The NEWMAX SG series is a 12 V sealed, maintenance-free solar GEL (VRLA) battery engineered for the frequent deep cycling of photovoltaic and renewable-energy storage systems. Its ThixoPure colloidal-silica GEL electrolyte, lead-calcium grids and Active Carbon plate additive deliver long cycle life, strong deep-discharge recovery and stable performance in partial-state-of-charge use. The non-spillable, position-free construction and flame-arrestor safety valves allow flexible, low-maintenance installation, and the range is offered in 12 V 100 Ah, 150 Ah and 220 Ah (C20) capacities.

Key features

• Sealed, maintenance-free GEL VRLA construction; non-spillable and position-free mounting
• ThixoPure colloidal-silica GEL electrolyte for extended cycle life and heat/cold tolerance
• Active Carbon plate additive improves charge acceptance in partial-state-of-charge solar use
• Low self-discharge: no more than 2% per month (6% after 3 months) at 25 C
• Flame-arrestor safety valve and high-rigidity PP case (140 C heat-deflection) for safety
• Built to IEC 60896-21/22, BS EN 61427 (PV) and KS C 8518 standards
