Pros and Cons of Lithium and Lead Acid Batteries


Lithium batteries are relatively new to mobility scooters, and may eventually replace lead acid batteries as the market standard. But which is better? Below are the some of the pros and cons.


1. Weight.

The energy density of lithium batteries is much higher than that of lead acid batteries. That means for the same weight, lithium batteries can pack a lot more energy than lead acid batteries.


Therefore, mobility scooters can be built lighter so that they can become more portable. The lightest portable scooters that use lead acid batteries typically weigh about 45 - 50 kg, while those using lithium batteries weigh half as much.


2. Cost

Lithium batteries are more expensive than lead acid batteries, but lithium battery with a long life cycle (up to 3-5 years, LFP Batteries could even use for 10 years>.


3. Availability

90% of lead acid batteries used in mobility scooters come in 3 sizes: 12AH, 20AH and U1. They are all 12 volts, and are connected in series to power a 24V motor.

Tere's a pretty good chance of you can still find compatible batteries locally instead of shipping it from a far-away country or city.


Lithium batteries are custom-made to fit the particular model of scooter you have bought, it is quite easy to buy the batteries as well. 


4. Safety


Lithium phosphate iron batteries are safer than NMC batteries. 

Lead acid batteries is durable as well 


So if you are buying a lithium battery powered mobility scooter, it is best to choose reputable brands such as PLB batteries.
