Replacement Ni-MH battery for Cobra radios

The Estry CP355 is a 3.6V 700mAh nickel-metal hydride pack built to match the original specifications for Cobra two-way radios. It suits users who need a direct drop-in power source for compatible handheld units without modifying the battery compartment.

Certified safety protections included

The cell integrates overcharge, over-discharge, over-voltage and short-circuit protection circuits that help extend service life and reduce risk during daily charging cycles. Compliance with ISO9001, RoHS, CE, UN38.3 and MSDS confirms the pack meets recognised safety and environmental standards.

Ni-MH chemistry and form-factor limits

Nickel-metal hydride chemistry delivers 2.52Wh of energy but self-discharges faster than lithium alternatives, so the pack benefits from regular top-up charges if the radio sits idle for weeks. The fixed 50.79 x 42.4 x 14.23mm footprint only fits the listed Cobra models; it cannot power devices that require a different voltage, connector layout or physical profile.

Questions about this item

When will the 700mAh Ni-MH pack need replacement?

The battery carries a one-year pack warranty; typical Ni-MH chemistry delivers several hundred charge cycles before capacity drops below useful levels.

What limits runtime during continuous transmit on the CP355 radio?

The 2.52Wh capacity and 700mAh rating set the energy ceiling; sustained high-power transmit will drain the pack faster than standby or receive modes.

Does the pack run hot or draw extra power during all-day use?

Ni-MH cells generate modest warmth under load but have no active cooling; the 3.6V nominal voltage and protection circuit keep power draw within design limits.
