Do You Ever Care For Lithium-ion Battery During Using?

As we all know, lithium-ion battery is much more longevity than lead acid, it is really a better battery for battery storage for us to choose. But during working, users may complain that lithium-ion battery is also easily broken or shorter lifespan, same with lead acid. Do they waste the money to choose? is the lithium-ion battery not that better? We really not well know how to do lithium-ion battery care and allow the battery to operate efficiently. Here are a few ways to keep your lithium-ion batteries healthy.
1: Keep your batteries at room temperature
That means keep batteries or storage batteries in between 20 and 25 degrees room. The worst thing that can happen to a lithium-ion battery is to have a full charge and be subjected to elevated temperatures. Too low or too high temperature is by far the one of largest factor when it comes to reducing lithium-ion battery life.
2: Think about getting a high-capacity lithium-ion battery, rather than carrying a spare
Batteries deteriorate over time, whether they're being used or not. So a spare battery won't last much longer than the one in use. It's important to remember the aging characteristic when purchasing batteries. Make sure to ask for ones with the most recent manufacturing date.
3: Allow partial discharges and avoid full ones (usually)
Unlike lead acid batteries, lithium-ion batteries do not have a charge memory. That means deep-discharge cycles are not often required. In fact, it's better for the battery to use partial-discharge cycles.
There is one exception. Battery experts suggest that after 30 charges, you should allow lithium-ion batteries to almost completely discharge. Continuous partial discharges create a condition called digital memory, decreasing the accuracy of the device's power gauge. So let the battery discharge to the cut-off point and then recharge. The power gauge will be recalibrated.
4: Avoid completely discharging lithium-ion batteries
If a lithium-ion battery is discharged below 2.5 volts per cell, a safety circuit built into the battery opens and the battery appears to be dead. The original charger will be of no use. Only battery analyzers with the boost function have a chance of recharging the battery. Also, for safety reasons, do not recharge deeply discharged lithium-ion batteries if they have been stored in that condition for several months.
5: For extended storage, discharge a lithium-ion battery to about 40 percent and store it in a cool place
I've always had an extra battery for my notebook, but it would never last as long as the original battery. I know now that it's because I was storing the battery fully charged. That means oxidation of lithium-ion is at its highest rate. Storing lithium-ion batteries at 40 percent discharge and in the refrigerator (not freezer) is recommended
To include the above five tips, lithium-ion battery care is very important to increase its lonevity, keep lithium-ion battery in room temperature, or make sure to have temperature protection system to battery, or improve the BMS with temperature protection function; Don't full discharge lithium-ion battery often, and make sure charged full at every time. To learn these tips, when you choose lithium-ion battery, we need to calculate how much capacity need for the system and where to install and storage.
