It is difficult to distinguish them from their appearance. Because lithium batteries come in both block and cylindrical shapes, although dry batteries are mostly cylindrical and block shaped (9 volt laminated batteries). But it is easy to distinguish it from the words marked on the battery case: the voltage of dry cells is 1.5 volts, the voltage of nickel-metal hydride batteries is 1.2 volts, and the words NI-MH are marked, and the voltage of the alkaline batteries The batteries are 1.5 volts and the word LR is marked. The voltage of the lithium battery is 3.7 volts and that of the lithium iron phosphate battery is 3.2 volts. From these words you can tell whether it is a lithium battery, a nickel-metal hydride battery, or an alkaline battery.
How many types of watch batteries are there?
Many things in our lives require electricity, but everyone knows thatThe most commonly used batteries in our lives are ordinary batteries and lithium battery. But relatively speaking, what are the specific differences between ordinary batteries and lithium batteries? I think most people don't know this. With the development of modern high technology, it has become more and more convenient for everyone to travel. Every household will buy a small and light electric vehicle for themselves. If you haven't purchased one, you can see many shared electric vehicles available for rental. by the side of the road. So everyone Do you know how to choose an electric vehicle battery? ?
Ordinary batteries can be divided into carbon batteries and alkaline batteries, which are our most commonly used dry batteries, and hydrochloric acid batteries. So, what is a lithium battery? In fact, a lithium battery is a battery made up of un negative electrode material mixed with metallic lithium and other synthetic metals, then combined with a non-aqueous electrolyte solution. So, does everyone know the difference between regular batteries and lithium batteries? In fact, we use a lot of lithium batteries these days. For example, cell phone batteries are lithium batteries. Compared with ordinary batteries, lithium batteries have smaller internal resistance, so their service life will be better.
The question then is: if we want to buy an electric bike, what type of battery should we choose? Is it better to buy an electric car with a lithium battery or a car with a regular battery? Actually, I think this question is very simple. Everyone will understand that lithium batteries are of course better, even though most electric vehicles on the market are equipped withlead-acid batteries, which are ordinary batteries, compared to lead-acid batteries. Speaking, the lifespan of lithium batteries will be higher.
Lithium batteries can be charged and discharged more than 600 times, but if a lead acid battery reaches 600 charges and discharges, then I think the battery must be very tired. At that point, there must be a lot of virtual. electricity in the battery. Additionally, lithium batteries are lighter than lead-acid batteries, so e-bikes with lithium batteries will be lighter than e-bikes with lead-acid batteries.There are 5 models of watch batteries. These are: lithium battery, alkaline battery, mercury, solar energy, silver oxide.
Lithium battery: not only small in size, but also powerful, with a capacity of 3 volts, it can provide the maximume power and a short lifespan, which can be used in low-power watches, so it is very suitable for watches. These batteries can also be used in watches that have lights or other power-consuming features.
Alkaline battery: This is the most common type of watch battery and is a reliable and inexpensive battery. However, these only last a few months (up to six months).
Mercury batteries: Mercury watch batteries are generally smaller than lithium batteries, with a capacity of 1.36 volts. Their autonomy is equivalent to that of alkaline batteries, but their voltage is more stable.
Solar Cell: Environmentally friendly, the solar cell is powered by light arriving through the dial, meaning there are no batteries to replace. Solar cells contain none of the harmful chemicals found in conv batteriesentional and there is no need to worry about their elimination.
Silver Oxide Battery: Has excellent storage capacity and high performance. Additionally, batteries with a capacity of 1.62 volts share the constant voltage of mercury and are constructed the same way.
Watch battery model explanation:
Watch battery model explanation: The Swiss silver oxide battery model is 3xx, and the Japanese model is usually SRxxSW, or SRxxW (x represents an Arabic numeral). Lithium batteries are generally numbered CRxx.
In the IEC standard, the watch battery model R represents a cylindrical shape, L represents an alkaline battery, the number represents the battery size, and the P after the number represents high power. There is a special rule here. , which means ordinary No. 5. When zinc-manganese batteries are used, they should be marked R6P, not R06 or R6.
For example, 4.8x1.6mm337=SR416SW, 5.8x1.2mm335=SR512SW, 5.8x1.6mm317=SR516SW.
