## Description

**LONG WPL Series Long Life batteries**: extended-life AGM 6V/12V with 10-12 year float service life at 25 °C. 5-200 Ah for critical UPS, telecom and industrial backup.
Optimised lead-calcium-tin alloy and thicker plate. Direct equivalent to MK ESLR and other premium long-life AGM in the segment.

## LONG WPL — long-life AGM 10-12 year

WPL is LONG's premium line: same valve-regulated AGM chemistry as standard WP, but with 25-30% thicker plates and optimised Pb-Ca-Sn alloy. 10-12 year float service life at 25 °C vs 3-5 years for WP. Premium cost is justified where battery swap is expensive (lifts, hospitals, telecom).
Code V Ah Application

WPL55-12 12 55 Hospital UPS
WPL100-12 12 100 Telecom site
WPL200-12 12 200 Major industrial backup

### Critical applications

- Hospital UPS (theatres, ICU)
- 4G/5G base stations and telecom bridges
- Industrial backup where an 8-year failure is unacceptable

### **How much difference vs standard WP?**

2-3× longer life. WP lasts 3-5 years, WPL 10-12 — lower TCO when swap is costly.

### **Standard UPS charger compatible?**

Yes. Same AGM curve (13.6-13.8 V float, 14.4-14.7 V boost at 25 °C).
