Question

Once one reaches the peak voltage of a cell (say 4.2V), the battery can be charged further ? ​

Answer 1

=

Explanation:

Generally, a 3.7V lithium battery needs an overcharge and overdischarge protection circuit board. If the battery does not have a protection board, it can only be charged with a voltage of about 4.2V, because the ideal full charge voltage of the lithium battery is 4.2V, and the voltage may be damaged if it exceeds 4.2V.

Answer 2

Answer:

No, the battery cannot be charged further above the peak voltage.

Explanation:

• Placing a voltage across the terminals of a battery will cause it to charge.
• Things become challenging when rapid charging, safe charging, or maximum battery life are priorities. NiMH, NiCd, and Li-ion batteries are the three most prevalent types found in electronic gadgets.
• The C rate must be taken into account while establishing the charging settings for certain batteries. "C" stands for the battery's capacity after one hour of discharge.
• The cut-off voltage, often known as the minimum permissible voltage, is used to calculate these batteries' capacity.
• This voltage typically characterises the battery's "empty" state.
• The constant current regulator (CCR) battery charging circuit makes advantage of peak voltage detection.

Once the cell reaches the peak voltage, it cannot be charged further.
