卡塔尔采购需求：12V12Ah，铅酸电池，可充电电池，密封免维护电池，深循环电池，12伏电池

I'm looking to source a specific type of rechargeable valve-regulated lead-acid battery. The battery I need should have a nominal voltage of 12V and a capacity of 6Ah, suitable for long continuous use without spillage issues. Please provide detailed information about your available models that meet these specifications, including pricing, lead times, and any applicable certifications. I'm particularly interested in understanding the battery's performance characteristics and any warranty options you might offer. Thank you!
