These are the most common and are perfect for everyday use. They're found in remotes, toys, and countless other devices. Alkaline batteries are disposable, so once they run out of juice, it's time to recycle.

Rechargeable batteries
If you're tired of constantly buying disposable batteries, rechargeables are the way to go. They're eco-friendly and cost-effective in the long run. Popular options include nickel-metal hydride (NiMH) and lithium-ion rechargeable batteries.
