MK Battery Backup Systems

MK Battery
VRLA-Gel
The MK Battery series of valve-regulated, gelled-electrolyte batteries is designed to offer reliable, maintenance-free power for renewable energy applications where frequent deep cycles are required and minimum maintenance is desirable. The sealed construction eliminates periodic watering, corrosive acid fumes, and spills. The electrolyte will not stratify so no equalization charging is required. Less than 2% per month standing loss means little  deterioration during transport and storage.
They are ideal for small to medium sized PV systems and are rated non-spillable by ICAO, IATA and DOT. These batteries feature polypropylene containers with handles and self sealing vents. They are constructed with lead-calcium plate alloy within sulfuric acid thixotropic gel. Terminal bolts included with all batteries. 2-year limited warranty. 5-year limited warranty is available.

Rolls Battery Backup Systems

Rolls
Series 4000 and 5000 Batteries
These flooded, deep-cycle batteries feature extended standard warranties and double insulated enveloped positive plates that eliminate the possibility of separator misalignment, cracked separators, treeing, or shorting at the bottom or sides. Each battery cell has increased liquid reserve levels resulting in fewer watering intervals. The 4000 Series is rated for a 10-year average life in cyclic applications and the 5000 Series is rated for up to 15 years. The 4000 series have rope handles, handles on 5000 series are molded into the outer case.
The 5000 series are constructed in a non-breakable modular dual container. Each 2-volt cell is
assembled in its own inner polypropylene container within a moisture tight, heavy-duty protective outer container eliminating damage during handling or possibility of short circuits due to water or falling metal objects. Series 4000 batteries carry a 24-month free replacement warranty (FOB factory) and include an 84-month adjustment period from date of installation. Series 5000 batteries carry a 36-month free replacement warranty (FOB factory) and include a 120-month adjustment period fromdate of installation (USA only).
