Mobile Phone Batteries
Replacement batteries for mobile phones economically extend the service life of older devices and are available for models with replaceable battery (mostly older Android devices). Key specs: capacity in mAh (at least original capacity, higher for longer runtime), voltage (typically 3.7–3.85 V Li-Ion), connector type (model-specific). Quality features: CE certification, integrated protection circuit (BMS: over-discharge, overcharge and short-circuit protection), no fake capacity claims. External power banks (see Power Supplies) are the alternative for non-replaceable batteries.

Frequently Asked Questions
▶ How do I recognise a poor quality replacement battery? Warning signs: capacity far above original (e.g. 6,000 mAh for a device with 3,000 mAh original), no CE mark, no BMS protection circuit, very low price (<5 EUR). Reputable brand manufacturers (Cameron Sino, Varta, Ansmann) state realistic capacities and supply CE-certified batteries with BMS. |
▶ Can I install a battery with higher capacity? Only if the device housing has sufficient space and the connector is identical. Some manufacturers offer extended batteries with larger capacity supplied with a special thicker back cover. Never install a battery with higher voltage or incompatible connection – fire hazard. |
▶ How do I dispose of old mobile phone batteries? Lithium batteries must not go in household waste. Legal obligation (BatterieG, EU Battery Regulation 2023/1542): return to retailers (mandatory for all battery sellers), at municipal collection points (recycling centre) or manufacturer take-back systems (GRS, Eucobat). For particularly safe disposal: seal battery in plastic bag (prevents short circuit if damaged). |
