screw driver battery

[karmyn]

I have a screw driver - one of the originals ones from caveman. Don't laugh.
I have been using spider fire protected batteries 3.7V 880 mAh and they don't last for about an hour. I used my battery meter to see if they are good and the meter registers good. I'm using 901 attys.
Should I get a stronger /better battery? I don't know how big I can go with a screwdriver.

Probably just a *new* 16340 battery. They do wear out over time. When worn out they might still show the correct voltage when tested, but lose their charge rapidly and perform badly under load. I don't think you can fit a larger battery in the Screwdriver. If you are using low resistance atomisers then the AW IMR 16340 batteries might be worth investing in because of their better performance under high load. You can get them here, for example - 16340 | CR123 Batteries - Avid Vaper
