Cameron Sino BRV-1M 3400mAh 12.58Wh nickel-zinc standard battery

Direct replacement for Braven BRV-1M

This nickel-zinc battery matches the original 3.7 V 3400 mAh 12.58 Wh specification and fits the 66.60 x 21.00 x 18.60 mm compartment. A fully decoded chip reports charge status exactly like the factory cell, so the speaker’s fuel gauge remains accurate without recalibration.

Low self-discharge chemistry runs cool

Nickel-zinc cells generate minimal heat during typical playback volumes and hold voltage steadily until the protection circuit cuts off at the safe lower limit. The integrated circuit guards against over-charge, over-discharge, over-voltage and short circuits, keeping internal temperature stable during long listening sessions.

Swaps the ageing pack in a BRV-1M

When the original cell no longer holds a full day’s charge, this unit restores runtime to factory levels. The jump is worth it if the speaker still sounds good but shuts down early; it will not help if the driver or charging port is damaged.
