If you search for "Nokia BL-30CH" online, you might encounter two vastly different answers. Some sources describe it as an "eco-friendly concept phone" made from 65% recycled plastic and 100% recycled aluminum; others identify it as a removable lithium-ion battery designed specifically for classic Nokia models. In reality, Nokia's naming convention reveals the truth: the "BL" prefix stands for "Battery for Li-ion." Therefore, the Nokia BL-30CH is a battery product, not a mobile phone model.
Online sources give conflicting technical data for the Nokia BL-30CH battery. According to Batteries Fast Blog, the genuine specification is 3.7V and 1500mAh, compatible with models like Nokia E72, Nokia E5 and Nokia C5‑00. Other sellers, however, advertise a 3.8V, 2900mAh high‑capacity version. This discrepancy likely results from different manufacturers using different cells or simply inflating capacity numbers for marketing. For buyers, safety certifications such as CE, UL and RoHS matter more than chasing the highest mAh figure.
Although the Nokia BL-30CH is primarily designed for the E72, E5 and C5‑00, its physical dimensions and connector type mean it can power other devices as well. If you own a portable radio, MP3 player, Bluetooth speaker or even a senior‑friendly audio player that uses a battery of the same size, voltage and terminal layout – the BL-30CH battery might be a perfect replacement. In other words, even if you don’t own those three classic Nokia phones, this battery could still bring new life to other small electronics around your home.
