Lithium ion battery voltage remains stable with different output .
Lead Acid battery voltage fluctuation based on output.
Lithium ion battery Cycle Life: 500 ~800 times.
Lead Acid battery Cycle Life: 150~300 times.
Lithium ion battery Capacity is very
stable and very little affection by output current.
Lead Acid battery Capacity suffers a big affection in by output current. Capacity will be much smaller than rated capacity when output current is large.
Lithium ion battery Depth of Discharge (D.O.D.) can up to 99%.
Lead Acid battery Depth of Discharge is around 50-60%
Lithium ion battery Self discharge rate (per month) is 1~1.5%
(Capacity remains over 80% even the battery is idled for one year).
Lead Acid battery Self discharge rate (per month) is around 30% (Battery capacity drops near to zero if it is unused for 3 months)
Lithium ion battery can be charge
to full capacity in about 6 hours.
Lead Acid battery needs 8 ~ 12 hours to fully charge the battery.
Lithium ion battery discharge working temperature range: -20~+75 C.
Lead Acid battery discharge working temperature range: -20~+55 C.
Lithium ion battery Thermal stability: Outstanding.
Lead Acid battery Thermal stability: Acceptable.
Lithium ion battery only has 1/4 of
weight to same capacity lead acid battery.
Lead Acid battery is comparatively heavier in weight.
Lithium ion battery can be installed in any
Lead Acid battery installation: Upright position is necessary.
Lithium ion battery has Built-in safety protection function.
Lead Acid battery: Danger of acid leakage
Lithium ion battery: Conforms
to RoHs standard.
Lead Acid Battery: 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.
Lead Acid battery needs special recycling after treatment utility
