DEEP CYCLE Maintenance Free Batteries. These batteries are designed for backup/marine use only – not for daily SOLAR OFF-GRID charging/discharging, batteries never need water. Antimony-free plates cut electrolyte loss from gassing.
No filler caps – so no electrolyte contamination, overwatering or damage in use.
Unique wrought lead-calcium grid design means less internal corrosion and efficient current conductivity for more power and longer life. It also cuts gassing, resists overcharge, heat and thermal runaway.
Generous electrolyte reserve, factory checked for purity and specific gravity, is sealed in to last the service life of the battery.
