The EverExceed deep cycle MAX range battery construction is as shown in the diagram below. The positive and negative grids are cast from a high tin lead alloy to reduce grid growth and corrosion. The active material is manufactured from high purity lead (99.9999%) to minimize the negative effects of impurities.

The EverExceed deep cycle MAX range battery separator adopted is top quality mat of random woven acid resistant glass fiber, which acts as sponge-soaking up and immobilizing the electrolyte whilst maintaining good acid to plate contact and availability during discharge. “U wrapping” is employed to eliminate the risk of short circuits due to mossing and debris at the bottom of the cell.

The purpose of the separator is to maintain a constant distance between the positive and negative plates, thus removing the possibility of short circuits whilst allowing the active material to fully react with the electrolyte. The random weaving also results in an open structure, which offers minimal resistance to the flow of electrolyte during filling.

Plates: High Tin Pb alloy, optimized for high corrosion resistance.

Separator: Highly porous glass micro-fiber separator, optimized for low internal resistance. For maximum absorption of the electrolyte and for electrical separation.

Standard housing: Reinforced special high temperature resistant ABS container and cover adopted.

Terminals: Silver plated copper female insert for easy and safe assemble and maintenance free connection with excellent conductivity.

Valves: Release gas in case of excess pressure and protects the cell against atmosphere.

ELECTROLYTE FILLING – Special production and stringent QC systems are utilized to ensure the electrolyte saturation is optimized for each cell.

Measured high vacuum acid fill, reduces electrical variability between cells. The battery design and construction negates the need for electrolyte addition and the battery remains maintenance free throughout its design life.

SAFETY RELEASE VALVE – The battery will operate above atmosphere pressure under normal operating conditions, however the maximum pressure is governed by the safety one-way release valve. Open is activated by pressures in excess of approx. 2 PSI (14Kpa), resealing at approx. 1.2 PSI (8.4Kpa).

GAS RECOMBINATION – The gasses generated during normal operation of the battery are internally recombined. In fact more than 99% of the gas achieves recombination.

TERMINAL CONSTRUCTION – The contact quality between the insert terminal and the lead post is of vital importance during short duration/high amp dischargers.

Elevated terminal temperatures are the result of poor contact, eventually causing seal degradation and electrolyte leaks.

EverExceed’s design and assembly technique for terminal casting ensures trouble free operation for the design life of the battery.
