History of the Narada VRLA Battery

OPzVEos & Acme & HRL

REX HTB12 ICS & 12VHTB

4

Acme series, developed based on Eos technology. “Acme” means “peak point”Special designed for outdoor cabinet initially.Increased structure for convenient installation and easy heat release.

Acme series where Narada grow up

5

Acme “S” series, developed based on ACME & MP technology Special designed for Telecom and UPS Application Increased structure for convenient installation and easy heat release.Improved Performance, Life, Cost, Dimension, Easy site Access Focus on Capacity from 12V 100AH to 12V200AH Improved Manufacturing Efficiency, Productivity, On time delivery

ACME “S” – 12NDT S
