your batteries in 6-volt or 12-volt increments.
Question:	Can i simply splice in a length of same gauge wire to extend the length of the cables
Answer:	yes
Question:	My application is a 36v golf cart (3 x 12v) - I'm assuming that I could use this for a battery maintainer (one "channel" for ea 12v battery
Answer:	Yes. Channel 1 to battery 1, channel 2 to battery 2, channel 3 to battery 3.
Question:	is it ok to use just 2 banks to charge two battery's when you have a 3 bank charger ? a gen 5x3 3- bank, will it hurt the charger
Answer:	The bank you don't use will not turn on because the unit will not detect a battery. You should be OK. I recently had mine connected to 2 batteries with no issues. Just added a third battery and all is well.

User questions & answers

Question:	Has anyone come up with creative mounting ideas for this panel? I am just bungee cording it over the cover now
Answer:	Shoe has good support and I can go 12,000 steps a day in them.
Question:	Does this panel get hot while charging a battery? Can I mount it on a boat cover with magnets
Answer:	Usa. 10
Question:	Can I also charge my single 12 v battery with this
Answer:	I have a feeling the "M" in DM might mean medium. I have a size 10 1/2 shoe, and I have always purchased just the standard size shoe and they have always worked. When I ordered mine it was size 10.5 M (no "D") and the fit was way too small! Almost as if it was a women's shoe. The material was literally "bulging" out everywhere. Read the comments & reviews and you will see others had the same issue. I was about to throw in the towel but decided to return them and try a different size 10.5 2E, and that shoe fits absolutely perfect and is one of *THE* most comfortable shoes I have ever owned in my life! Great value for the price, and the memory foam and "spongy" type sole make for a very pleasant walking experience. My recommendation is not order the M but try the E.
Question:	can you keep this pluged in while using 24v troll motor
Answer:	I am on my 5th or 6th pair, and have never seen any marks. I just tried and could not leave a mark.

User questions & answers

Question:	Can I charge two 12v batteries in a series with just one cable? I plan to use the other two cables for something else. Thank you for you your help
Answer:	Mine came with it.
Question:	If you need to extend the charging leads what size wire should you use
Answer:	I don't know if it'll work on a Toyota, I used it on a 1978 F150 and it worked well, good luck.
Question:	How long is the 115 volt power cable
Answer:	I don't know the answer to your question. If you can screw it to the pinion flange-the tool can be adjusted to the screw openings of the pinion flange, it should work, good luck.
Question:	Can this charge lithium ion
Answer:	This is not the exact one I purchased last year. The one I purchased was 100 pens. But this is not the same one I purchased. Not sure why amazon sent me the question.
