Lithium ion Battery
Lead Acid Battery
Remains stable with different output
Voltage fluctuation based on output
500 ~700 cycles
150~300 times
Very stable and very little affection by output current
Suffer a big affection in by output current. Capacity will be much smaller than rated capacity when output current is large.
99%
50-60%
1~1.5% (Capacity remains over 80% even the battery is idled for one year)
30% (Battery capacity drops near to zero if it is unused for 3 months)
Charge to full capacity in about 6 hours
needs 8 ~ 12 hours to fully charge the battery
-20~+75
-20~+55
None
Outstanding
Acceptable
1/4 of weight to lead acid battery
comparatively heavier weight
Any direction
Upright position is necessary
Built-in safety protection function
Danger of acid leakage
Conforms to RoHs standard
Violates RoHs standard;Lead and sulphate acid are pollutants
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 to be specially recycled after treatment utility
