Will this charger work on a marine battery that is rated at 14.4V peak? It looks like a car battery but apparently is a higher voltage?

It's a nominal 12V battery. Charging voltage is higher than 12V, but typically less than 14V. The 14.4V peak for your battery must be max charge voltage. I think your Yuasa charger work OK with your marine battery if it's an electrolyte battery, but I would use it only to maintain a charge on the fully charged marine battery because of the low charger amp output. I wouldn't use the charger with a gel or AGM battery without checking with a battery rep. The following is from the web: Bulk Charge Voltage The Bulk Charge Voltage of typical liquid electrolyte batteries should be about 14.4 VDC; AGM batteries about 14.2 VDC; gel cell batteries about 14.1 VDC. There is no one correct voltage for all types of batteries. Incorrect voltages will limit battery performance and useful life. Check your battery maker's recommendations. Float Voltage The Float Voltage settings should hold the batteries at a level high enough to maintain a full charge, but not so high as to cause excessive "gassing" which will "boil off" electrolyte. For a 12 volt liquid electrolyte battery at rest, a voltage of 13.2 -13.4 is normally appropriate; gel cells are typically maintained between 12.9 and 13.1. If the batteries are being used while in the float stage, slightly higher settings may be required.

It may not get the battery to a peak of 14.4V, but it will get it to a close to full charge condition. However, remember this thing charges at about 1 Amp. For a Marine Battery, it will take a long time if it is discharged. It will work fine if you are only trying to keep it at full charge.

Yes. I use mine to keep a deep cycle 12V marine battery charged. 12 volts is just a nominal term for the average target output of a battery used in a 12V system. When fully charged, all batteries exceed their rated voltage.

My charger, a ThruNite MCCC-4, outputs a charging level of 4.2v. When the battery reaches this level, shown on LCD panel, it shuts off, fully charged. The battery "likes" to hold an operating voltage of 3.5, so using a charging voltage of 3.8 would be conservative, and certainly safe. These batteries are very robust, and will not take more than they're designed for.

this charger will charge each battery up to 20 amps per bank,as needed.the charger monitors the level of the charge,and maintains the battery at full capacity.I installed this model on a 28ft bayliner,and left it on thru the brutally cold winter,all three batteries are still at 100%

I'm sure it will charge any battery that it's hooked up to. This unit charges my battery backup system. It's 5 deep cycle marine batteries hooked in series.

You can charge a marine battery if you take it out of the boat and charge on shore. DO NOT charge a battery in a boat with anything but a marine rated battery charger. Anything from VERY rapid corrosion of your outdrive to your boat exploding could result. People that don't understand marine technical issues shouldn't attempt to answer questions like this.

I'm not sure about this ? but I believe it will work O K . I have used this charger on auto batteries, on marine deep cycle and various types of the smaller sealed batteries such as those used in the small electric cars that children ride in for hours at a time.

Sorry, I don't know the answer. My boat has a dual battery 12 volt system. I routinely use the batteries (and run the engine) with the charger running.

It's only rated at 3 volts, so not very high.I tried a 4.2 volt LiPo as V+ and it fried it.

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.

I bought my from Harbor Freight for $14.99 and it is a very cheap p.o.c. but mine works. I charged 2 D cells with a mAh of 10,000 to mostly full in about 6 hours. They were dead when I started. This charger has a setting for 1.2 volts. My D cells can be charged past that so this might be the best that this charger can do.

I'm not a battery or marine expert, but I really don't see an issue. This is a great little battery, and the only issue I've been told is to keep it charged above 8v. I used mine on a custom 1975 Honda CB200. This little battery cranks it.

Would work with a marine battery with cigarette lighter adapter. Harbor freight probably has a float charger to keep it fully charged.

unless you change the crimp on ends this battery charger it will only fit marine batteries and side post batteries, not top mount post.

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!

7.2 volt to 18 volt is on this charger as mentioned in another answer. I bought it and use it for my skil 14.4 volt drill. the old charger slipped over the top stem part of the battery.

I use a West Marine 15amp portable charger:120vAC, 60hz, 15amp max (2-10-15amp settings) and I use 2amp setting so sounds like you're all set!

Honestly I don't know. I don't do much boating, but if the connectors are similar to that of a car battery then there's nothing stopping it from working. One thing I do know is that if it's a sealed lead acid battery do NOT charge it when the voltage gets near 11vt. It'll ruin the battery. As far as the equipment is concerned, I must admit there was something wrong with the packing and they sent me the wrong stuff. I bought a different charge controller called the 'cyclopse' and it worked fine.
