Buying Guide

Match battery chemistry to your radio

Check whether your radio requires Li‑ion or Ni‑MH cells—Li‑ion typically offers higher energy density (e.g., 7.4V packs) while Ni‑MH is often compatible with legacy models

Confirm voltage and capacity

Verify the pack voltage (common 7.4V) and choose higher mAh for longer backup runtime—examples include 2700mAh and 2000mAh options

Prioritize model compatibility

Use manufacturer or model lists (for example, ICOM or Motorola model families) to ensure a replacement pack fits your specific radio form factor and connector

Evaluate value per mAh

Compare cost relative to capacity to judge value—higher mAh at reasonable cost improves backup duration without overspending

Consider pack count and redundancy

Multi‑pack options provide spare batteries for rotations and extended coverage, useful for frequent or long-duration use
