Battery Safety Guidelines

At SHENTEC, safety is our top priority. Our batteries are engineered with advanced protection systems, but proper handling is essential to prevent accidents. Please read and follow these safety protocols for all Li-ion and Ni-MH batteries.

Operation Safety

  • Correct Fit: Only use batteries that are specifically designed for your tool or device model. Forcing a battery into an incompatible device can cause short circuits.
  • Avoid Extreme Temperatures: Do not use or charge batteries in temperatures above 140°F (60°C) or below 32°F (0°C). Keep batteries away from direct sunlight, ovens, or fire.
  • Moisture Protection: Never expose batteries to rain, water, or any liquids. If a battery gets wet, do not attempt to use it.

Charging Safety

  • Supervised Charging: We recommend charging batteries in a clear area and avoiding charging on flammable surfaces (like carpets or beds).
  • Damaged Chargers: Never use a charger with a frayed cord, cracked casing, or one that has been dropped.
  • Heat Dissipation: Ensure the charger and battery are in a well-ventilated area during the charging process.

Warning Signs (Stop Use Immediately)

If you notice any of the following, disconnect the battery (if safe to do so) and move it to a non-flammable outdoor area:

  • Strange Odors: Any "chemical" or "burnt" smell.
  • Physical Changes: Swelling, bulging, leaking, or cracks in the casing.
  • Excessive Heat: The battery feels unusually hot to the touch (not just warm).
  • Discoloration: Any signs of charring or plastic melting.

Handling & Storage

  • Terminal Protection: Do not carry batteries in pockets or toolbags with metal objects (keys, coins, nails). Metal touching the terminals can cause a short circuit and fire.
  • No Disassembly: Never attempt to open, crush, or puncture a battery. SHENTEC batteries contain sophisticated circuitry that can be dangerous if tampered with.
  • Drop Protection: If a battery suffers a hard impact (dropped on concrete), inspect it carefully for internal damage before attempting to charge it.

Proper Disposal & Recycling

  • Do Not Toss in Trash: Batteries contain recyclable materials and should not be disposed of in regular household waste.
  • Recycle Locally: Please take your old batteries to a local e-waste recycling center or a battery collection point (e.g., Best Buy, Home Depot, or local municipal recycling centers).
