More difficulty

Easy

Remains stable with different output 

Voltage fluctuation based on output 

1500 ~ 2000 cycles  (Eqivalent of around 5 years life)

150~200 times (Life is estimated 1 year)

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)

Capable of using 1C~3C charging rate (Charge to full capacity can be finished within 20 minutes)

Maximum charging rate is 0.2C (It needs at least 6 hours to fully charge the battery)

Outstanding

Acceptable

1/2 of weight to lead acid battery

comparatively heavier weight

Any direction

Upright position is necessary

Mild warm, no explosion and firing

Dangerous of acid leakage

Conforms to RoHs standard

Violet RoHs standard;Lead and sulphate acid are pollutant

No recycle required

Needs special recycle, after treatment utility
