eGo-T Batteries: eGo-T 650mah Battery
Solid tactile manual switch for more user control, Five Click off/on .
For charging These Batteries we suggest our eGo USB charging Cable. The eGo-T 650mah battery features both eGo threading and standard 510 threading.
Pros: small size
Cons: wire broke after 3 months
Final Thoughts: battery life is as expected, needs to charge often, if it didn't break after 3 months of regular use I'd think about replacing it.
