Whether to choose a lithium battery for a battery car or a lead-acid battery mainly depends on individual acceptance, because both batteries have their own advantages and disadvantages. Let's take a look at the pros and cons of both batteries:
1. Number of charging cycles
The number of full charges and discharges of lithium batteries is about 500 times, while the number of full charges and discharges of lead-acid batteries is only about 300 times. When charged once a day, the lifespan of lithium batteries is 4-5 years, while the lifespan of lead-acid batteries is only 2-3 years. batteries have a longer lifespan.
2. Charging speed
Since the activity of lithium in lithium batteries is relatively high, when charging, lithium batteries will charge faster than llead-acid batteries. It's fast. You may not notice it during normal use, but in an emergency, the importance of charging speed will shine through.
3. Endurance
The energy density of lithium batteries is 120 to 180 WH/KG and the energy density of lead acid batteries is 40 to 70 WH. /KG Therefore, for batteries of the same capacity, the energy density of lithium batteries will be higher, and one of the deciding factors in battery life is the energy density of the battery, so the Lithium batteries have a better lifespan than lead batteries. batteries.
4. Cost of use
Lead-acid batteries are mainly made of lead plates. The price of metallic lead is much cheaper than that of metallic lithium. Therefore, lead-acid batteries The price of batteries is generally lower thanthat of lithium batteries. Additionally, lead-acid batteries can be repaired, while lithium batteries are disposable. Therefore, in terms of future usage costs, it can be concluded that. Lead acid batteries are more economical than lithium batteries.
The real feeling of replacing lead-acid batteries with lithium batteries is that the vehicle battery life has been significantly improved and the charging speed is also much faster. The current mainstream in the market is lithium batteries, but. Due to the relatively high activity of lithium batteries, it is therefore necessary to charge outdoors when charging and not to charge indoors to avoid explosions or fires.
