Flooded Lead Acid Battery Storage
Trojan: Periods of inactivity can be extremely harmful to lead acid batteries. When placing a battery into storage, follow the recommendations below to insure that the battery remains healthy and ready for use.
NOTE: Storing, charging or operating batteries on concrete is perfectly OK. The most important things to avoid:
Freezing. Avoid locations where freezing temperature is expected. Keeping battery at a high state of charge will also prevent freezing. Freezing results in irreparable damage to battery's plates and container. [Freezing can happen between -19 F (40% charge) and -98 F (fully charged)]
Heat. Avoid direct exposure to heat sources, such as radiators or space heaters. Temperatures above 80? F accelerate the battery's self-discharge characteristics.
Step by step storage procedure: 1. Completely charge the battery before storing. 2. Store the battery in a cool, dry location, protected from the elements. 3. During storage, monitor the specific gravity (flooded) or voltage. Batteries in storage should be given a boost charge when they show a 70% charge or less. Completely charge the battery before re-activating.
For optimum performance, equalize the batteries (flooded) before putting them back into service. Refer to the Equalizing section for this procedure.
Continental Battery Storage:
Q: Will a battery rapidly self discharge if placed on concrete?
A: No, placing a battery on concrete will not cause it to discharge any faster than any other surface.
Q: Can I store a battery indefinitely?
A: No, a battery will self-discharge slowly over time. Allowing a battery to sit in a discharged state will ultimately lead to severe positive grid corrosion and battery failure. An unused battery should never be allowed to sit over 6 months without a recharge.
