Lead Acid Battery 12V120ah AGM Maintenance Free Solar Power Storage Battery

Product Description

Lead Acid Battery 12V120Ah Maintenance Free Solar Power Storage Battery

Sunstone ML series battery is 12V valve-regulated maintenance-free energy storage battery that adopts advanced adsorption glass fiber cotton sealing technology and is a mainstream energy storage power supply product in the industry. Relying on high-purity lead material and precise production processes, the battery has lower internal resistance and stable discharge performance. It features core advantages such as sealed leak-proof, maintenance-free, high safety, and long durability, completely eliminating the pain points of traditional lead-acid batteries such as frequent water replenishment, leakage corrosion, and acid mist evaporation.

The product adopts a fully sealed flame-retardant shell and an intelligent valve-controlled pressure relief structure. It is shock-resistant, jolt-resistant, and can withstand high and low temperatures. It has extremely strong environmental adaptability and can be safely used in various scenarios such as indoor closed Spaces, vehicles, and outdoor cabinets. It is not afraid of tilted placement or slight jolts, and there are zero risks in transportation and installation. At the same time, the battery has a low self-discharge rate and excellent static storage capacity, meeting the dual demands of both regular standby and cyclic use. It not only has strong high-current discharge and stable load-carrying capacity, but also has outstanding deep discharge recovery performance, effectively extending the service life.
