Charger/ battery issues. Please help!

the AW IMR's are most used, but the efests are good batteries too, only thing I have noticed with the efest is size is slightly different.

also from what you said about your batteries at least 2 of them are not IMR. IMR's are safer chemistry batteries meaning if they do vent (ALL batteries can vent) they will not flame up li-ion protected

A protected battery is always the safest choice. A dead short will cause the PCM to quickly trip (like a fuse), for 18650s at ~6A. The amount a heat a 'safer chemistry' battery will generate with a dead short is amazing melting cases and wires.

Here's a AW IMR18650 posted by Old Soldier.

A simple protection circuit like found on most Li-Ions would have tripped long before this could happen.

...I checked my batt's voltage using a multimeter just now, and it shows no voltage; the "hand" does not move at all. .

If it's a protected battery you've probably tripped the low voltage cut-off that keeps the battery from draining below about ~2.7ish V. Put it in your new charger for a while, it always provides a very small amount of current and should reset it.

IMR batteries have a higher discharge rating than protected batteries, if your mod needs that higher discharge rate, you can´t use protected batteries, so safe chemistry batts are the best choice.

If not needed, then go with protected batteries. Either way, a shortstop is an inexpensive added protection.

I've been using these in my vamo without a problem and they seem to last a long time:
