18650CA-1S-3J Battery "Specified Charger"

Question

I've purchased the above battery to test it's viability for a product my company is designing. 18650CA-1S-3J BAK, Rechargeable Battery, 3.7 V, Lithium Ion, 2.25 Ah, Connector, 18.5 mm | Farnell UK

On the outside of the battery there's a label which states: "Use specified charger only". I can't locate this specified charger anywhere on the datasheet or anywhere online, only acceptable specifications for charging. Has anyone located the specified charger?

Has anyone used this battery in their own design? Did you use an off the shelf charger or embed your own charging circuitry into the design?

Hello,

I think you have answered your own question. The datasheet states charging specification, so a specified charger is one that follows the rules.

If you are building a prototype or some home-grown device you can use a ready made module like these:

If you are designing a final product, it is better (smaller, cheaper, ...) to embed the circuitry on your PCB with the consuming circuitry.
