  • Caution in Use
    • Unplug the battery by holding the connector/plug and not by pulling its wire.
    • Do not expose to, dispose of the battery in fire.
    • Do not put the battery in a charger or equipment with wrong terminals connected.
    • Avoid shorting the battery terminals
    • Avoid excessive physical shock or vibration.
    • Do not disassemble or deform or incinerate the battery.
    • Do not wash or clean or immerse in water.
    • Keep out of the reach of children.
    • Battery must be charged in appropriate charger only.
    • Never use a modified or damaged charger.
    • Trickle charge (@0.1C) every 6 months to prolong battery life and while keeping battery for storage.
    • Do not leave battery in charger over 24 hours.
    • Store the battery in a cool, dry and well-ventilated area.
    • Avoid high humidity and corrosive gases environment while storing the battery.
    • Regulations vary for different countries. Dispose of in accordance with local regulations.
  • Product Warranty

  The period of warranty is twelve^# months from the date of shipment DynLithium guarantees to give a replacement in case of battery defects proven due to the manufacturing process instead of misuse or abuse at the customer end.

  • Note
    • You should also consult the following documents: Cell datasheet, Analyzer report and DC Load test-report.
    • Actual voltage and capacity in use will be affected by various factors, including temperature, discharge rate, charge rate and method (if applicable), end point voltage, history (e.g., past use, storage) etc.
    • These products contain devices and/or circuits to protect the pack in the event of control circuit failures e.g.

  charger failures. They must not be used as a main means of charge/discharge control. The protection circuits & devices have a response time of the order of a few milliseconds.

  # Warranty period depends upon charging and uses conditions. Please discuss and share technical details on charging as well uses, in order to conclude on the applicable warranty period.

  NOTES:

Batteries should be installed soon after they are delivered to avoid any issues with the insufficient charge at the time of installation.
