Generally, it is recommended to charge for more than 4 hours and less than 12 hours. According to the brand, battery type and all materials, please follow the instructions.
Rechargeable battery is a kind of rechargeable battery with limited charging times, which is used in conjunction with charger. The general market sells numbers 5 and 7, but there are also numbers 1. Rechargeable batteries have the advantages of economy, environmental protection and sufficient electricity, and are suitable for high-power and long-term electrical appliances (such as walkman and electric toys). ).
Types of rechargeable batteries:
Nickel-cadmium alloy
Voltage: 1.2V Service life: 500 times.
The discharge temperature is -20 ~ 60 degrees.
Charging temperature: 0 ~ 45 degrees.
Nickel-hydrogen alloy
Voltage:1.2v.
Service life: 1000 times.
The discharge temperature is-10 ~ 45℃
Charging temperature: 10 ~ 45℃
Remarks: At present, the maximum capacity of domestic No.5 battery is about 3000mAh.
Lithium-ion batteries
Voltage: 3.6V
Service life: 500 times.
The discharge temperature is -20 ~ 60 degrees.
Charging temperature: 0 ~ 45 degrees.
Remarks: the weight is 30% ~ 40% lighter than that of Ni-MH battery, and the capacity is more than 60% higher than that of Ni-MH battery. But it is not resistant to overcharge. If overcharged, it will damage the structure and cause an explosion.
Lithium polymer
Voltage: 3.7V
Service life: 500 times discharge temperature: -20 ~ 60 degrees.
Charging temperature: 0 ~ 45 degrees.
Remarks: The improved lithium battery does not have battery solution, but uses polymer electrolyte, which can be made into various shapes and is more stable than lithium battery.
lead-acid cell
Voltage: 12V
Service life: 200 ~ 300 times.
The discharge temperature is 0 ~ 45 degrees.
Charging temperature: 0 ~ 45 degrees.
Remarks: It is a general vehicle battery (composed of 6 2V batteries in series 12V). The waterless service life of the battery is as long as 10 year, but its volume and capacity are the largest.
