14250 battery question

[Sewknitty]

Hi MadVapes,

Got my order just before snow covered my street (again). Thanks for your usual speedy service!

These cutie pie batteries are so tiny the shortest spring tension on my Rapid Charger is too long and they're also too short to fit into my Tenergy charger.

I rigged something to hold them against the brass thingies to charge and think they have. I also got a MultiMeter with my order which I set it to DCV, put the red prong on what must be the positive end because it has three holes in it and the black prong on the flattest end. It shows 4.06 volts, which should mean they're charged, right?

Do these batteries need a spacer for use? If so, would a coin do? The mod isn't firing and I need to rule out the battery as the cause.

Thanks in advance!

I use dimes or pennies as a spacer. They're cheaper than a spacer

The charge on batteries can vary a bit but a 4 volt charge is good for a battery that will produce a 3.7 voltage for the longest time. Some batteries will charge to 4.2 and some to a little bit less.. But you are right on with what you are doing..
