Apollo 12V-18Ah AGM Battery

Apollo 12V-18Ah AGM Battery Prices in Bangladesh

The Apollo 12 V 18Ah AGM Battery is a premium, sealed lead-acid battery built for reliable, maintenance-free power delivery. Using AGM (Absorbent Glass Mat) technology, it ensures efficient energy storage, low self-discharge, and a rugged design that handles both float (standby) and cyclic use. This battery is ideal for UPS systems, alarm/security setups, telecommunications, emergency lighting, medical devices, and other critical applications.

Designed to withstand high demand, the Apollo 18Ah AGM can deliver a 270 A peak discharge for short bursts, making it capable of supporting power surges and sudden loads. Thanks to its sealed, non-spillable structure, the battery requires no refilling and offers safe and stable performance in any orientation. With a low internal resistance and heavy-duty grid construction, it reliably sustains power over long-term usage.

At roughly 5.00 kg, the Apollo 12V 18Ah offers a balance of capacity and portability. Its sealed construction and AGM technology support extended storage — retaining around 91% capacity after three months at room temperature. The recommended charging scheme (14.4 – 14.7 V for cyclic use, 13.50 – 13.80 V for float) ensures optimal performance and longevity.

Built to meet high standards, this battery follows the GP-series VRLA model design and is compatible with common 12V backup power systems.
