Lithium battery packs and lead-acid batteries are the two batteries that everyone likes to compare with. A little bit of engulfing, lithium battery pack is the development of the trend of the trend, has been chosen and accepted by the majority of customers.
Today we are going to discuss a problem, the same capacity lithium battery pack and lead-acid battery, who goes further?
It is understood that the internal resistance of the lithium battery pack is slightly larger, the discharge curve is stable, and the front and rear speeds are evenly balanced;
The lead-acid battery has a small resistance inside the cylinder, and the speed is fast when starting, but it will be more competitive with the voltage drop speed. The two will only fight from the discharge curve and the journey, and the lithium battery pack will be slightly longer.
For example, it is determined that the discharge of lead-acid batteries can be reduced by some mileage. When the battery is discharged, the electrolyte is agilely diluted, and the lead sulfide molecules in the solution of more than 90% of the pores in the plate are too late to diffuse. In the vacancy position, the solution in the plate hole is added to the resistor, and the terminal voltage drops. The quality of the lithium battery pack of the same capacity is only 1/5-1/10 of the lead-acid battery, so the lithium battery The package is farther than the lead-acid battery mileage is certain!
Let's compare the lithium battery pack with the lead acid battery in detail:
1. Lead-acid battery has low cost, strong and mature receiving and receiving mechanism, low internal resistance, low working premise, no need to care for the circuit, almost no maintenance, it is based on bad conditions. Lead-acid batteries, not lithium batteries, such as car starter batteries, field generator start batteries, today's popular electric car batteries, UPS power batteries, etc....but there are also lower capacity, quality, and volume. Charging this number is low, and in the future, with the growth of lithium batteries, the way the lead-acid battery is getting narrower and narrower is certain.
2. The benefits of lithium battery packs must have personal experience, notebooks, mobile phones and all kinds of digital products, now all standard lithium battery packs! Until now, there is still no battery that can span in terms of capacity and number of charges. Lithium battery pack, especially ternary lithium battery, although BYD's lithium iron phosphate battery is more secure, but the difference in capacity can only leave a part of the security problem behind.
It is a good choice for the battery pack, and now the battery management unit is gradually improving. It is getting better and better for battery care, balance and heat management. Of course, you don’t think that the popular lithium battery for electric vehicles is hot. Handling...will not be there, only on the electric car, the balance of the custom lithium battery pack is better, thank you!
In addition, to understand the use of lithium battery packs:
1 We must also pay attention to the process of using lithium batteries, do not often let it over discharge;
2 charging should also be careful not to mix with lead-acid chargers;
3 It is not a professional who should not dismantle the lithium battery pack by himself. Other special attention should be paid to the fact that some types of lithium batteries will suddenly decline when the low current use voltage is too low, that is, the charge cannot be saved back;
4 Don't idle for a long time or charge for a long time. This is the same as the lead-acid battery care. If it is too long, the battery will be discarded.
5 temperature should be suitable, lithium battery pack charging temperature is 0 ° C ~ 45 ° C, lithium battery discharge temperature is -20 ° C ~ 60 ° C;
6 In a clean, dry, ventilated environment, avoid contact with corrosive substances, away from fire and heat.
Choose the same capacity lithium battery pack and lead-acid battery, lithium battery pack mileage is farther is certain!
