Description
Ritar RT12120 is a 12 V sealed lead-acid (AGM VRLA) rechargeable battery designed for reliable standby and backup power. It delivers 12 Ah of capacity at the 20-hour rate and features a maintenance-free, spill-proof design with absorbent glass mat technology for long service life. The battery supports high discharge currents (up to ~120 A for short bursts), has low internal resistance, and offers a design life of around 6 – 8 years in float service when used in standby applications such as UPS systems, emergency lighting, security systems, and medical equipment. Its compact form and wide operating temperature range make it versatile for a range of power backup needs.
Advanced AGM valve
With advanced AGM valve regulated technology and high purity raw material, the RT series battery maintains high consistency for better performance and reliable standby service life. It is suitable for UPS/EPS, medical equipment, emergency light and security system applications.
Self-Discharge
Ritar batteries can be stored for more than 6 months at 25 C. Please charge batteries before using. For higher temperature, the time interval will be shorter
