Battery Type
|
Lithium ion Battery
|
Lead Acid Battery
|
Voltage fluctuation in working
|
Remains stable with different output
|
Voltage fluctuation based on output
|
Cycle life
(Residual capacity over 5%)
|
500 ~1000 cycles
|
150~300 times
|
Capacity
|
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.
|
Depth Of Discharge (D.O.D.)
|
99%
|
50% ~ 60%
|
Self discharge rate (per month)
|
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)
|
Fast charge capability
|
Charge to full capacity in about 6 hours
|
8 ~ 12 hours to fully charge the battery
|
Discharge working temperature ℃
|
-20~+60
|
-20~+55
|
Memory effective
|
None
|
None
|
Thermal stability
|
Outstanding
|
Acceptable
|
Weight (Compare to the same capacity)
|
1/4 of the weight compared to lead acid battery
|
comparatively heavier weight
|
Installation
|
Any direction
|
Upright position is necessary
|
Safety
|
Built-in safety protection function
|
Danger of acid leakage
|
Environmental conform-ability
|
Conforms to RoHs standard
|
Violates RoHs standard;Lead and sulphate acid are pollutant
|
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 recycling after treatment utility
