Concorde Battery Corporation manufactures Sun Xtender solar
batteries featuring Concorde’s sealed, valve regulated lead acid
(VRLA), absorbed glass mat (AGM) designs. Concorde's battery
technology has been proven and adopted by worldwide commercial and military users including the
U.S., Canadian, British, Australian and Italian Air Forces. Sun Xtender solar batteries are
application design specific, engineered and produced for consistent, dependable power requirements
for many demanding off-grid solar power systems.
The non-spillable construction of the AGM design allows Sun Xtender batteries to
be used upright or on their end or side. The maintenance-free AGM design means
no water replenishment ever. Utilizing pure lead-calcium grids, the plates are thicker than the
industry standard for longer cycle life, increased reliability and power.
The low-impedance AGM design allows for excellent charge
acceptance and there is no current limit required with controlled voltage charging.
As with the whole Sun Xtender® family, these new products feature Concorde’s proprietary
PolyGuard™ Microporous Polyethylene Separator that shields the positive plates
against shorting, shock or vibration. No other manufacturers offer this dual layer insulation
Sun Xtender® AGM solar batteries are engineered and produced for consistent,
dependable power for demanding remote off-grid solar power systems.
Sun Xtender battery covers and containers are molded with high-impact, reinforced copolymer
polypropylene and are designed with thick end walls to prevent bulging. The copper alloy “T”
Terminals and pure copper "L" Terminals are corrosion resistant and are
supplied with silicon bronze bolts and washers.
Sun Xtender providing safe, reliable and long lasting power since 1987. Hand Crafted for
Quality in the U.S.A.
All batteries with an "L" at the end of the part number like the PVX-2120L
are "L" Blade (solid copper) terminals. All batteries are supplied with silicon bronze bolts, nuts,
and washers required for installation.
All batteries with a "T" at the end of the part number incorporate M8 (copper alloy) threaded insert
terminals except as follows: PVX-340T & PVX-420T are M6.
Optional (Copper Alloy) Terminal Installed at the Factory: Batteries with a "T" at the end of the
part number (except PVX-340T & PVX-420T) are available with an optional factory installed "A"
SAE automotive type terminal by adding the appropriate suffix to the end of the part number. For
example, order PVX-1040TA instead of PVX-1040T.
Optional (Copper Alloy) Terminal Kit: Kits can be ordered for `After Factory` customer conversions of
"T" type batteries (except PVX-340T & PVX-420T) by ordering P/N 6918 for the "A" SAE automotive
post kit. Kit includes terminals and installation bolts required for installation.
Terminal Torque Values: [M6 use 35 in-lbs / 4.0 Nm] [M8 use 70 in-lbs / 7.9 Nm]
Handles: All batteries include built in lifting handles except the PVX-490T and
Ratings: Capacity ratings are after 15 cycles and are stated at 77°F (25°C) to 1.75
volts per cell.
