Warnings

  • Do not immerse the battery in water or sea water. Keep the battery in a cool dry place when not in use.
  • Do not use or leave the battery near a heat source (i.e. heater, furnace, fire).
  • Use the battery charger only as directed when recharging.
  • Do not reverse the positive and negative terminals on the battery connections.
  • Do not discard the battery in a fire, furnace, or other combustible space.
  • Do not connect the battery directly to an electrical outlet.
  • Do not short –circuit the battery by directly connecting the positive and negative terminals with metal objects.
  • Do not directly solder the battery or pierce the battery with a nail or other sharp objects.
  • If the battery gives off an odor, generates heat, becomes discolored or in any way appears abnormal during use, or while charging or discharging, immediately stop using it.
  • If the battery leaks and the battery contents (electrolyte) gets into an eye, do not rub the eye. Instead, flush the eye(s) with clean water and immediately seek medical attention or it may result in injury to the eye(s).
  • Do not use the battery in a location where static electricity or magnetic fields are great or it may result in damage to the battery safety devices.
  • Do not leave the battery in high temperatures (i.e. in direct sunlight or in a vehicle in extremely hot weather) or it may overheat, and its performance will be degraded, and service life decreased.
  • Tape the battery terminals prior to disposal to insulate them as discarded batteries may cause fire or explosion.
  • Follow manufacturers instructions.

*Power Draw calculated from dividing the battery amp hours (dependent by model) by estimated runtimes provided  from Aqua Vu® website: https://aquavu.com.

*Runtime estimates are based on manufacturer represented power usage with factory default settings. Changes in user settings like screen brightness may impact power draw and therefore runtimes. As MarCum is not affiliated with the other companies listed, please contact the individual manufacturer for any further information. MarCum calculates runtimes based on amperage of the battery divided by the power draw of the model number. MarCum will update power draw information as provided by manufacturer.
