Energizer ECRN2025 CR2025 Lithium Coin Cell Battery

Product Description

The ENERGIZER ECRN2025 is a CR2025 lithium coin cell battery sold individually. It delivers the stable 3-volt output typical of lithium manganese dioxide coin cells and is designed for long-term, low-drain applications. This battery is commonly installed or replaced by HVAC technicians, electricians, and pool service professionals when servicing equipment that relies on coin cell power sources for memory backup, wireless remotes, or programmable thermostats. Its compact, flat form factor makes it a standard stock item for service vans and supply rooms.

The ECRN2025 suits a wide range of residential and light commercial applications. Coin cell batteries in the CR2025 form factor are found in programmable thermostats, HVAC system remotes, electronic manifold gauges, pool automation keypads, and small electronic control devices. This unit ships as a single battery, making it practical for individual replacement jobs without overstocking.

Key Features

Compatibility

Designed as a replacement for devices requiring a standard CR2025 lithium coin cell battery, including programmable thermostats, remotes, and electronic control accessories commonly found in HVAC, plumbing, electrical, and pool service applications.

Installation Notes

Coin cell battery replacement is a low-voltage task but always power down or place the host device in a safe state before opening the battery compartment to avoid unintended control signals. Note the polarity marking on the battery holder and insert the new cell with the positive side oriented correctly. Dispose of spent lithium batteries in accordance with local regulations, as lithium cells are not suitable for standard household waste disposal.
