The difference between 1.2V and 1.5V rechargeable batteries is: 1.2V is a rechargeable battery and 1.5V is a non-rechargeable dry battery.
The potential difference between 1.2 V and 1.5 V batteries is different. Battery electrodes use different chemicals. The difference in electrode potential between H/H+ and Zn. /Zn2+ in the 1.5V dry battery is 1.5V, while the potential difference of the 1.2V electrode is 1.2V. In addition to the capacity, the battery also has a voltage indication.
1.2 V represents the average voltage during discharge. For example, the lithium battery is marked 3.7V, which also refers to the average discharge voltage. The working voltage of nickel-metal hydride and nickel-cadmium batteries is about 1-1.4V, and the average voltage is 1.2V. If it is less than 1V, it means discharge.excessive age. The specifications of lithium electronic batteries are mainly 3-4.2. V, and the average voltage is 3.6-3.7 V. The average voltage is 3.6-3.7 V. The higher the voltage, the higher the energy.
Precautions for using rechargeable batteries
Do not charge until the battery is exhausted. Many friends have the habit of recharging the battery after it runs out. For lithium-ion batteries, recharging after the battery is exhausted will cause the activity of the lithium element to decrease, which will affect the capacity of the battery and shorten its long-term life. term, which will cause greater damage to the battery.
It is not necessary for the battery to be fully charged. Regardless of the device the rechargeable battery is used on, do not fully charge the battery at once, as this will put more strain on the battery.terie and would affect its further use. Do not charge the battery unattended for a long time. For example, if the battery is charged here and people leave to do something else, it will last more than ten or twenty hours. Such long-term storage can easily pose security risks.
