Forklift Battery - Exide Gel

Supplier: Exide Technologies playlist_addCompare

An Exide Gel cell has its electrolyte fixed in a gel silicate and is fitted with a valve which prevents any release of the charging gases.

Price Guide (Inc GST): POA

Exide Gel plates are manufactured with a lead/calcium alloy. The calcium in the Exide Gel cell replaces the antimony in the Classic cell.

This process contains gassing and eliminates water loss, provided that the charge voltage is correctly monitored. However the trade off with this type of product is a shorter cycle life than Classic cells.

The addition of the calcium as opposed to antimony allows for longer storage times with little open circuit losses (self discharge). Comparison of Exide Gel and Exide Classic. In Classic flooded lead acid cells the electrolyte is a free liquid which is set to a level just covering the separators.

This has the disadvantage that the cells have to be vented to release the gases which are generated during charge. The gases being hydrogen at the negative plate and oxygen at the positive plate.

Whilst on charge these gases may carry a fine mist of acid from the cell. This mist can be highly corrosive.

Classic cells are manufactured with a lead/antimony alloy. Antimony provides tensile strength to the lead for castability of the plates. Antimony also effects the electro chemistry of the cell on charge causing the cell to produce more gas and increase water loss.

The antimony alloy will increase the self discharge of the cell. Reducing Antimony can eliminate water loss and drastically reduce self discharge.

Sealed Cells filled with Gel silicate electrolyte, means:

  • No danger of spillage
  • Exempt from hazardous goods regulations
  • No chance of cross contamination
  • No Maintenance costs for topping up batteries
  • No special training required
  • No Health & safety Issues for operators

Minimising gassing, means:

  • No special charging area required
  • Can be sited in sensitive areas, i.e. food manufacturing

Bolted connectors, means:

  • No hot work permits required for repairs

Suited to opportunity recharge:

  • Giving high availability in low usage applications
