FAQ:
Φ Q1. Why battery has different capacity at different hour rate?
A: The capacity of a battery, in Ahs, is a dynamic number that is dependent on the discharge current. For example, a battery that is discharged at 10A will give you more capacity than a battery that is discharged at 100A. With the 20-hr rate, the battery is able to deliver more Ahs than with the 2-hr rate because the 20-hr rate uses a lower discharge current than the 2-hr rate.
Φ Q2. What is the shelf life of VRLA battery and how to maintain the battery?
A: The limiting factor of battery's shelf life is the rate of self-discharge which itself is temperature dependent. VRLA batteries will self-discharge less than 3% per month at 77° F (25° C). VRLA batteries should not be stored for more than 6 months at 77° F (25° C) without recharged. If in hot temperature, recharge it every 3 month. When batteries are taken out of long storage, it is recommended to recharge before use.
Φ Q3. Are you a battery manufacturer, and do you produce the plate by yourself ?
A: Yes, we are a professional battery manufacture in Guangdong Province, China. And we produce plates by ourselves.
Φ Q4. What certificate your company have?
A: ISO 9001, ISO 14001, OHSAS 18001, CE, UL, IEC 61427 test report, Patent for gel technology and other Chinese honor.
Φ Q5. How does your factory control the quality for solar energy storage system?
A: We Adopt ISO 9001 quality system to control the quality. We have Incoming Quality Control (IQC) department to test and confirm raw material meets high quality producing requirements, Production Quality Control (PQC) department contains The first Inspection, In-process quality control, acceptance inspection and full inspection, Outgoing Quality Control (OQC) department confirm no defective batteries come out from the factory.
