Another batt fix question, Can this one be fixed.

[poisonette]

Just found one batt fix on youtube for a shortie that had poor vape. And thanks to this forum, was told how to fix batts that don't fit carts correctly. Thanks everyone.

Ok, onto this next batt. It's a medium sized auto batt. When I got it, I put it on the charger long enough to verify it was fully charged (5 sec max) light on end blinked 3 times, light on charger stayed green.
Put it on multiple carts, nothing. No light at all. No light on a direct end draw either. (saw this trick for cleaning) Just got done trying the pin fix to see if it was the silicone thing like the shorites. Still nothing.
Is the batt concidered DOA or is there a fix?

If you have access to a multimeter you can check the battery voltage to find out if it's dead.

I have access to many multimeters. Where is pos & neg on these?

 

[JoeChemo]

Most multimeters autosense the polarity so touch one probe to the threaded area and the other probe to the battery's center conductor.

 

[poisonette]

I'll give that a try. What if it has a full charge like my chargers are sensing?

 

[JoeChemo]

Then I'd try different attys or cartos but sounds like you already did so. My guess is the battery will be dead or very low voltage. BTW, what model is your ecig?

If it's digital. If it's analog, you just bent the needle.

Further - the voltage will read zero. It's an auto battery. The switch won't be actuated until there is pressure or sound (depending upon the model).

Do they still make analog multimeters? I still have an old Triplett out in the garage.

Good point. Was assuming it was a manual batt.

 

[poisonette]

Yep, auto. But if you blow through the LED end, it activates it too. Just can see if it lights. lol

I'm pretty sure it's a KR808D-1. It's this one.

 

[Adrenalynn]

Analog meters are still the best for testing capacitors. Nothing like seeing the needle swing on charge to know if it's good or not.

I can't imagine how many sets of hands it'd take to hold the probes in there without shorting, blow through the LED end, and read the meter. Maybe precision clip probes, a value-hold meter, and a lot of patience. But yes, in theory that should give you a no-load measurement.

2 sets of hands helped but couldn't get a reading. Don't know if it was us or the batt cause we had trouble keeping a good connection. I mailed it back.
