Typical 16340 / 700 mAh Battery Specs
| Parameter | Typical Value / Range | Notes / Comments |
|---|---|---|
| Nominal Voltage | ~ 3.7 V | Most 16340 cells are rated at 3.6 – 3.7 V nominal. |
| Fully Charged Voltage | 4.20 V ± 0.05 V | Standard for Li-ion (CC/CV charging) |
| Cutoff / Minimum Safe Voltage | ~ 2.7 V to 2.75 V | Many protected cells will cut off around this level to avoid damage. |
| Capacity | 700 mAh (typical) | This is your stated rating. Some cells claim higher, but 700 mAh is common. |
| Energy | ≈ 2.59 Wh | 3.7 V × 0.700 Ah = 2.59 Wh. |
| Max / Pulse Discharge Current | ~ 2 A (pulse) | Many cells in this capacity range are limited in discharge current. |
| Standard Charging Current | ~ 0.2C to 0.3C (≈ 140 mA) | For safe, long-life charging. |
| Max Charging Current | Up to 700 mA (some spec) | But pushing max charge current stresses the cell and shortens life. |
| Dimensions (Unprotected / Standard) | Diameter: ~ 16.0 – 16.5 mm Length (height): ~ 34.0 mm |
“16340” denotes ~16 mm diameter, ~34 mm length. |
| Dimensions (Protected versions) | Diameter: ~ 16.5 – 17.0 mm Length: 35 – 36 mm (sometimes) |
The protection circuit and tube sleeves add a bit of size. |
| Weight | 22 g | With protection circuit and sleeve |
| Cycle Life | 300 – 500 cycles (or more) | With good charging practices. |
| Operating Temperature Range | Varies, often –20 °C to ~60 °C or more |
**NOTE: IT IS HIGHLY RECOMMENDED TO COMPLETELY CHARGE ALL KILL LIGHT BATTERIES AT LEAST ONCE EVERY 6 MONTHS. AS WITH ALL LITHIUM BATTERIES, NEVER LEAVE BATTERIES UNATTENDED WHILE CHARGING OR IN THE CHARGER BASE WHEN NOT IN USE.
WARNING: This kit contains lithium ion rechargeable batteries. All lithium batteries are a fire hazard and should not be left unattended while charging. Lithium batteries should be stored in a cool, dry place out of reach of children and in a manner that avoids battery to battery or battery to metal contact. It is best to store lithium ion batteries fully charged to prolong the life of the battery.
