BATTERY STORAGE GUIDELINES:
1 Any time a battery will be stored unused for an extended period of time (over 30 days), certain precautions will
help assure that the battery will not be damaged and will be ready for use when needed.
2 Bring the battery to full charge before storing it.
3 If the battery is in a vehicle, it is often best to disconnect the negative battery cable.
4 Install and keep terminal protectors in place and keep the battery clean.
5 Store the battery in as cool of a location as possible.
6 Monitor the battery on a regular basis.
7 Bring the battery to full charge before it is stored. This is the best insurance against internal damage due to
remaining in a discharged state for a long period of time, and against freezing in extremely cold weather.
8 If possible disconnect the negative battery cable if the battery is in a vehicle (this is must to prevent battery
discharge as well fire accidents). This will prevent parasitic drains in the vehicle system from discharging the
battery at a faster rate. If the negative battery cable cannot be disconnected, more frequent monitoring and
charging will be needed.
9 To prevent accidental discharge, install terminal protectors on exposed terminals. Keep the battery free of dust,
dirt, moisture, and conductive materials like damp cardboard that could allow the battery to discharge slowly
through external paths.
10 Cool temperatures retard the internal reactions that cause self discharge and internal grid corrosion. Find the
coolest storage location that will not cause the battery to freeze. A battery that is kept at a 65% SOC or higher
will not freeze until the temperature is below -32°C (-25°F) A fully-charged battery will not freeze until the
temperature is below -54°C (-65°F).
11 Monitor the stored battery regularly by checking the built-in hydrometer or OCV.
