I put the Li-ion battery purchased on Aliexpress. Measured capacity 650 mah.
Built-in PCB protects against overcharging at 8.44 volts, and against overdischarge.
It is perfectly charged by the built-in charging of the meter U1252A and there is no danger of overcharging.
In the photo the charge limit and the type of viscera.

I took a year ago, 2 pcs at a discount for 10 USD this product. Now the price is about 7 USD for 1 pc.

I found my review to the seller for this purchase:
Quote
600-650mAh battery instead of the declared 1000mAh. This is very bad. In the photo measurement. Discharged with current 150 mA fore disconnecting with built-in protection at 5.72 volts. Charged with an initial current of 150mA with a voltage of 8.47 volts. When charging / discharging 8.4-6.0V, the capacity will be approximately 0.6Ah, so be careful that it does not bulge. Protection shuts off charge at 8.52 volts. Overcharge / discharge protection works. Inside there are two cans of Li 722337 and a protection board. In general, everything is fine, except for capacity. Buy and return on the dispute about 40%.
