I'm buying new batteries. The charger is original to the boat 1993-18 foot. So I was looking at replacing the charger with a new one. I understand the new chargers are more efficient and monitor each battery. Duffy wants $650 for a new one, wow! Doers anyone have a better approach?
The charger in my 2017 Snug Harbor does not monitor individual batteries. I just did some quick price checks on reputable 48-volt chargers, and the price you mentioned does not seem all that unreasonable. Hopefully, theirs would come with some support if you needed it.
Let us know how things go, and thanks for posting.
Has anyone used a Zivan replacement charger?
I have been told that there are at least two(2) of my batteries that aren't holding a charge. How do I check to see which ones those are and what batteries are suggested to purchase?
@roclark You can get a specific gravity gauge from any auto supply store. By testing the acid in each cell, it will give you a quick overall view of that battery.
The problem you’ll face is that if you find only a couple or even a few weak batteries, but the rest are good, it’s not recommended to replace the weak batteries with new ones, since the batteries will then be “unbalanced”. It’s difficult to find replacements that are the same brand and like age of what you already have, so unfortunately, you may very well have to replace all of the batteries if some of them are weak or dead.
Trojan T-105 batteries are the standard, but any brand of a GC2 battery is fine. Again, the batteries should be matched brand and type.
@robhouston Thank you so much! That's great to know. Duffy replaced some of the connectors so it seems to be running fine now.
@roclark Terrific——it sounds like you came out of that one in great shape. Replacing batteries is not fun nor is it cheap.
Have fun with the Duffy!
