Safe Storage of Batteries

Safe Storage of Batteries

Storage recommendations will vary depending on the battery technology;

VRLA AGM BATTERIES

(Applies to Regal Electro’s Valen, Topin, AGM, X-CEL and ENDUROX-CEL models)

AGM (Absorbent Glass Matting) batteries are of the VRLA (Valve Regulated Lead Acid) family so they are Maintenance free and nonhazardous. They are also sometimes referred to as ‘Sealed Lead Acid’ batteries.

Storage of these batteries has no special ventilation or handling requirements and the electrolyte in the battery is immobilized in the AGM, These batteries are considered as ‘dry batteries’ for shipping or airfreighting and can be handled and shipped accordingly. Although VRLA batteries are very easy to handle and store, damage to the plastic casing can result in electrolyte leakage and contact with lead so precautions must be taken.

STORAGE

  • Do not store batteries outside, exposed to the elements. Store indoors in a cool, dry location.
  • Do not store batteries in temperatures over 30ºC. The recommended storage temperature is 20ºC or less.
  • Do not stack pallets or allow any other material to be stored on top of the pallets or batteries could be damaged.
  • Do not store where the possibility of metallic objects falling on the battery may occur.
  • Do not store batteries directly on a concrete floor. Store batteries on a thermal insulation material such as pine flooring board or similar.
  • When removing batteries from storage use the oldest ones first. This could save you recharging

SHORT TERM STORAGE

If the batteries are to be stored for 6 months or less at 20ºC, before being put into service, nothing need be done at this time. If the batteries are to be stored for longer than 6 months, at temperatures greater than 20ºC, or installation is delayed beyond expected time, a refresher charge may be required.

A refresher charge is an equalization charge applied to a battery that is stored in open circuit (not float charging) condition.

If the storage temperature is 20ºC or less, AGM batteries must be charged at least every 6 months while in storage. For every 8ºC increase above 20ºC, the storage time between charges is cut in half. Therefore at 28ºC the maximum storage time is 3 months. At 25ºC the maximum storage time would be 4 to 5 months. Storage of batteries beyond the recommended temperatures or storage time, without charging, can result in loss of capacity, cell shorting and loss of float life. It can also void the battery's warranty.

It is always recommended to keep careful records of battery storage time and handling.

STORAGE AFTER USE

If the AGM batteries are placed back into storage after use, the above storage recommendations apply. In addition, it is also recommended to;

  • Remove anything that is connected to the battery for example flexible battery cables
  • Ensure the terminals are covered to prevent short circuits
  • Make sure battery is fully charged before going into storage
  • Ensure the battery has a date recorded of when it was last charged and the required date of recharge

VRLA GEL BATTERIES

 (Applies to Regal Electro’s Valen Gel and ENDUROGEL models)

Gel Batteries also fall under the VRLA (Valve Regulated Lead Acid) family so they are Maintenance free and nonhazardous. In some cases, VRLA battery technology is referred to as ‘Sealed Lead Acid’

VRLA batteries do not require any special ventilation or handling. The electrolyte in the battery is in the form of a thixotropic gel, and like AGM batteries, these batteries are considered dry batteries and can be handled and shipped accordingly.

STORAGE

  • Do not store batteries outside, exposed to the elements. Store indoors in a cool, dry location.
  • Do not store batteries in temperatures over 30ºC.
  • The recommended storage temperature is 20ºC or less.
  • Do not stack pallets or allow any other material to be stored on top of the pallets or possible battery damage may occur.
  • Do not store where there is a possibility of metallic objects falling on the battery. A metal object falling on open terminals could create a severe short and the plastic casing may be compromised.
  • Do not store batteries directly on a concrete floor. Store batteries on a thermal insulation material such as pine flooring board or similar.
  • When removing batteries from storage use the oldest ones first. This could save you recharging

SHORT TERM STORAGE

If the batteries are to be stored for 9 months or less at 20ºC, before being put into service, nothing need be done at this time. If the batteries are to be stored for longer than 9months, at temperatures greater than 20ºC, or installation is delayed beyond expected time, a storage charge may be required. A refresher charge is an equalization charge applied to a battery that is stored in open circuit (not float charging) condition.

If the storage temperature is 20ºC or less, GEL batteries must be charged at least every 9 months while in storage. For every 8ºC increase above 20ºC, the storage time between charges is cut in half. Therefore at 28ºC the maximum storage time is 4.5 months. At 25ºC the maximum storage time would be 5 to 6 months. Storage of batteries beyond the recommended temperatures or storage time, without charging, can result in loss of capacity, cell shorting and loss of performance. It can also void the battery's warranty.

Keep careful records of battery storage time and handling.

STORAGE AFTER USE

If the Gel batteries are placed back into storage after use, the above storage recommendations apply. In addition, it is also recommended to;

  • Remove anything that is connected to the battery for example flexible battery cables
  • Ensure the terminals are covered to prevent short circuits
  • Make sure battery is fully charged before going into storage
  • Ensure the battery has a date recorded of when it was last charged and the required date of recharge
