Sudden Battery Drop

[LewisW295]

Good Evening All,

I'm currently using 2 x Samsung 25R batteries (purchased same time and married) in my T-Priv. I was vaping away without charging them when I got a low battery warning. I plug it in via USB and there's a 10 - 15% difference in charge level between the two. This is currently at 6% after a few minutes charging. Any advice guys? The mod is regulated and whilst I have 2 sets of 25R batteries, they are never interchanged. I don't particularly want to replace the 2 cells as I'm saving spare cash for a 2nd dual battery mod. But I'm not going to compromise on my own safety. Bewarned, this is my first external battery mod so expect silly questions

Regards

I would recommend getting an external charger you can get a good one for about $20. With that being said when you drain batteries all the way down the voltage will not be equal, at the end of the charge the mod will balance the cells out. An external charger will properly charge each cell independently to 4.2 volts and it will do it faster without the cells getting too hot.

If the mod has balanced charging.

External charger for sure. If not do full charges. If you don't give them time to balance they will get further and further off each other. If you can do a full charge on one battery it might take a half hour for the other batt to balance out. Or even longer if it's that far off.

I don't usually use the USB charger. I have a Efest battery charger and I Rotate my cells into that usually.

It is not unusual since each battery has a slightly different capacity, internal resistance, etc., it results in the battery voltages differing as they discharge and the readings on the mod may be inaccurate to some degree. Best to check with a multi meter.

Thanks for the info. Unfortunately I don't own a multimeter to check.

Honestly, charging externally is the smartest thing to do.
Even on a DNA chipped mod, which has decent charge balancing, it just isn't a good idea, unless you like ruining batteries.

Fully agreed, I only use my USB when I'm in a pinch or want/need the pass through (usually gaming so I don't have to switch batteries), otherwise everything goes in my eFest SODA.

Out of curiosity, is it normal for spring loaded chargers, like the SODA, to scratch/slightly dimple the negative end of the battery?

If your sleds are rough or very tight, I would try stretching them a bit and possibly some lubrication. My nitecore intellecharger was pretty tight in the beginning, and until it saw some use, I had to be pretty careful. If the pressure of the spring is so tight that it's actually denting the bottom of your charger, I probably would replace it unless you are able to stretch/lubricate it enough to the point it stops doing that. It's not ideal when it happens, and if it's routinely stiff/putting too much pressure on the battery you will want to replace it with something else.

Well, to put it correctly *I* would want to replace it with something else. You can get battery chargers without springs and etc.
