Juiced Automatic Battery: TRY THIS

Well, I managed to do it. Twice I've been dumb enough to overfill my carts and get juice into a KR808D-1 automatic battery. Resetting it by blowing through both ends of the battery didn't get me any blinking LEDs, it wouldn't take a charge. Overall it was completely borked.

...and here's what I did to fix it.

You can get silica gel almost anywhere. It's in the little packets that come in everything from electronics to shoes. The packets that are conveniently marked "Dessicant: Do Not Eat" for those of us that think electronics and shoes might come with a snack.

Take the LED end of the battery and pop it off. Use a paper towel to blot up any excess juice you can see. Then fill the top with silica gel granules out of the packet, cover with a cart condom, turn it upside down--we're wanting both gravity and cohesion to pull the juice through the battery so it can all soak into the silica gel granules--and let it sit upright and upside down for a couple of hours. Then dump it out and repeat one or two more times until the granules start coming out dry. Dump out the last batch, put the LED cover back on, and you're done. Give it a reset by blowing through both ends and a full 8-hour charge.

well, here's a follow-up. It's not 100%. Worked fine on one battery, but the other one still has issues. Apparently there's still some juice stuck to the pressure switch, so it's bad about staying on after taking a hit unless you suck through the LED end of the battery. Which is a pain. Trying alternating blowing air into and sucking air through the LED end should free it up--and does for a while--but it doesn't stay working properly.

I'm tempted to just cut my losses on that particular one, invest in a tubing cutter, and harvest the connector to make myself a nifty little mod on down the road. Waste not, want not...

I had a new style kr808 batt that got too juiced and was lighting up whenever I held it connector side down.
All I did was let it sit standing upright on a paper towel for 3-4 hours and came back to find the paper towel had a little juice stain around the batt. Then I whipped it really hard a few times to get some more out and tried various things like twisting up a small piece of paper towel and fishing it around inside the hole in the middle of the connector end. I did get it back to normal operation and thats the closest I've come to killing one. Although my oldest batt needs a firm tap on a hard surface (LED side down) occasionally or it fails to fire. Had not thought about silica gel though... BRILLIANT!

What we really need is some kind of auto battery cleaning kit. Something made of a soft squeegee type material that can be stuck inside that hole and will expand once inside and can be fished around in there to absorb juice. Also something with a similar material on the tip that is firm and thin and can go inside the crevice between the threads and the center part and be rotated around to clear the air holes and restore airflow.

I fixed an auto accidentally.
I was wtching a you tube video on how to disassemble a carto.
I never did disassemble the carto but in the process of trying I moved the battery up a little bit from the battery housing. This was a battery I thought was dead ( still lit up in the charger though) but would not do anything when I took a drag off it.
Now the battery works better than new.
I take one drag and it just pushes the vapor into my mouth and does this for about 7 seconds.
Whatever the cut off time is. I love it.

I wonder if you dripped a couple drops of rubbing alcohol into the end with the pressure switch if it would get the juice out of the contacts so it would work....any thoughts on this...of course do the gel afterwards.

I think the most common probs with auto batts is too much juice gettign down in the center post, it doesn't necessarily short the battery but it gums up the trigger so it either doesn't fire at all or stays firing constantly. The trick is how to clean it without breaking it worse... pipe cleaners?

That's an excellent question...
Definitely try to drain the batts charge first I guess. Considering all the juice that gets in there anyway, how sensitive to a little alcohol could it be? All the same, I think you should try it first and let me know how it goes. hehe. ;-)

Good ideas on both. I know that I've had to clean out laptops with distilled water--fine as long as you don't apply power until it's fully dried. This may work for a sticky battery sensor too. I think I'll try alcohol or water on the dead battery that I still have--it'll take a charge, so the problem's a sticky switch. Since it's discharged at the moment anyhow, it's worth a shot.
