4. Deep cycle lithium battery 12V 9Ah advantage
- Output with high efficiency: Standard discharge current is 0.3C-1C,
pulse discharge current is 3.5C for 3 seconds.
- Good performance under wide temperature -20-60℃. The battery
structure is safe and good.
- 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.
- Long cycle life time, the discharge capacity is still over 80%
after 2000 cycle times of single cell(100%DOD).
- It can fast charging. It could be charged to 80% within 20 minutes
and charged full with 2-3h.
- Low self-discharge. Less than 3% per month.
- No pollution during manufacture and usage.
