Q. What are the most common types of batteries?

A. The following are the most common types of batteries available. Refer to battery manufacturers websites for up to date information and product offerings:

• Lead-acid batteries
  
  • Requires maintenance.
  • Liquid electrolyte that needs to be periodically checked and filled with distilled water as needed. Has to be mounted upright (will leak through caps if mounted in any other position).
  • Considered hazardous material.
• AGM absorbed glass-mat batteries
  
  • Maintenance free.
  • Sealed battery with electrolyte absorbed in fiberglass separators consisting of a sponge-like mass of matted glass fibers. Operates under pressure to force the hydrogen and oxygen gases produced during charging to recombine into water, eliminating the need to periodically add water to the battery.
  • Spill-proof, leak-proof, and can be mounted in any position. Shipped via regular freight carriers.
• Gel-cell batteries
  
  • Maintenance free.
  • Sealed battery with a gelled electrolyte. Operates under pressure to force the hydrogen and oxygen gases produced during charging to recombine into water, eliminating the need to periodically add water to the battery.
  • Spill-proof, leak-proof, and can be mounted in any position. Shipped via regular freight carriers.

Q. What are the different sizes of batteries?

A. Different battery sizes available are:

• Group 24 10.5L x 7.0W x 9.0H approx. 70-85 A/H (20 Hr rating)
• Group 27 12.0L x 7.0W x 9.0H approx. 85-105 A/H (20 Hr rating)
• Group 31 13.0L x 7.0W x 9.0H approx. 95-125 A/H (20 Hr rating)
• Group 4D 21.0L x 9.0W x 10.0H approx. 180-215 A/H (20 Hr rating)
• Group 8D 21.0L x 11.0W x 10.0H approx. 225-255 A/H (20 Hr rating)

(Group size is determined by dimensions and amp hour capacity.)

Q. What are some of the most common battery manufacturers?

A. Here is a list of some of the most common battery manufacturers:

• Crown Batteries
• EastPenn-Deka Batteries
• Exide Batteries
• Discover Batteries
• Interstate
• US Batteries
• Optima Batteries
• Trojan Batteries
• Odyssey Batteries

Q. What types of batteries can be charged by ProMariner and On Board Solutions chargers?

A. AGM, Lead acid, and G.E.L. batteries can be charged. The chargers are factory set for lead-acid batteries. The settings depend on the type of charger, different models may have different settings, but most of our chargers have a lead-acid and a gel-cell setting. AGM batteries will charge at the lead-acid setting (NOT the gel setting). Some chargers carry 3 types of battery type profiles.
