Replacement Battery for Classic Nokia Handsets

The Cameron & Co DS-CS-NK4BML is a new lithium-ion cell rated at 3.7V and 700mAh. It replaces the original BL-4B and BL-4BA packs used in a long list of Nokia feature phones including the 1606, 2505, 2630, 2660, 2760, 3606, 5000, 6111, 7070, 7088, 7360, 7370, 7373 and 7500 models.

Fits Directly Into Existing Battery Compartments

The pack measures 46.50 by 34.30 by 5.20 mm and sits in the standard cavity without adapters or spacer shims. Its black casing matches the original aesthetic and the 2.59 Wh capacity restores talk and standby time without requiring a firmware update or a different charger.

Steady Output Across Extended Use

Lithium-ion chemistry delivers a stable voltage curve during long calls or days on standby rather than a sharp drop after a short burst. The 700 mAh rating replaces the earlier 750 mAh specification noted in the 2025.07 revision while maintaining full OEM compatibility for the supported handsets.

Questions about this item

How long will the 700mAh cell last before voltage sag cuts off my phone during a long call?

The 700mAh capacity delivers about 2.59Wh; actual talk time depends on the handset's power draw and signal strength, so expect shorter runtime in weak coverage.

Does the Li-ion pack run warm or draw extra current when the phone stays on standby all day?

Normal standby current is very low; the cell should stay near room temperature, but a faulty handset or corroded contacts can increase drain and heat.

Which Nokia models and original battery codes does this DS-CS-NK4BML replace?

It fits Nokia 1606, 2505, 2630, 2660, 2760, 3606, 5000, 6111, 7070, 7088, 7360, 7370, 7373, 7500 and replaces BL-4B and BL-4BA.
