How to choose between lithium and lead-acid batteries
- Nov 14, 2018 -

Lithium ion batteries have been a craze long, but do they really outperform traditional lead-acid ones in every aspect at present. Absolutely the answer is No. Below is an overview of the two battery types. 

Lead-Acid Batteries

Pros

  • Lead-acid batteries have spreaded wide because of their affordability.

  • They are reliable and tolerant to harsh conditions.

  • Though deemed dangerous when it comes to the material, they are completely recyclable. Sulfuric acid is safely neutralizable, and the lead and polypropylene case can be used in other batteries.

  • They are almost maintenance-free thanks to simple design.

Cons

  • They are too heavy and bulky for a given capacity.

  • The materials, if not recycled properly, could be hazardous to the environment.

  • They have a relatively short lifespan.

  • Spillable lead acid batteries are classified as dangerous goods. This is because of the risk of fire if shorted.

Lithium-Ion Batteries

Pros

  • They have a higher energy density. 

  • The batteries can hold electricity for a long period due to a low self-discharge rate.

  • They cause nearly no harm to the environment.

Cons

  • A protective circuit is necessary to protect the cells from complete discharge or overcharge in extreme temperatures and current surges.

  • Most lithium-ion batteries come out with a special charger.

  • They are costly compared with lead-acid batteries.

  • They cannot be transported by air according to safety regulations.
