GB SERIES SEALED FREE MAINTENANCE VRLA AGM BATTERY
Voltage: 12V
Capacity: 12V15Ah~12V250Ah
Designed floating service life: 8-10 years @ 25 °C/77 °F.

Summary for Solar agm battery

CSBattery GB series lead acid batteries are designed to have a large amount of stored current discharged between charging sessions, with very heavy non-porous battery plates to withstand repeated major discharging and charging cycle. The CSBattery VRLA AGM battery uses a different chemistry for the plates active paste material, and a slightly stronger electrolyte than normal battery electrolyte, thus the GB range features 30% higher cyclic life with 10 years of float life when compared to the other standard Duration range. 

Features and Advantages for sealed free maintenance lead acid battery

• 30% more cyclic life through innovation at the PAM additives
• Long life expectancy of 10 years in floating condition
• Thick flat plate with high Tin low Calcium alloy
• Wide operating temperature range from -20 °C to 50°C

CSBattery FAQ
---------------------------------------------------
                Ø Q1. Can your battery be delivered by sea and air?
                A: Yes, our batteries can be delivered both by sea and by air. We have MSDS, test report for safe transport as non-dangerous products.
                Ø Q2. Can I put my logo on the battery?
                A: Yes, you can print your logo on our batteries when you order reach 20ft container quantity. If not, price will be negotiated.
                Ø Q3. Can I fast charge my battery?
                A: Fast charging is not recommended as ifs harmful for the battery.
                ØQ4. Can I do a partial replacement of my batteries?
                A: Partial battery replacement of lead acid battery banks is not recommended.
                Ø Q5. How about your delivery time usually?
                A: About 7 days for stock products, around 20 days for half container products, 30 days for 20ft full container products.
                Ø Q6. 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.
                Ø Q7. 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.
                Ø Q8.What is your warranty time for VRLA battery ?
                A: It depends on battery capacity, depth of discharge, and battery usage. Please kindly contact us for accurate information based on detailed requirements.
                Ø Q9. 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.
                Ø Q10. 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.
                Ø Q11. How does your factory control the quality?
                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.
