How to Fit, Charge and Carry an 18350
- Check the wrap before every use: never use a cell with a torn wrap or a dent.
- Fit it following your device’s markings, positive end to the positive terminal.
- Charge it in an external charger that takes 18350 cells.
- Carry spares in a case, never loose in a pocket.
How Long Does a Charge Last?
700mAh is small, so an 18350 suits short sessions at low power. Over months of use every Li-ion cell loses capacity; replace it if it gets hot, drains noticeably faster, or its wrap is damaged.
18350 Troubleshooting
| Problem | Likely cause and fix |
|---|---|
| Device shows low battery quickly | 700mAh doesn’t last long at higher wattage. Lower the power, or carry a spare. |
| Cell gets hot | You’re probably drawing more than 7A. Lower the wattage. |
| Torn wrap | Stop using it and rewrap or replace it. |
| Won’t fit | Check your device takes 18350, not 18650 or 18500. |
Battery Safety
Keep cells in a case, charge them on a hard surface and never unattended, and stay within the continuous rating. If you’re unsure whether a cell suits your device, bring both in and we’ll check.
