How to Choose the Right Custom Battery

  1. Voltage & Connector: Verify nominal voltage and matching plug or tail-cap interface for your model

  2. Capacity (mAh): Match cell capacity to your device’s drain—higher mAh for continuous use, moderate for intermittent operation

  3. Protection Circuitry: Choose protected cells with built-in safeguards against over-charge, over-discharge and short circuits when safety is critical

  4. Form Factor & Fit: Ensure correct dimensions and housing shape to slot seamlessly into proprietary battery compartments

  5. Charging Method: Decide between USB-integrated recharge options for field use or traditional smart chargers for home-base balancing

  6. Brand Reputation: Opt for reputable manufacturers who adhere to strict quality control and performance testing

Care & Maintenance Tips

  • Charge using manufacturer-approved methods and avoid over-discharging below recommended voltages

  • Store cells in a cool, dry place away from metal contacts to prevent accidental short-circuits

  • Inspect for any signs of swelling, corrosion or damage before each use

  • Rotate your battery stock periodically and retire cells that show significant capacity loss

  • Keep contacts clean by wiping terminals with a dry cloth before insertion
