Advantages of Li Ion 18650 Battery Pack

It has the advantages of light weight, large capacity, and no memory effect, so it has been widely used. The energy density of lithium-ion batteries is very high. Its capacity is 1.5 to 2 times that of nickel-metal hydride batteries of the same weight, and it has a very low self-sufficiency. In addition, lithium-ion batteries have almost no "memory effect" and no toxic substances, which are also important reasons for their wide application.

Rechargeable Li Ion Battery 3.7 V 5200mah

Large capacity: The capacity of 18650 lithium batteries is generally between 1200mah and 3600mah, while the general battery capacity is only about 800mah. If combined into a 18650 lithium battery pack, the 18650 lithium battery pack can easily exceed 5000mah.

Long life: 18650 battery lifepo4 has a very long service life, and the cycle life can reach more than 500 times in normal use, which is more than twice that of ordinary batteries.

High safety performance: 18650 battery has high safety performance. In order to prevent battery short circuit, the positive and negative electrodes of 18650 lithium battery are separated. Therefore, the possibility of short circuit phenomenon has been reduced to the extreme. A protection board can be installed to avoid overcharging and overdischarging of the battery, which can also prolong the service life of the battery.

High voltage: The voltage of 18650 batteries is generally 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of NiCd and NiMH batteries.

No memory effect: It is not necessary to empty the remaining power before charging, which is convenient to use.

Small internal resistance: The current internal resistance of the 18650 battery that performs well is about 12 milliohms, and generally around 13-15 milliohms; since the impedance will affect the performance of the battery, generally speaking, 50 milliohms is normal. 50-100 milliohms can be used, but the performance begins to decline. When it is above 100 milliohms, it needs to be used in parallel, and it is basically unusable if it is greater than 200 milliohms.

To maximize the lifespan of your 18650 batteries, follow these tips

Avoid Overcharging: Use a charger with overcharge protection. Overcharging can reduce the battery’s lifespan.

Proper Storage: Store your batteries in a cool, dry place when not in use. Extreme temperatures can damage the battery.

Regular Use: Batteries that are regularly used tend to last longer. If you have a device that you rarely use, the battery might degrade faster.

Proper Charging Habits: Try not to let the battery drain completely before recharging. Lithium-ion batteries perform better when they are kept at a charge between 20% and 80%.

Usage Instructions

FAQ

Q: Why won't my 18650 battery charge?

A: Ensure that the charger is functioning and compatible with Li-ion batteries. Check the battery's voltage; if it's below the discharge cut-off, the protection circuit may have been triggered.

Q: Can I use a different type of battery charger?

A: No, you should always use a charger designed for Li-ion batteries to prevent damage.

Q: What should I do if my battery is overheating?

A: Stop using the battery immediately. Overheating can be a sign of internal damage or short-circuiting. Allow it to cool down in a safe area away from flammable materials.

Q: How can I safely dispose of 18650 batteries?

A: Do not throw them in the trash. Take them to a battery recycling center or a designated disposal facility.
