The Icom BP-234 is a specialized lithium primary (non-rechargeable) emergency battery pack manufactured by Icom Inc. in Japan. Purpose-built for the Icom IC-GM1600E GMDSS handheld VHF transceiver, the BP-234 is a critical safety component designed exclusively for survival craft, lifeboats, and SOLAS-compliant emergency communication gear.

Encased in a high-visibility yellow, hermetically sealed shell, the battery utilizes advanced lithium chemistry to maintain a long shelf life (typically up to 5 years) and deliver dependable operating power under extreme sub-zero temperature conditions. Because it is a primary emergency cell, it is strictly intended for distress use and must not be recharged.

Key Features:
• SOLAS GMDSS Emergency Power: Certified emergency power source designed to meet strict IMO safety mandates for survival craft radios.
• Long-Term Shelf Life: Non-rechargeable lithium primary chemistry maintains charge reliability over years of storage in vessel grab bags.
• Extreme Cold-Weather Performance: Maintains stable operating voltage and output capacity in severe sub-zero marine environments (down to -20°C).
• Integrated Waterproof Gasket: Features a custom-molded orange sealing O-ring that maintains the IPX7 waterproof integrity of the host transceiver upon installation.
• Tamper-Evident Safety Design: Clearly labeled warning notices against recharging, incineration, or short-circuiting to prevent accidental misuse.
