Recommendations needed for recycling batteries in Mexico

Hi everyone,

I am using a lot (~1500)  lithium AA batteries for my research based in Belize, but I haven't found any way to recycle these batteries either in Belize or in Guatemala. I think my best option is to ship these batteries to Mexico - does anyone have experience of battery recycling in Mexico or in Central America? I haven't yet located a facility that I can ship these batteries to.

Any ideas or advice would be greatly appreciated!
