Battery capacity is generally calculated in AH (ampere-hours), and the other is calculated in CELL (unit plate) several watts (W) 1.

1, the depth of discharge The depth of discharge is the extent to which discharge occurs during using 100% depth refers to the release of full capacity.

Following the four express delivery companies such as Yuantong and Yunda, another company received a “penalty” from the China Aviation Association On November 28th, the official website of the China Aviation Association issued a notice to clarify the qualification of the second class freight forwarder of Beijing Felix Logistics Co.

Lithium-based batteries are the fastest-growing battery system in the past 20 years and are now widely used in electronic products The recent explosion of mobile phones and laptops is essentially a battery explosion.

The laptop battery will self-discharge even if it is not used, so even if the fully charged battery is not used for a long time, this situation will occur In order to prevent the battery from being permanently damaged due to continued discharge when the battery is too low, the battery protection chip will be locked, causing the notebook to not recognize the battery, unable to charge and discharge, etc.

Lithium iron batteries are one of the batteries of lithium batteries The anode material is lithium iron phosphate, so it is called lithium iron batteries for short.

Now the cell phone battery is almost lithium battery New battery does not need to charge for 12 hours for the first time charging.

1, Mobile phone battery with cycle life between 20% and 80% has the longest battery life (this is the criterion for NASAspecial battery)2, that is to say, when the battery to start charging 20% of the time, don't deep discharge to 0%;At the same time when the battery charge to end around 80% of the time (80% for household are not good control, so just fill to 100%, remember and wash out in a timely manner will pull).

As the increasingly severe global pollution, energy conservation and environmental protection has become the task advocated by people all over the world How do we save energy? How do we work for environmental protection? We should start from daily use products.

We often charge electric scooter battery after running out of the power in our life; or remember to recharge the battery without fully charge when we need to use it suddenly Even forget to charge it for one or two months.
