Compatible replacement battery

The Cameron Sino battery fits Blaupunkt Bluetooth Lautsprecher models BT 202, BT 202 BK, BT202 and BT202BK. It matches the original INR18650 part number and delivers 2600mAh at 3.7V. A built-in protection circuit guards against overcharge, over-discharge, over-voltage and short circuit. The pack measures 66.00 x 22.50 x 18.60mm and weighs 49.0g.

Nickel-zinc chemistry limits

Nickel-zinc cells operate at a nominal 3.7V with a 2600mAh capacity, yielding 9.62Wh of energy. The chemistry requires a dedicated charger that respects the voltage window; using a low-quality third-party adapter can shorten cycle life. A new pack reaches full performance after two or three complete charge and discharge cycles. Storage above 60°C (140°F) is not recommended.

Upgrading from a depleted original

This pack replaces a worn-out Blaupunkt speaker battery that no longer holds a useful charge. The swap is worthwhile when runtime has dropped noticeably or the device shuts down under load. Installation is straightforward for anyone comfortable opening the speaker enclosure and reconnecting the factory connector. It is not for users who need a higher capacity than 2600mAh or a different voltage.

Questions about this item

How do I confirm this 2600mAh battery fits my Blaupunkt BT 202 speaker?

Match the part number INR18650 on your original battery and check the dimensions 66.00 x 22.50 x 18.60mm against the compartment.

What runtime can I expect from the 9.62Wh rating in my speaker?

At 3.7V the pack stores 9.62Wh; actual playtime depends on the speaker's power draw, so divide 9.62Wh by the device's wattage to estimate hours.

Does the nickel-zinc chemistry change how I should charge the 3.7V pack?

Use only the speaker's original charger or a quality 3.7V Li-ion charger; avoid low-quality adapters and complete 2–3 full charge cycles for best performance.
