If your lithium battery shows 40% charge remaining, but the device shows no signs of life, there may be several possible reasons:
1. The device may be in sleep mode: some devices can do this. Switch to sleep mode when the battery power drops below a certain level to protect the battery charge.
Solution: Try pressing the power button to restart the device, or connect the charger and wait a while to see if the device restarts.
2. The battery may be damaged: Lithium batteries have a limited lifespan and may be damaged after long-term use.
Solution: Try replacing the battery. If the device works normally after replacing the battery, the problem is probably caused by a damaged battery.
3. There may be a problem with the charging cable or charger: the charging cablearge or charger may not be able to properly power the device.
Solution: Try using a different charging cable and charger to see if the device works properly.
4. The device may have other defects: In addition to the above problems, the device may have other hardware or software defects.
Solution: If none of the above solutions work, it is recommended to contact the device manufacturer or repair center for further troubleshooting and repair.
Please note that the above reasons are only common reasons that may cause the device not to turn on. The specific situation may vary depending on the brand, model and operating system of the device. If none of the above solutions resolve the issue, please seek professional technical support.
How to distinguish lithium batteries from batterieslead ??
60V refers to the rated voltage and 40ah refers to the capacity.
Multiplying the two gives 60 V × 40 Ah = 2,400 Wh, which is equivalent to 2.4 kilowatt hours or 2.4 kilowatt hours of electricity.
That is to say, the storage capacity of this lithium battery has reached 2.4 kilowatt hours. If used on a regular electric vehicle, it can travel about 100-110 kilometers.
Lithium batteries: lightweight, high specific energy, but poor safety and low cost performance; lead-acid batteries are heavy, large in size, low specific energy, but good safety and high performance. .
How to correctly distinguish lead-acid batteries and lithium batteries:
Battery capacity
The capacity of lithium batteries is generally 8 to 10 A, and that of lead-acid batteries The capacity is about 20A.
In terms of kilometers parrun
For example, with the same 48V battery, when fully charged, electric vehicles equipped with lithium batteries and lead-acid batteries can travel 30 to 40 kilometers. its speed depends mainly on the size of the motor used.
In terms of durability
(1) Lithium batteries have strong durability, slow consumption, can be charged and discharged more than 500 times, and have no memory . 4-5 years. Lead-acid batteries generally have a memory of less than 400 deep charges and discharges and have a lifespan of approximately two years. If you are using maintenance-free lead-acid batteries, it should be noted that the battery loses less water and it is generally not necessary to add distilled water when using it.
(2) In terms of durability, lithium batteries have good vibration resistance. The fully charged battery is solidly ffixed and vibrates at an amplitude of 4 mm and a frequency of 16.7 Hz for 1 hour without leakage or battery. Expansion and rupture, open circuit voltage is normal; good overcharge resistance, 25 degrees Celsius, battery fully charged 0.1 AC for 48 hours, no leakage, no battery expansion or rupture, open circuit voltage is normal, battery maintenance rate capacity is greater than 95%. ; It has good resistance to large currents. When the fully charged battery is discharged to 2CA for 5 minutes or 10CA for 5 seconds, no conductive parts will merge and there will be no appearance deformation.
In terms of price and warranty period
The most common battery currently on the market is 48 volts. If it needs to be replaced, lead-acid batteries cost about 380-450 yuan (48V12AH-48V20AH), and the warranty period is 1 year; lithium batteries are relativelyent expensive, costing around 1,000 yuan (48V12AH), but their warranty period is 2 years.
In terms of price and warranty period
The common battery on the market is 48 volts. If it needs to be replaced, the lead acid battery is around 450 and warranty. the period is 1 year; lithium battery price. It is relatively expensive, costing around 1,000 yuan, but its warranty period is 2 years.
