Size Comparison


Comparison with a similar capacity Sealed Acid Battery

Although this battery is rated as 24V 9Ah, theoretically  its capacity is equivalent to a 12V 18Ah lead acid battery. However, this lithium battery can be fully discharged while most lead acid battery can not be fully discharged, this battery actual output capacity  may be  close to a 12V 22Ah ~ 24Ah lead acid battery.  
Lithium-ion battery vs. Lead Acid Battery
Using Lithium-ion battery  offers many advantages over older SLA (Sealed Lead Acid) battery  because of  Lithium-ion battery's high energy density, small size, and low weight.   A typical Lithium-ion battery may only has 1/4 of weight and 1/2 of size compare to same capacity traditional  heavy bulky Sealed Lead Acid batter. This battery weight is less than 4 pounds. A same capacity Sealed Lead Acid battery may weigh around 16 pounds.)

Disposition of used battery

Lithium-ion batteries are generally not considered an environmental hazard because they do not contain lithium metal. The United States government labels them as non-hazardous waste and does not oppose them being discarded together with the trash that makes up the local waste stream.

Needs special recycle, after treatment utility


Although this battery is rated as 24V 9Ah, theoretically  its capacity is equivalent to a 12V 18Ah lead acid battery. But since this lithium battery can be deeply discharged while most lead acid battery can not, this battery actual output capacity  may be  close to a 12V 22Ah ~ 24Ah battery.
