What These Batteries Are
The PWL and PYL series are telecom-grade 12V VRLA AGM batteries engineered for stationary backup power. They are intended for applications where reliable float service, low maintenance, and long operational life are critical to system uptime.
These batteries are commonly used in telecom networks, UPS systems, data centers, power utilities, emergency systems, and other DC backup environments where dependable standby power is essential.
<>Choose These Batteries When
- You need a 12V VRLA AGM battery for a telecom, UPS, or stationary backup system.
- You are replacing an existing PWL or PYL battery and need the same family or equivalent format.
- You need telecom-grade batteries with long float-life performance and industry compliance.
- You need top-terminal or front-terminal options for rack, cabinet, or infrastructure applications.
- You want a sealed, maintenance-free battery solution for mission-critical backup power.
Consider Another Option When
- You need a cycling battery for frequent deep-cycle use rather than standby backup service.
- You require a different voltage, footprint, terminal style, or capacity than the PWL/PYL family provides.
- Your system calls for a specific approved battery model and compatibility has not yet been confirmed.
- You need a lithium-ion or alternate chemistry solution instead of VRLA AGM.
PWL vs. PYL: Which Series Is Right?
PWL Series: Best when longer design life is the priority. The PWL family offers super long-life performance with capacities from approximately 28Ah to 155Ah and design life up to 13 years in float service.
PYL Series: Best when you need a long-life telecom battery with broader higher-capacity options and a more cost-conscious selection path. The PYL family offers capacities from approximately 45Ah to 200Ah and design life up to 10 years in float service.
If you are unsure which family is right for your system, send us your existing battery model, runtime needs, or cabinet information and we can help narrow the correct option.
<>Key Features and Benefits
Telecom and critical power design
PWL / PYL batteries are built for stationary backup use in telecom and critical infrastructure applications where predictable standby performance matters. They are designed for systems that cannot afford unreliable reserve power.
Long service life
The PWL family offers up to 13-year design life, while the PYL family offers up to 10-year design life in float service. This makes them strong candidates for organizations looking to reduce replacement frequency and maintain long-term backup reliability.
Sealed AGM construction
These batteries use sealed VRLA AGM technology, providing maintenance-free, non-spillable operation well-suited for telecom and UPS environments. That helps simplify ongoing service requirements compared with watered battery systems.
Flexible installation formats
PWL / PYL batteries are available in top-terminal and front-terminal configurations to support different cabinet, rack, and infrastructure layouts. This makes them easier to match to existing backup power systems.
Built for demanding environments
These series are designed for tough industrial and telecom environments, with operating characteristics intended for extreme conditions and long standby service.
Industry compliance
The PWL and PYL families are built to meet GR-4228 and NEBS telecom standards, making them a strong fit for network and communications infrastructure applications.
