4. Deep cycle lithium battery 12V 9Ah advantage

  1. Output with high efficiency: Standard discharge current is 0.3C-1C, pulse discharge current is 3.5C for 3 seconds.
  2. Good performance under wide temperature -20-60℃. The battery structure is safe and good.
  3. Good safety performance: When the pressure inside the battery is too large, the one-way safety valve will release gas and heat to make sure battery perform well. When the internal pressure reaches a certain level, the valve will be open immediately which can protect the battery from burning and explosion.
  4. Long cycle life time, the discharge capacity is still over 80% after 2000 cycle times of single cell(100%DOD).
  5. It can fast charging. It could be charged to 80% within 20 minutes and charged full with 2-3h.
  6. Low self-discharge. Less than 3% per month.
  7. No pollution during manufacture and usage.

5. Application

Electric propelling applications: engine starting battery; Slow Speed Car; intellectual robots; electric bicycle/motorcycle/scooter; golf trolley/carts/ sightseeing car; power tools.

Energy storage: solar and wind power system; city on/off grid; community and family, RV Caravan, Marine yachts.

Back-up system and UPS: telecom base, CATV-system, computer server center, medical instrument, military equipment.

Other applications: security and electronics; mobile POS, mining light/torch/LED light/emergency light.
