Going below this voltage can damage the battery. Charging Stages: Lithium-ion battery charging involves four stages: trickle charging (low-voltage pre-charging), constant current charging, constant voltage charging, and charging termination. Charging Current: This parameter represents the current delivered to the battery during charging.
It is safe to charge a low-current device with a battery charger only if it is designed to charge such devices. Most power banks are not compatible with low-current devices and treat them just like any other smartphone. This may cause them to send a high-intensity current which can damage your device.
Depends on the battery chemistry. For lithium ion, it's usually not a problem and can even be a benefit. For NiMH, a charging current that is too low can make it dificult for the charger to detect the point where the battery is full, which can lead to overcharging and overheating the battery.
At this stage, the battery voltage remains relatively constant, while the charging current continues to decrease. Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current.
A low current does not reduce life. The only way a low charging current might contribute to a reduced life is in the hands of an inexperienced designer who thinks that lithium cells behave like nickel or lead, and that if the current is low enough, then a gentle overcharge is permissible.
Charging Termination: The charging process is considered complete when the charging current drops to a specific predetermined value, often around 5% of the initial charging current. This point is commonly referred to as the “charging cut-off current.” II. Key Parameters in Lithium-ion Battery Charging

Constant-Current Battery Charger Circuit with Protection
Overcharge Protection: The circuit automatically stops charging once the battery reaches its full charge (e.g., 13.5–14.2V for a 12V battery). There''s no need to babysit—the charger has an internal shut-off switch. Deep-Discharge Protection: If the voltage drops too low (e.g., 11V for a 12V battery), an LED indicator warns you to recharge it.

S23 Ultra
One thing a good amount of ppl don''t consider about going from low battery to 100%, with even a brand new battery, is the heat that comes from it. The older a battery gets, the faster its voltage drops per amps consumed and so on normal usage, your battery gets hot more often. The same goes when charging up an older battery.
