Power-Sonic TPPL Batteries

Thin Plate Pure Lead

The right battery for each layer of your data center.

Power-Sonic’s Thin Plate Pure Lead (TPPL) batteries are built for systems where power loss isn’t an option. These batteries support data centers, telecom infrastructure, industrial UPS systems, and other always-on applications that demand predictable performance and long service life.

Selmark supports Power-Sonic TPPL batteries across New England, providing application guidance, product selection help, and local follow-up.

What makes TPPL different

TPPL batteries use very thin plates made from high-purity lead. This design improves both float life and high-rate discharge performance compared to conventional VRLA batteries. All Power-Sonic TPPL batteries are sealed, maintenance-free AGM designs.

For always-on infrastructure, this translates to:

  • Longer service life and fewer replacements

  • Higher power and energy density in a smaller footprint

  • Stable performance during high-current UPS events

  • Sealed, maintenance-free AGM construction

Power-Sonic’s TPPL portfolio is intentionally split into two platforms to match how different backup systems actually operate.
