High performance batteries that aren't hype
If you buy cheap batteries...that's exactly what you'll get
WORKS WITH: Prometheus Alpha Lights (and other 18650 lights)
What you get for your money
- Reliability: Less chance the cell stops working for no apparent reason (it happens)
- Consistency: Every battery has similar performance (as opposed to variable)
- Safety: Mechanical and electronic safety features (a "protected" cell)
- Lifetime: Longer total life span because of the characteristics above
Please note: most sellers rate this cell at 3500mAh but in real life they are 3400mAh...and that's how we label them. No hype remember? ;)
PROTECTION CIRCUIT: These batteries contain a specialized electronic "protection circuit" for user safety. The prevents over charge, over discharge, over voltage, and under voltage conditions.
RECHARGE EARLY AND OFTEN! Do not run these batteries until they are completely empty (when the light shuts off on its own). Doing so will trip the protection circuit and render the battery inoperable. The Foursevens Flex Charger and Xtar VC2/VC4 chargers are normally able to reactivate a tripped battery; however, this is not best practice and fully draining the battery causes long term damage to the cell.
PLEASE NOTE: Exceeding the maximum voltage of your flashlight can cause permanent damage to the flashlight. Before using these batteries please ensure that your flashlight is rated for up to 4.2V.
This battery is rated to 4.35V and 2500mAh, but most chargers only charge to 4.2V and that's why we have rated the battery at 2200mAH.
