Frequently Asked Questions
What are the available payment methods and price terms?
We accept payments through T/T, Western Union, and PayPal. Our standard price terms include FOB Shenzhen port, CFR, and CIF. Please note that customers are responsible for any local taxes or bank charges.
What is the estimated delivery time for an order?
Typically, products are shipped within 30-35 days after receiving the bank receipt. Tracking numbers and product photos will be sent via email once the shipment is arranged.
How should the batteries be stored safely?
Batteries should be stored in a cool, dry place away from heat sources and direct sunlight. Avoid storing them in spaces where acid gas may be present. If stored for long periods, a freshening charge is required every six months.
What maintenance is required for these Gel batteries?
Regular checks are recommended to ensure optimal performance. Avoid short circuits and do not charge in a sealed container. If the battery jar is broken or electrolyte leaks, clean it with a cotton cloth; avoid using organic solutions like petrol.
What is the self-discharge rate of the OPG series?
OPG series batteries can be stored for up to 6 months at 25°C (77°F). For higher storage temperatures, the freshening charge interval will be shorter due to increased self-discharge rates.
Are there any specific safety precautions?
Never put batteries in a fire as they may explode. Always use protection when handling leaked electrolyte. If your skin touches the electrolyte, wash it immediately. Batteries should be replaced if they are damaged or if the capacity is significantly reduced after one year of use.
