1254 60mah 3.7V lithium polymer battery bean cell with UL, KC, CB certification for gear fit iwatch TWS.
The advantage of this battery:
1. High density, 394Wh/L, can sure the device working in fluent way.
2. Long cycle life, 2c(120mah) 1.5h, and can do the cycling charge and discharge to 1200times ,
the remains still have 85%.
3. Good size consistency .OD is 12mm+0.1/-0.2,height is only 5.4mm+0.2/-0.1,
Like a nail size. And weight only 1.8g.

Part of factory view:
Waranty:
We give 1 year warranty. If the battery has problem coz of our quality issue, We will give replacement any time.
Q&A:
1. Q:How to start the cooperate?
A: Lets start with the sample orders. In 3-5days will be ready the samples, then you test.We make the standard according
the data sheet which we give.Once you confirm the quality, we can talk for further.
2. Q: How long to make the cargos?
A: Need 30day around if we dont have the stock of that model. Coz need strictly test and high temperature,high voltage life ageing as well in every single pc. That will takes a fixed date.
3. Q: What will be the packing?
A: We are using blister pallet packing in each battery. and then fold all packing in one ctn.
4. Q: Can the connectors be customized?
A: Yes, we can choose the right connector according your requirement.Or help to match your device.
