Cameron Sino Replacement Battery

This Cameron Sino replacement battery is designed for the SRS-BTX300, SRS-X55 and SRS-X77 models. It uses high-quality cells to deliver reliable power and extended service life. The unit meets or exceeds original specifications for a secure fit and consistent performance. Installation is straightforward, allowing users to restore device function quickly.

Practical Limits of Portable Power

A replacement battery restores runtime but cannot increase the original capacity designed into the SRS-BTX300, SRS-X55 or SRS-X77. Performance will degrade naturally over charge cycles and with age. It does not add features such as faster charging or higher output than the device was built to accept. Buyers needing longer runtimes than the original design allows will not achieve that with this part.

Compatibility Decides Fit

The only specification that determines whether this is the correct part is the exact model number of your device. This battery fits the SRS-BTX300, SRS-X55 and SRS-X77 only. It is not suitable for any other jump starter, charger or portable power unit. Verify the model label on your equipment before ordering to avoid a mismatch.

Questions about this item

Which model should I choose among the SRS-BTX300, SRS-X55 and SRS-X77?

Select the battery that matches the model printed on your jump starter — SRS-BTX300, SRS-X55 or SRS-X77 — because this replacement is built to fit each of those exact units.

What does the SRS-BTX300 designation mean once the battery is installed?

It identifies the jump starter this cell is engineered for, so the replacement restores the original runtime and cranking capability of that specific unit.

What connection standard does this battery use and what does it limit?

The pack uses the proprietary connector shaped for the SRS-BTX300, SRS-X55 and SRS-X77, so it only works with those models and cannot be adapted to other devices.
