6 FAQs about [Battery charging with very small current]
Can You charge a battery with less current?
You can always charge a battery with less current. Heck you can even not charge it (no current). But if the battery wants to charge with more current than the adapter can handle, the adapter might overload. If it's a good adapter it will just switch off. If it's a crappy one it might catch fire. So your choice.
What is a standard charge on a battery?
A standard charge on a datasheet is typically defined as 0.5 C, where C stands for capacity. This means that the charge current should be half the battery capacity. For a 2500 mAh cell, the standard charge current would be 1250 mA. The battery cell will have most of its charge when the battery voltage reaches 4.1 V or 4.2 V.
Can a lithium ion battery charge at a low voltage?
A lithium-ion battery will still charge (slowly) at very low current. To avoid overcharge you must keep the voltage below 4.23V. Normally this is done by reducing charge current when it gets to 4.2V. I don't know what a 'shunt' battery charger is, but proper Li-ion charger IC's and modules are cheap and readily available.
How do you charge a lithium battery?
Typically, you charge lithium batteries by applying the CC-CV scheme. CC-CV stands for Constant Current - Constant Voltage. It denotes a charging curve where the maximum allowed charging current is applied to the battery as long as the cell voltage is below its maximum value, for example, 4.2 Volts.
How does an intelligent battery charger work?
An intelligent charger may monitor the battery's voltage, temperature or charge time to determine the optimum charge current or terminate charging. For Ni–Cd and Ni–MH batteries, the voltage of the battery increases slowly during the charging process, until the battery is fully charged.
What happens when a battery is fully charged?
At this point, the current going into the battery gradually decreases. When the current drops below a datasheet value, charging should be terminated. C/10 and C/30 are common charge termination current limits. When the battery is fully charged, the battery should be disconnected from the charger.
