CR2016 battery

Introduction to the differences and usage common sense of CR2016 battery and lead-acid batteries

Lithium-ion battery: a battery with lithium metal oxide as positive electrode material, graphite as negative electrode material, and non-aqueous electrolyte solution; CR2016 battery are divided into lithium iron phosphate and lithium manganese oxide. Its capacity is 1.5-2 times that of nickel-hydrogen batteries of the same volume. It is widely used because of its high energy density and low self-discharge rate.

Lead-acid battery: a battery with electrodes made of lead and oxides and sulfuric acid solution as electrolyte; the important components of the positive electrode of the lead-acid battery in the discharge state are chlorine dioxide, and the important components of the negative electrode are lead; the important components of the positive and negative electrodes in the charging state are aluminum sulfate.

What the hell is 18650?

18650 is the originator of CR2016 battery. It is a standard battery model set by Sony Corporation of Japan to save costs. 18 means the battery diameter is 18mm, 65 means the length is 65mm, and 0 means cylindrical battery.

The advantages and disadvantages of CR2016 battery and lead-acid batteries are as follows:

Environmental protection: CR2016 battery are pollution-free, while lead-acid batteries are contaminated by heavy metals

Specific energy: the mass ratio and volume specific energy of CR2016 battery are about 40% higher than those of lead-acid batteries

Service life: the capacity of lead-acid batteries decays to less than 40% after 500 cycles of charge and discharge, while CR2016 battery can maintain about 85%

Discharge characteristics: for batteries of the same capacity, CR2016 battery can discharge about 30% more electricity than lead-acid batteries under high current discharge

Common sense for the use of CR2016 battery:

Battery use temperature environment references are as follows:

Charging environment temperature range: 0C-35C

Using environment temperature range: -10C-45C

Storage environment temperature range: 0℃-20℃

The available capacity references in different temperature environments are as follows:

-10C available capacity is 70%

0C available capacity is 80%

25C available capacity is 100%

Precautions for using CR2016 battery:

Please prevent the battery from being left idle for a long time

If you want to store the battery for a long time

Please keep the power at 50%~80% for storage, and remember to disconnect the air switch

The ambient temperature is kept at 0℃~20℃

And perform a complete charge-discharge process on the battery at least once a month

If the power is lower than 20% or higher than 90% for long-term storage

It will cause irreversible power decay in the battery

Do not place the battery in an environment above 40℃

To prevent irreversible capacity decay in the battery

Affect your normal use

In order to ensure the battery life and excellent performance

Please recycle it between 20%~90% as much as possible, and do not use it until it is automatically powered off before charging

During normal riding

Please operate the throttle handle slowly

When charging

Should be away from fire, radiators and other heating objects, and should not be covered by flammable items, and should be kept ventilated
