I want to design charger for that battery. I have found several charging ICs (for instance LT3650) that fit my design pretty well, but this IC terminate charging process at 1/10 of programmed charge current. In my case: 0.82A/10 = 0.082A what is about 1.5 times lower than 0.120A in battery specification. I confused a little with min charge

Battery Replacement
Battery charge current
The charging current will be dependent on the state of charge of the battery (the voltage difference between the charger and the battery). Use Ohm''s law: I = (Vcharge-Vbatt) / R. If the battery is nearly empty (around 3V), the current will be around 25mA and when it''s nearly full it will be almost zero.

6 Frequently Asked Questions about “Battery charging current is zero”
What causes a battery to stop charging?
Here are a few potential causes: Charging Port Issues The charging port itself may be faulty or loose, leading to intermittent charging. A faulty port may cause the charger to be recognized but fail to supply consistent power to the battery. Power Circuit or Charging IC The internal circuitry that controls charging may be malfunctioning.
Should you charge a battery before it hits 0?
Experts will encourage you to charge your battery before it hits zero. But if the worst comes to pass and your battery discharges completely, it won't respond when you connect a charger, at least not initially. The amp meter stay at 0 amps (or near it).
Why is my car battery stuck at 0%?
A faulty charger or charging port, a dead battery, outdated drivers or firmware, incompatible power management settings, overheating, and physical damage are all potential culprits that can disrupt the charging process, leaving the battery stuck at 0%.
What happens when a battery is fully charged?
The amperage on the meter will rise when the charging process starts. It may stay at zero when the battery is fully discharged. But eventually, the readings will increase. However, the amps will gradually fall as the charging process approaches the final stage. The amps hit zero once the battery is fully charged. 4). Dead Battery
How do I fix a battery not charging Windows 10?
Sometimes unknown glitches can prevent the battery from charging. An easy way to fix it is to power down your computer, hold down the power button for 15 to 30 seconds, plug in the AC adapter, then start the computer. 9. Disable Apps and Check Battery Usage in Windows 10
