[ONE Accessories] restartoshi:
I have used ReplaceBase OPO “OEM” battery over the month, here is my update.

Capacity: (Accubattery)

The battery is very stable, as you see the attachment, the most of capacity shows over 2900mAh with AccuBattery. Interestingly the capacity is getting better recently. Accordingly the Estimated Capacity increased from 95% to 96% recently. Today, after 39 charging sessions, the capacity reaches 3100mAh first time. (I have no idea why this happens, it is the battery’s characteristics or Accubattery’s behavior)

Charging Speed

Charging Speed is extremely fast 2075mA at peak with my Choetech SMT0008 5V/2.4A charger and Tronsmart 1.8m 20AWG usb cable. (3 years Old original OPO battery got 1850mA at Peak)

Stability

I charge ReplaceBase battery up to 80-85% and I am able to use until 2-3% without any problem. As I said before, the fake Aliexpress OPO battery shut down around 10-15% temperamentally. I can say that the battery is pleasantly stable.

High Quality Battery Cell made by Lishen

I have found that the battery cell is produced by Lishen. (See the photo) Lishen is the leading Chinese battery manufacturer

Through my own experience, I believe that this is the genuine Lishen high quality battery. The quality of the battery cell is the one of the most important factor for a long time use.

Edit 20/8/2018

I have just found the Listen cell information SP435881SE-C , used by this battery.

Temperature Sensor

It does not work; I have found that it shows 24.9 degree and 25.0 degree only. This is a typical non OEM characteristic. I am not surprised if this Lishen battery cell is used by the original OPO OEM battery, but BMS board is not OEM. I have contacted to ReplaceBase about this issue. ReplaceBase will try to get more information from the supplier. I am waiting for any reply. I am wondering why this high quality battery does not have the temperature Sensor as well. Is it expensive, or Proprietary?

May I recommend this?

I understand that the temperature Sensor does not work. Still I would recommend this battery because of the Battery cell quality at very reasonable price. In addition, I think that ReplaceBase is very honest and genuine. The battery (and Custom Rom!) will give your smartphone a new life! I really feel so after replacing the battery. Temperamental reboot (!) is gone after replacing with this new battery, no more worry at 15 % battery capacity. I am confident to use my OPO for another a couple of years at least.

Final Thought: Fake Battery capacity - Check the weight!

I have tested a fake Aliexpress battery; (see my previous post) frankly I feel that it is no point to make a comparison among Aliexpress OPO batteries, which uses low quality generic battery cell. I have researched some notebook batteries before. Cheap fake battery uses smaller 1800mAh 18650 batteries instead of 2500mAh for instance. If the battery uses smaller fake capacity, there is no reason to trust the quality. This is the bottom line. So check out your OPO battery weight. If your OPO battery has only 45gram, then fake capacity. You have no reason to trust the battery!
