Li-ion batteries are both durable and safe for use in vehicles. And can be used in many applications.

Lithium-ion batteries have significantly higher cycle life than Lead-Acid Batteries. They have 3 times higher lifecycle rate.

Lithium-Ion batteries are about a third of the weight and half of the volume when compared to Lead Acid Batteries. Li-Ion Batteries are very compact.

They are considered as one of the most eco-friendly battery. It is totally environmentally friendly. They are compatible with solar applications and thus have a wide range of applications nowadays.

If the voltage while charging is taken care, Li-Ion Battery does not require maintenance like Lead-Acid Battery. While lead acid batteries must go through routine saturating charges lasting 14 hours or longer, Li-Ion maintains consistent power even if you only charge it partially.

Lithium-ion batteries can hold a charge for many months. It is best to store a lithium-ion battery with a partial or full charge. Occasionally, a lithium-ion battery with a very low charge is stored for a long period of time (many months) and its voltage slowly drops to below the level at which its built-in safety mechanism allows it to be charged again.

The biggest differences are that lithium batteries contain lithium metal and are not rechargeable. Lithium-ion batteries, however, do not contain lithium metal and can be recharged.
