Lithium battery issue.

I was setting up all my electronics units yesterday and programming new gear. I had my radio on which is wired off my electronics fuse block. All of a sudden it just quit.
I plugged up my chargers for a bit.

When I checked them later, the electronics battery was still not running the radio and my charger was showing a red light. I figured the battery had gone to sleep after being drawn to zero so I got my jump box and threw a short charge on it.

I plugged up my charger again and the lights went green, yellow, red.

Today I hooked up a spare lithium charger to it, same thing— red light after green then yellow. I hooked up my jump box again and it showed 13.4 volts???? According to my charger, the battery is bad.Less than 3 years old. I put in a call to the company. Fingers crossed.

Fingers crossed for you. Hopefully they will replace it for you.

did the battery ever sit around any extended time uncharged? i lost one after letting it sit the winter months without recharging after last use in the fall (November) then when i went to charge in February it would charge but the light never turned green.

Keep us posted. Hope it works out well for you

It was taken out of my previous boat in October fully charged. I has worked fine while on the water and while we programmed everything. It just quit suddenly.

What little I know of lithium is that when they have no more power to give they just quit abruptly. Little slowdown or indication that it had a problem. Hope they stand up and do you right.

No reply from the battery company. I went to another sponsor yesterday and picked up another 12v100a lithium (different brand). I put the battery in question on a 15 amp wet cell charger and let er rip. I thought if it blows up, so what!

After about 2 hours, I unhooked the wet cell charger and hooked my spare lithium charger to it over night. This morning the Bluetooth read-out shows 13.8 volts and 100% charged. The green light on the charger indicates full charge.

I’m assuming the battery had gone to sleep or something and the drastic measure charge woke it up. This is new to me but maybe it can help somebody with a similar situation.

I’m still puzzled why my lithium charger wouldn’t pull it out of the funk. Every time I plugged it up, it would go green light, yellow light, then red light and stay red for hours. Red indicates the battery is less than 80% charge. Yellow is above 80%. Green is full charge.

You can bet I’ll have a spare in the boat from now on. I’m hearing more stories about lithiums going bad and the companies not standing behind them after they sold the battery with a 10 year guarantee. This battery was guaranteed 3000 charge cycles. I’m a long way from that!

My experience with lithium comes from having 4 of them on my sailboat and 3 on my PT18. When a lithium drops below it's minimum charge level and "shuts off"
the BMS goes to sleep and has to be woken back up. To do this you must completely disconnect the battery from everything for about an hour, then put it back on
the charger. Found this out after losing power to the dock and my sailboat batteries went flatline. Disconnected fot the recommended hour and they charged right
back up and have been fine for the last 2 years.

My Noco Genius charger will wake up the BMS if the battery ever gets that low, some chargers will do this and some won`t. Just hooking up a 12 volt source will usually trigger the BMS back on. Shutting down the BMS is a safety feature if the voltage gets too low.

I have a Noco Genius 10x2 charger on my cranking and Raptors/crappie brakes lithiums. If I have to replace my lithium electronics charger, it will be with Noco Genius. Very compact but great features.

Watching this for future info. Hope you get it fixed up MR Dux.

We use jumper cables to wake the dead battery up quite often! We carry a couple spares as well. Usually when it dies we can hook jumpers to a good battery and the negative to the bad battery and spark the positive and it will wake it back up into taking a charge! They’re a fickle animal these lithium batteries but last longer than anything else we’ve used!
