TCTK batteries for laptops, cameras and tools

Devices they fit

TCTK batteries replace the original battery in laptops, cameras, camcorders, power tools, medical devices and household electronics. Each model is built to match the fit, voltage and capacity of the original.

Chemistry and formats

TCTK batteries are supplied in lithium-ion and alkaline chemistry, in cylindrical, prismatic and pack formats, depending on the device. Voltage and capacity are listed on the product label and in the declaration of conformity for each model.

36 months of warranty

Every TCTK battery carries a 36-month warranty.

Models with a product page

Each TCTK battery carries a QR code that opens the product page of that one model. Two models are published so far: TT-PH645L, a lithium-ion pack of 3.7 V and 1300 mAh, and TT-CR001L, an alkaline cell of 1.5 V.

Documents

Every model has a declaration of conformity and a safety data sheet. They are not published on this site yet — the documents section says how to ask for the ones you need.
