String Count Reduction to Reduce OpEx - You can use fewer AlphaCell HP batteries compared to
standard batteries, while maintaining network runtime reliability. For power supply loads that are less than 8 Amps you can achieve a 4 hour runtime using a single string of 4.0HP batteries compared to using two strings of competitive batteries. Consult your Alpha sales engineer for a free network analysis on how to potentially reduce your OpEx by up to 25 percent while increasing the reliability of the batteries in your network.
