Battery Over Discharge in Regulated Mod

[bhangra]

Hey Guys,

I recently purchased an SMY God Mod that uses 3 18650 batteries. I have been using it with 3 brand new Samsung 25r for a few weeks with no issues. I was going out of town last week and turned off the mod by clicking 5 times, and left the 3 batteries in the mod. When I came back, all the batteries were under 2V.

Is it common to have batteries discharge in a mod when its off for a week? I also have and IPV2 and this has never happened. Its annoying that I have lost 3 batteries, but I want to make sure it doesn't happen again.

Thanks for your help.

It's probably not a good idea to leave batteries in a mod you're not using daily. Mod must have been drawing power and not monitoring the batteries.

That kinda sucks. A regulated mod can draw power even when off?

I wonder how long it would take for the batteries to discharge if I left it on but never fired it. That would show if there is in fact an idle power draw.

Fist, let's get off calling everything a "mod". If it has electronics it's an APV. And yes - some of them don't actually power off, remaining in a perpetual standby mode that will continue to drain batteries. The classic example of this is a Provari. Whaaa....? A Provari does that? Yeah. You can put it in what is, in effect, a standby mode but you can't actually turn it off and stop it from drawing battery power.

If this only happened once that doesn't mean it ruined your batteries. But you do need to use a charger that is designed to recover under voltage batteries - that would be just about any Xtar charger. Multi-chargers that try to do everything - both Li-On and NiMh and NiCD - like the NiteCore i2 and i4 can't recover under voltage Li-On batteries.
