Can be replaced, but battery voltage must be the same. Three dry cells can be connected in series to form a 4.5 volt battery. For conventional equipment powered by 3.7 volts, although the maximum battery voltage is 4.25 volts, the equipment will have a voltage margin of 5 to 10 percent. The -volt battery is yes, but it cannot be charged.
Why can't lithium batteries be the same size as AA batteries and AA batteries with a voltage of 1.5V?
As long as the voltage is the same or similar, in theory it doesn't matter which battery is used. You need to know what voltage your dv uses for power supply. For example: the DV battery is a #7 alkaline battery. If four batteries are connected in series, the voltage is 6 to 7 V.
Just use one with a similar voltage. Precision electrical equipment has its own circuitvoltage stabilization, so they may malfunction normally within a certain voltage range.
The voltage of a single lithium battery is 3.7 V! You need two online accesses. Mainly consider the two battery size factors.
It is recommended to use size 7 nickel-cadmium rechargeable batteries of 1.2 V/cell, so there is nothing to consider. Directly replace the AA alkaline battery.
Let me tell you that the electromotive force of the battery is determined by the material of the electrode, that is, a single battery. The nominal voltage of a standard lithium battery is 3.7V. So no matter the size and shape of a single lithium battery, its voltage is always 3.7V. Anything that changes, It’s capacity. This is why standard nickel-metal hydride rechargeable batteries only have 1.2V, regardless of size 5 or 7.
In fact, there are currentlya lithium iron phosphate battery. The voltage of a single battery is 3.2 V. It is shaped like a standard 14,500 battery (that is, a standard AA battery). and is associated with a reserved tube. It can be used instead of two ordinary AA batteries if the requirements are not very high.
