A plethora of consumer electronics power lithium-ion batteries and even find their way into hybrid and electric vehicles. However, unlike regular alkaline and other batteries, replacing lithium-ion batteries for electronics can be very expensive.
Lithium-ion (Li-ion) batteries can be recharged, but rechargeable batteries cycle very short before thermalizing. It takes more time to start, and power is lost faster over time. Therefore, you can only replace or buy a new battery if you know how to confirm whether the lithium battery is discharged. Otherwise the gadget may be damaged. (David Asher).
All rechargeable batteries have a defined life cycle. Also, compared to new batteries, lithium-ion batteries retain only a fraction of their energy after multiple charges (usually after more than 200 days).
Definitely not normal for a battery that will only give you a few pictures. It may be dead. ——After charging a few times, it has reached the end of its life, or it is unreliable.
The manufacturer advertises no effect on lithium-ion batteries, so they can be refilled at any time, even if used for a short period of time. As long as it's fast charging, the timer that doesn't have time to recharge the battery will increase, so don't overcharge.
There are various ways to know if a lithium battery has reached its end of life, as follows:
Remove the battery, put the voltmeter on it, announce the voltage obtained, and put the battery inside.
No battery or no recharging after end of life.
The battery may swell slightly when it is dead or at the end of its life.
A battery that starts to heat up quickly is also one of the signs of the end of battery life.
The chemical energy accumulated in the battery is converted into electricity, which is passed from the battery to the light of the flashlight, indicating the end of the life of the lithium battery.
Rechargeable lithium-ion batteries come in many shapes and sizes. Lithium-ion batteries were originally designed in the 1970s and have since become the battery of choice for a variety of electronic devices, especially cell phones, laptops and computers. The life expectancy of about 2 to 3 years is the disadvantage of rechargeable lithium batteries. Lithium-ion batteries lose their ability to charge over time. That's why it's important to test lithium batteries from time to time.
The lithium battery test procedure is as follows.
Please deactivate the lithium-ion battery of the device. In most cases, the battery is connected to the charging device. Usually on the backplane. On a phone, for example, swiping the screen will do the trick. Some screws may need to be removed in order to gain access to other phones' batteries. The user's system documentation for the battery being checked must be reviewed.
Turn on the voltmeter.
Sets the gauge to measure in bolts.
Locate the positive and negative terminals of the Li-ion battery. Usually, they are at the end of the battery and are pushed into the usable system first. The terminal is small, but the signs are clearly marked with the symbols. Insert the corresponding positive and negative leads of the voltmeter into the battery terminals. The total charge (or bolt) is displayed on the scale on the instrument cluster.
Compare with the voltage listed in the battery manual.
Lithium-ion batteries provide protection circuitry that protects the battery from violence. This important precaution also shuts down the battery, which cannot be used once it is overloaded. Store the Li-Ion battery pack in a discharged state for any amount of self-discharge, slowly releasing the remaining charge, possibly slipping into sleep mode. The Li-Ion protection circuit switches between 2.2 ~ 2.9 volts/cell depending on the manufacturer.
Many battery chargers and analyzers have a wake-up or "boost" function that reactivates and charges sleep mode batteries. Without this condition, the charger will render the battery unusable and the battery pack will be discarded. Boost uses a smaller charging current to trigger a safety circuit, and when the proper battery voltage is reached, the charger starts charging regularly.
Do not use lithium-based batteries at voltages below 1.5 volts/cell for more than a week. A copper splitter has formed inside the battery and a partial or full electrical short may occur. Such batteries can become unstable while charging, leading to overheating or other abnormalities.
When charging the battery, make sure the polarity is correct. Advanced chargers and battery analyzers do not support loads if polarized. Voltage is not exposed to dormant lithium ions, so be aware. Lithium ions are more susceptible than other devices, and backpressure can cause permanent damage.
There is some confusion about lithium-ion battery storage. On the one hand, the manufacturer recommends maintaining a 40%-50% state of charge, and on the other hand, fear of losing it due to overcrowding. These requirements include adequate capacity. When in doubt, put the battery in a cooler place that provides higher power. This is how we wake up a sleeping lithium battery and use it again.
