GROUNDING INSTRUCTIONS
Batteries and chargers: make sure your charger is compatible with your batteries, and set its charging algorithm to your battery pack before you use it.
The charger must be grounded. If it should malfunction or breakdown, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This appliance is equipped with a cord having equipment grounding conductor and grounding plug. The plug must be inserted into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances.

Personal Protective Equipment (PPE): It is recommended to wear proper personal protective equipment as required by the Chemical product label instructions used in conjunction with the appliance.
1.5 Battery Information
Batteries and chargers: make sure your charger is compatible with your batteries, and set its charging algorithm to your battery pack before you use it.
Keep Batteries at Room Temperature: That means storing between 32 and 80 degrees F (0ºC to 27ºC). The worst thing that can happen to a lithium-ion Battery is to have it exposed to elevated temperatures.
Batteries Lose Capacity Over Time: Batteries naturally deteriorate over time whether being used or not. Batteries deteriorate at a rate of 10% run time per year.
Fully Discharge vs. Partial Discharge and the Effect on Battery Cycles: Unlike lead acid batteries typically used in auto scrubber, the Kaivac Battery is not damaged by fully discharging. The BMS (Battery Management System) has a cutoff voltage of 30V which protects the Battery from experiencing full discharge. Running the Battery to full discharge will reduce the amount of charge cycles. The expected hours of use are approximately 600 hours. For example, if running to full discharge, you would expect 400 cycles. If you run to 80% discharge, then you would expect to get more cycles (500 cycles).
Extended Storage: It is recommended to discharge to 40% capacity (35V) and store in a cool location (between 32ºF to 80ºF or 0ºC to 27ºC). Hour
Battery Gauge: The Kaivac Batteries come with a built-in Battery Gauge or “Fuel Gauge” which shows the approximate run time remaining.
Disposal: Properly dispose of Battery at a local recycling location.
