Q: How does an ambient temperature
influence battery performance?
A: Under low temperature the battery discharge rate will
obviously reduce. At -20 °C charge speed will greatly slow down as
electrolyte is at its freezing point. Generally charge efficiency is in
direct proportion to temperature rising. But the battery materials will
be damaged when the temperature rises to 45 °C or higher. That leads
to a great shortening of the battery service life.
Q: How long can a rechargeable lithium
battery be stored?
A: Battery has a self-discharge ability during store for
its electrochemistry construction. Every month a battery self-discharge
rate is various depending on the battery design, environment and etc.
However, it will leads to an increase of the battery's internal resistance
because of the taking place of various processes during the storage. It
therefore leads to a reduction in load capability.
Q: What are the reasons for short battery
A: • Over
charged or over discharged happened which destroyed the battery.
• Charger or charge circuit does not match
to battery system.
• Battery systems are not consistent with
Q: Why are batteries with short discharge time?
A: • Battery is not fully charged.
big discharge current.
• Low ambient
Q: What do possibly results in battery unchargeable?
A: • Charger is failure to output current.
• Wrong battery
connection, or abnormity inner parts or circuit protector.
• There are 0V
• External factors
such as low temperature lead to extremely low charge rate.
Q: Why do cells or battery packs can not discharge?
A: • Self-discharge in storage.
• Battery is not
low ambient temperature and low discharge efficiency.
Q: Why does 0V or low voltage happen?
A: • Batteries are external short-circuited or overcharged,
• Internal or
slight short circuit for continues overcharging at high rate current.
