Tracker Lithiums

[Fast Eddie]

For some reason, my 8 month old (as far as I know) tracker lithiums either are not charging, or only charging a little. This is the 3rd time I have arrived at the boat with all lights on the charger green, and 4 hrs later the battery drain causes the ghost to shut down. The ghost won't turn on at all. When I return to the storage facility and plug the charger in it reads 10% on one and 20% on the other 2. The cranking battery remains full. Not sure if the batteries are bad.... the charger is bad.....or whats going on. This is an occasional problem. I do know that the facility has someone pulling enough to trip the ground fault. Not all the time but occasionally. Shouldn't the charger restart and continue charging when the ground fault is reset? Anyone else have a problem with the tracker batteries> I'm sure all the great minds out there could help.
Thanks

First I would make sure my charger is working correctly. I think your local boat dealer can do that.
Then, if the charger is good, I would take the batteries back to where I bought them, and have them checked out. You should get more that eight months out of a new battery.

A battery can show full charge with a meter and still be bad.

First charge the batteries to full charge
Your meter will tell you if they are taking a charge. Should read 12-13 volts disconnected from charger. If they are not taking a charge you might have a bad charger. Try a portable battery charger if the boat charger is not charging them
Next
Get a load tester from Napa auto. Best 75 you will spend
It’s not hard to use
It puts a fully charged battery under load for seconds and the results will tell you if the battery is good or not. A battery can show full charge with a meter and still be bad.

With the load tester you will be able to identify the bad battery rather than guessing

Is your charger set up to charge lithium batteries? If not this could be a problem as the charging cycle curve is different than for lead & agm’s.

Just like the reply above, make sure your charger is indicated for lithium batteries.

Thanks Guys. There is a big LI in the center of the charger. This morning all was green, so my partner and I fished the DMO WE fish for Him Tournament and by 12:30 the trolling motor shut off. When I got back and plugged the charger in it read 70% for the cranking battery, 10% on the first lithium and the other 2 read 30%. About 30 minutes later they were all green. Going to the dealer Tuesday and will let you know. So far they can take the ghost and lithium's and....Junk em. This is the second tournament this has happened. All practice (3 days a week) no problem.
