Lead-acid battery capacity test index

Label: Lead-acid battery capacity test indicators When testing the lead-acid battery capacity, you can refer to the following three indicators 1. Reserve capacity Reserve capacity refers to the shortest time that the lead-acid battery charging system can provide the machine to work normally, that is, when the lead-acid battery charging system fails. The battery is discharged with a fixed discharge current (the discharge current should not be too large or too small) to reach the duration of the termination voltage. 2. Cold-start current The cold-start current requires the maximum current value that can be output in a short time when the ambient temperature is minus 18 ℃. With the same capacity, the larger the current value, the better the performance. 3. 20hr discharge capacity This indicator refers to the amount of electricity that a lead-acid battery can discharge within 20 hours under a constant temperature environment of 25 ℃.
Every day of the year, there is some city or town in the world that is changing over to for top lead acid battery manufacturers.
Shenzhen Power Kingdom Co., Ltd. are dedicated to providing excellent underwriting and loss control advice up front, and to ensuring superior customer service through the life of the policy.
We are professional in manufacturing sealed lead acid battery, and always emphasize the technology and quality during the producing procedure.
We take advantage of high technology to produce products that support safer and better quality and that enhance the using experience of sealed lead acid battery.
