Standard Terminals: All "T" batteries now incorporate low-profile copper alloy M8 terminals except the PVX-340T & PVX-420T which are M6. All batteries supplied with silicon bronze bolts, nuts, and washers as required for installation. No exposed lead terminals. This change was made to improve environmental safety and health. Optional Terminals: L Blade or Automotive post type terminals are available installed by adding the appropriate suffix: "L" for L Blade or "A" for automotive post. Handles: All part numbers include lifting handles except the PVX-490T, PVX-560T, and PVX-2240L. Ratings: Capacity ratings are stated at 77F (25 C) to 1.75 volts per cell.

Charge Procedures

Concorde Sun-Xtender Sealed, Valve Regulated AGM Batteries are charged at the factory and are ready for installation when they are received. While in storage they should be boost charged every 90 days or when their open circuit voltage falls below 12.5 V for a 12 volt battery, 6.25 V for a 6 volt battery and 2.08 V for a 2 volt battery.

Boost charge batteries using a regulated constant potential [constant voltage] charger, with an output of 14.1 to 14.4 V [for 12 volt batteries]. The battery is considered fully charged when the current drops to approximately 0.5 A for one hour.

Batteries that have not been boost charged and have been in storage for long periods of time [not more than 9 months] may need a conditioning charge. These batteries should be charged at the constant current rate [listed below] until the voltage remains constant or decreases for one hour or until the battery temperature reaches 115 F [46 C] while on charge.
