How long does it take to charge an AA rechargeable battery?

There are many types of AA batteries, so you need to look at what type of battery it is and treat them differently.

Ordinary batteries cannot be charged, so rechargeable batteries are required.

The rechargeable battery should be fully charged for the first time: 8 to 16 hours. Now 2 to 4 hours will be enough. Nickel batteries must be recharged after being discharged. Lithium batteries should not be discharged frequently, which is not good for the battery. There is no harm in charging lithium batteries in stages without memory.

10440 (No. 7) lithium battery 3.7V is the output voltage, 4.2V is the charging voltage. Why does the battery I purchased measure 4V with a multimeter? Are you looking for a solution?

It's going to break. When carbon batteries are stored for a long time, the power will decrease, the more humid environment swill be faster, the faster the low discharge will be. If you sit it for a long time, for 5 or 10 years, it will eventually discharge one day, then swell, break, undergo an acid reaction and finally leak. A dry environment will prolong the above phenomenon.

Under normal circumstances, it can be stored for 1-2 years. It can be stored in a dry and cool place. It can be wrapped in wax paper or plastic wrap. battery, with one year, one month and one day. The general shelf life of Fu batteries is 3 years. But electricity consumption does not remain unchanged for three years. It's just that new batteries deteriorate slowly. After 3 years, they can deteriorate rapidly until they run out of energy.

Detailed Information

Battery Knowledge

AAA is what we usually call AA battery. The general size is: 11mm in diameter. height 44mm. ?

AA is what we usually call the AA battery. Its general size is: 14mm in diameter and 49mm in height.

Primary battery (primary battery): A battery whose active material can only be used once. Such as zinc-manganese batteries, alkaline-manganese batteries, silver-zinc batteries, lithium-manganese batteries, etc.

Secondary battery (storage battery): A battery that can be recharged and reused after being discharged. Such as lead-acid batteries, nickel-cadmium batteries, nickel-metal hydride batteries, lithium-ion batteries, etc.

Fuel cell: A battery in which an active material is continuously supplied to the electrodes from the outside.

The rated voltage of lithium batteries is generally 3.7V, and 4.2V is the charging limit voltage, that is, the maximum charging voltage cannot be greater than 4.2 V. During dischargearge, the effective voltage. The voltage range of lithium batteries is 3.7V. Between -4.2V, the higher the voltage, the more sufficient power. When the lithium battery voltage is lower than 3.7V, the device will shut down quickly due to insufficient power. Your battery measurement is 4V, which means it is in good storage condition and has enough power.
