In Europe recycling is easyevery store that sells batteries must take them back for recycling too. That's because the process just isn't as cost-effective for the recyclers.A handful of retailers collect do collect them, though I don't know of any who collect them at all their nationwide stores.
Don't confuse AA Lithiums with Lithium-Ion battery packs (like the kind that come with laptops and many cell phones).In California, all batteries are considered hazardous materials, so they can't just be thrown in the trash.Check with your county government about collection facilities in your area.Alkalines perform poorly at subfreezing temperatures (reduced capacity), as this chart from Energizer (PDF) shows.Nickel Zinc and Lithium are better for below-freezing applications.This is nice especially given that smoke detector batteries are bothersome to replace. mail and why they can't go in your checked luggage when you fly.
And when you go through only one battery every few years, rechargeability becomes less important. It's rare for lithium batteries to explode, but they're more likely to than other kinds of batteries. Here's a story about someone who nearly lost a finger when the lithium cell in his flashlight exploded.
After that, use cotton swabs with vinegar or lemon juice.
The acid will neutralize the leaked alkaline material to prevent further corrosion. (If using one of those, wear safety glasses, so you don't flick the solution into your eyes.) Temperature.

Those Lithium-Ion packs are rechargeable, but only when they're installed in the device they're powering, or in a special charger.
