Battery Charger question

[JRJ]

Looking at purchasing a 3 or 4 bank charger for my pontoon, anybody ever use these (NOCO Genius Chargers)? Price is good. Since I'm letting it charge for 18-24 before going back out, how many AMPS do I need?

[Kevmc]

Have no experience with NOCO...
Dual Pro is very good, comes std. on new Rangers....
Best for batteries is to get them charged soon after use, would NOT recommend low amp or trickle charge.
20 amp per bank would do you good.

I agree with Kevmc...no trickle chargers...12-15 amp/bank would be my minimum.

I'm running a Minn-Kota 220 (2banks/10amps per bank) and charge my 29series batteries in a matter of a few hours, after a full day of trolling motor use. I wouldn't use any charger with less than 10a/lead ... but, that's just me.
I believe my buddy, cjpar3, has a NOCO 3lead charger on his boat .... and so far hasn't had any problems. But, I don't know which one he has as far as amps per bank.

If you have room for it, a MK330D on Amazon is in the same price range as a NOCO Gen3 30a (10a/lead), and actually about $20 cheaper at around $230. I think the big draw towards NOCO is its small size/weight.

You might consider sending a PM to CatFan and see what he knows about it. He's our go-to battery guru IMHO.

After looing at the reviews, thinking of going with the MK330D. Found it on sale for $199. Thanks.

Noco is best charger out there for the money. Have replaced 3 DualPros with NOCO in last year. Every guy is more than impressed with their charge time verses the other. 10 amp is best.

So what I gather from reading the above post it is better to charge a marine deep cycle lead acid battery on a high amp charge than a low 2 amp charge. Is this correct? If so could someone please explain why. I have a brand new 32 ser 155 ahb and I want to get the longest run time out of my battery. Thanks in advance. Chip

The more time a battery sits at less than full charge, the more sulfates attack the plates.
Put on charge as soon as you can, charge back up quickly and leave on charger. Good chargers will monitor and keep full.

What kind of battery are you talking about. Is this a smaller battery? Never heard of a 32 series. On smaller batteries lead acid or gel cell such as mower or motorcycle battery they have smaller plates and are recommended to be charged at no more than 2 amps because they build up to much heat and will warp the plates. But on full size batteries the higher the amps the better for quicker charge. Your truck or car will be putting out in the neighborhood of 80 amps or more. The faster you get it back to full charge the longer the battery life.

I’m running a MK345D and MK230D. I have them wired together. Open the rear hatch, plug up one cord, and throw 15 amps at each of the 5 batteries. I rarely have to add water to any of the batteries and they are used almost daily.
