  • Never connect the positive and the negative of the battery with metal
  • Never ship or store the battery with metal
  • Never cut or puncture the battery
  • Do not expose the battery to water
  • Do not expose the battery to fire & high temperature

Storage &Non Use

  • Storage in a dry place with temperature of not exceeding 30°C
  • For long term storage keep battery charged 30%-50% of capacity
  • Do not storage battery with metal
  • Use terminal post covers to prevent any short circuit circumstance
