About this replacement
Sony DCR-SR60 Series — 7.4V Li-ion Replacement Battery (NP-FV100)
This is a 7.4V, 2850mAh Li-ion replacement for the Sony NP-FV100 battery. It fits the DCR-SR60, DCR-SR62, DCR-SR68, DCR-SR68E, and over 49 additional Sony camcorder models that share the same NP-FV series battery slot. Capacity matches the original Sony specification at 21.09Wh.
- NP-FV series compatibility: These camcorders share the same 7.4V rail, multi-pin connector, and BMS handshake protocol across the DCR-SR and HDR lines. One battery architecture covers the full range because Sony standardised the FV slot across this generation of consumer camcorders.
- Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a DCR-SR68 body. The BMS communicated correctly with the camera, the remaining battery indicator updated normally, and the protection circuit tripped at the expected low-voltage cutoff without requiring a manual reset.
- First-use charge cycle on DCR-SR series: Charge this battery inside the camera body using the OEM AC adaptor before your first recording session. The DCR-SR BMS maps its battery-remaining display to the cell's discharge curve during that initial in-body charge — skipping it causes the indicator to read inaccurately for the first several uses.
Why the DCR-SR60 battery indicator drops suddenly near 40%
Sony's DCR-SR series uses a voltage-threshold method to estimate remaining charge rather than a coulomb-counting system. When a new cell's discharge curve doesn't match the camera's stored reference points, the indicator jumps or drops suddenly at mid-charge thresholds. This is most visible around the 40% and 20% marks where the camera checks voltage against fixed internal values. One complete in-body charge and discharge cycle recalibrates the threshold mapping and stabilises the display readout.
Camera body stays warm during extended DCR-SR60 recording sessions
The DCR-SR60 draws current simultaneously from the battery to power the image sensor, the recording mechanism, and the LCD panel during video capture. Under sustained recording, combined draw can push cell surface temperature noticeably higher than during standby or playback. This is normal behaviour for this camcorder class — it is not a fault with the replacement cell. If the body becomes hot to the touch and recording stops unexpectedly, check that the ventilation area near the lens barrel is unobstructed before resuming.
