Cameron Sino replacement battery for Surface 1769, 1782

Replacement Battery for Surface 1769 and 1782

This Cameron Sino battery is a direct replacement for Microsoft Surface models 1769, 1782 and 2-LQN-00004. It uses premium-grade cells to restore the original runtime and charge-cycle life. The design matches the factory dimensions for a secure fit without modification. It suits users who need to revive an ageing tablet for daily mobility.

Limits of a Single Internal Cell

A single internal pack cannot be hot-swapped, so the device must be powered down for installation. Capacity is fixed at the original specification, so runtime will not exceed the factory rating when the tablet was new. Degradation over time is normal and will eventually require another replacement. Users who need continuous uptime without shutdowns cannot rely on this part alone.

Upgrading From a Worn Original Pack

This replaces a battery that no longer holds a useful charge or that shuts down under load. The jump is worth it when the tablet otherwise functions but tethered to a charger. It is not for buyers who want more storage, a higher-capacity pack than stock, or a device that supports user-swappable modules. If the charging circuit or mainboard is faulty, a new cell will not fix the issue.
