How to choose a battery for an electric wheelchair? Are lead-acid batteries good? Lithium battery is better

1. Product quotation:
The price of popular lead-acid batteries currently on the market is generally around 450 yuan, while the price of lithium batteries is more expensive, generally around 1,000 yuan.

2. Use period:
The service life of lead-acid batteries is generally about 2 years, while lithium batteries are more durable, and the service life is usually 4-5 years; the cycle system of lead-acid batteries is generally fully charged within 300 times, while the cycle system of lithium batteries is completely charged and discharged The frequency exceeds 500 times.

3. Quality volume:
In the case of the same volume, lead-acid batteries are bulky, much heavier than lithium batteries

4. Battery power:
Compared with lead-acid batteries, lithium batteries have a higher average working voltage and higher specific energy. In other words, lithium batteries have a larger capacity for rechargeable batteries of the same size.

5. Warranty period:
The warranty period of lead-acid batteries is generally 1 year, while the warranty period of lithium batteries is longer, which can be guaranteed for 2 years.

 

It may still not be intuitive by comparing some common characteristics of batteries.

Alright~ Brother God will directly compare the advantages and disadvantages of the two for you.

Advantages of lead-acid batteries:
Compared with lithium batteries, the price of lead-acid batteries is relatively cheap, the recycling price is higher than that of lithium batteries, and the charging and discharging characteristics of polymer batteries are stronger.

Lead-acid battery defects:
Lead-acid batteries are relatively heavy, and contain hydrochloric acid and some heavy metals exceeding the standard, which are corrosive and prone to air pollution; in addition, lead-acid batteries have lower specific energy, and their service life is not as good as lithium batteries.

Lithium battery advantages:
Compared with lead-acid batteries, lithium batteries are smaller, lighter, easier to carry, and have a relatively longer service life. In addition, lithium batteries have greater kinetic energy, can provide a large amount of current, and are more adaptable to high and low temperature tests, are less affected by temperature factors, and are more low-carbon and environmentally friendly.

Lithium battery defects:
The reliability of lithium batteries is relatively poor. If used improperly, there is a risk of explosion. In addition, lithium batteries cannot be charged and discharged at high currents, and the production standards are high, and the cost is also higher.
