美国采购需求：6FM6电池，12V6Ah电池，密封铅酸电池，可充电电池，12V电池，6Ah电池

I'm looking for pricing details for a specific type of 12V rechargeable battery that serves as a replacement option for a common model. The required specifications include a capacity of around 6Ah. Could you please provide me with your best pricing options, including any bulk purchase discounts, lead times for delivery, and warranty information? Additionally, if you have any alternative suggestions that meet these requirements, I'd love to explore those as well. Thank you!
