You're totally kidding. Large capacity is relative. If you use a 200MAH battery and say that the capacity of a lithium-ion battery is lower than that of a regular battery, are you kidding?
I have never seen a 200 MAH battery. The lowest I've seen is 400 MAH and the highest rechargeable lithium-ion battery is 3.2 Ah. I don't know what electrical appliances you use and I can't recommend a battery with the appropriate capacity. Lithium-ion batteries should be more cost-effective, but they are increasingly useless. people use disposable batteries. Less battery should have been recycled.
If you have any questions, answer me.
My industry provides technical support for lithium-ion batteries and power batteries. Let me help you solve the problem. If the answer is not good, give me some suggestions.
10440 (No. 7) lithium batterythium 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?
AA is the 5# pile and AAA is the 7# pile.
Ordinary dry batteries are not durable (now they are all mercury-free batteries, and there is no pressure on environmental protection), among which alkaline batteries have 4 times the capacity of ordinary batteries. The advantages are low price; easy to use ; easy to buy.
Rechargeable batteries are currently AA or AAA nickel-metal hydride batteries, which are also environmentally friendly. The disadvantages are low voltage, only 1.2 V each; a higher price; large capacity (than dry batteries);
Domestic Speedmaster, Energizer, Nanfu, imported Sanyo, Next Generation, etc. are more common.
If possible, it is best to uselithium-ion batteries: large capacity, low self-discharge, small body and light weight. After comparing nickel-metal hydride batteries, lead-acid batteries and lithium-ion batteries in digital cameras and electric vehicles, I have a better understanding.
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 discharge, the effective voltage range of lithium. Batteries are between 3.7V and 4.2V, the higher the voltage, the more power available. 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.
