In general, charging a battery more than necessary can adversely affect its safety and electrical characteristics. Continued discharge after cell voltage falls below the determined cut-off voltage. In general discharging a battery more than necessary can adversely affect its safety and electrical characteristics.
A lithium-ion battery is considered fully charged when the current drops to a set level, usually around 3% of its rated capacity. Some chargers may apply a topping charge to maintain the battery’s voltage without risking overcharging, which is vital for extending battery life. 2. Safety Considerations
The C-rating defines how quickly you can charge a battery. A battery with a 1C rating can be charged at a current equal to its capacity. For example, a 1000mAh battery can charge at 1000mA (1A). Charging at higher C-rates can reduce charge time. However, this may affect battery life.
It also changes according to the weather; a 12V car battery’s voltage falls in low temperatures. As a result, then, if you measure could be that your vehicle battery’s voltage is 12.5V and yet it’s actually fully charged. The same applies if your battery has been around the block a few times ie. it’s getting old.
Since this roughly corresponds to the actual usage limit, a battery that has fallen below this voltage is considered to have exceeded its service life. Amount of energy used in charging a battery. For constant current charging, this is the product of current and charge time.
If it is too high then it will overcharge the battery, but you might be able to add a voltage regulator to lower the voltage and limit the current to suit your battery. I'm assuming you're referring to lead acid chemistry. If the voltage (potential) is not greater then no current will flow, therefore it is impossible to overcharge.

Once the battery charger has been connected to the AC power supply, press the MODE button to select a different charging algorithm if required (the battery charger remembers the mode after disconnecting the power supply and/or battery).
First, there are problems associated with the fast charging of high-capacity batteries, which is known as high-power charging (HPC). Customers prefer the charging time of BEVs to be close to that of the ICE vehicles, which is approximately 8–10 min [3], to enable public charging such as at highways and supermarkets.Several major BEV manufactures have …
Continued charging after the cell has reached a fully charged state. In general, charging a battery more than necessary can adversely affect its safety and electrical characteristics.

1. Amp-Hours (Ah) Definition and Importance. Amp-hours (Ah) measure the total energy storage capacity of a battery. This rating indicates how much current a battery can deliver over a specific period. For example, a battery rated at 100 Ah can provide 5 amps for 20 hours before needing a recharge.; Higher Ah ratings typically mean longer run times for the devices …
The C rating measures a battery''s discharge rate relative to its capacity. This chart helps users select appropriate batteries for their devices. The chart displays various C …
The terminal voltage going down to 13.1v suggests the battery is not charging, and may be discharging, unless the battery is very low. The alternator or the battery is probably in poor condition. The alternator will charge the battery at a constant voltage (usually 13.8, or 14.2), and electively never a constant current.
Once off charge (disconnected) battery voltage may sag a little to ''rest'' voltage depending on battery type. If you charge a lead acid (car battery) at let''s say 14v, the battery will be at 14v while charging. After disconnecting, the battery will self-discharge back to 12.5v. To charge a battery you must supply enough current at a voltage that ...

If it is too high then it will overcharge the battery, but you might be able to add a voltage regulator to lower the voltage and limit the current to suit your battery.
The battery cannot be charged even after official reset procedure (via pinhole at the bottom of the laptop, holding "Power On" button for some time etc.) and after being on charger for several hours. Windows reports that battery is present, but it''s 0%, plugged in, not charging.
The only way I could correct the battery charge level was by going into the BIOS (pressing F2 on startup) and then go to: - Power Menu Item - Set Max Charge Level . And sent that ''Max Charge Level'' to 100%. Nothing in windows 11 to correct it. Cheers
A 12V lead-acid battery will not be damaged by overcharge if the voltage is kept low enough to avoid electrolysis, and the charging current is kept below 0.2C (5 times less than the Ah capacity).. Some types of lead-acid battery can handle higher voltage that others. SLA batteries must not be allowed to gas or they will lose water (which cannot be replaced) so they …
