BATTERY TYPES

Use only deep-cycle batteries with your Freedom Inverter/Charger. These fall into three broad categories: wet cell, gel cell and Advanced AGM (Absorbed Glass Mat) batteries.

Wet Cell Batteries

True deep-cycle wet cell batteries are characterized by relatively thick internal plates that are alloyed with antimony.

Common 12 volt marine/RV deep-cycle batteries are acceptable. Golf cart batteries perform well and may have a longer life. These 6 volt batteries must be

used in series connected in pairs. High

quality deep-cycle batteries offer good

performance and are available in a wide variety of sizes.

Wet cell batteries will give off gas as a natural result of charging and will experience some water loss. It is very important that the electrolyte level be checked frequently and topped off with distilled water when necessary. Follow the battery manufacturer’s recommendations for maintenance.

Never allow the top of the battery plates to be exposed to air, as contamination of the cell will result. Keep the top of batteries clean.

Always provide adequate ventilation for the battery storage compartment.

Do not use ordinary car batteries or engine starting batteries with your inverter/ charger. Beware of any battery that is rated in Cold Cranking Amps (CCA). This is a rating which applies only to engine starting batteries. In general, most wet cell batteries that are described as hybrid type batteries, suitable for either engine starting or deep-cycle applications, are a compromise and will have limited life if deeply discharged.
