NP99sp NewPower99 Battery Kit for Microsoft Surface RT 1516 - Extended

Our review looks at the NP99sp NewPower99 Battery Kit for the Microsoft Surface RT 1516 and its single most important benefit: it revives an aging Surface RT tablet at a modest cost while including everything needed to complete the job. This kit is aimed at owners of the Surface RT model 1516 who want to replace a failing internal battery or keep a reliable spare. The inclusion of a 4250 mAh Lithium-Polymer battery, specialized installation tools and step-by-step video instructions makes the process approachable for a careful DIYer, and the one year guarantee adds a measure of assurance.

Key Features

• 4250 mAh Lithium-Polymer Battery: Provides extended runtime compared with a worn original cell, helping restore usable battery life to the Surface RT 1516.
• One Year Guarantee: Offers a full year of coverage so buyers have protection if the replacement battery fails prematurely.
• Includes Special Tools: The kit supplies the electronic tools needed for opening and replacing the internal battery, removing the need to source parts separately.
• How-to Video Instructions: A step-by-step video guides users through the replacement, reducing guesswork and the risk of improper installation.
• Kit Ready to Install: Everything required to revive the Surface RT 1516 is included in one purchase, making it convenient for at-home repair.

Who It's For

This kit is best for Surface RT 1516 owners who are comfortable with careful DIY repairs and want a cost-effective way to prolong the life of their tablet. It suits people who prefer repairing a device rather than replacing the entire tablet and who will follow video guidance and use the supplied tools.

It is not ideal for users who are uncomfortable opening electronics, who require manufacturer service, or who need the absolute fastest turnaround without attempting self-repair. Professional repair shops or users seeking a factory service option should look elsewhere.
