Concorde
Sun Xtender batteries are sealed, maintenance free, valve-regulated, lead-acid batteries designed for deep-cycle PV applications. These batteries feature immobilized, non-spillable electrolyte in AGM microporous spun glass separators. The T series feature copper alloy insert terminals and the L series feature heavy-duty “L” blade terminals. Both are designed for heavy duty, high current capacities. Sun Xtenders have a wide range of operating temperatures from -40º F (40º C) to 160º F (72º C) as well as low self-discharge of approximately 1% per month at 77º F (25º C). UL recognized systems component.

Rolls Battery Engineering (by Surrette)
Rolls flooded, lead-acid batteries feature enveloped positive plates that are double insulated. This eliminates the possibility of separator misalignment, cracked separators, treeing or shorting at the bottom or sides. Each battery has an increased liquid reserve extending watering intervals, which means less maintenance. Each cell is assembled in its own inner container within a moisture tight, protective outer HDPE container minimizing short circuit potential. The rugged plate construction allows a long cycling service - the 4000 series for a
10-year average life and an 84-month warranty and the 5000 series for 15 year life and a 120- month warranty. The 5000 series is constructed in a dual container. For free freight allowance, contact us.
