Tips for choosing and using batteries

• Always check the expiration date before purchasing batteries, as they can lose power over time even if unopened.

• Purchase high-quality brands that are known for longer-lasting batteries.

• Manufacturers say don't mix different types or brands of batteries in the same device as it can affect performance and cause damage.

• Use batteries regularly to prevent them from losing their charge completely. 

• Remove batteries from devices when not in use for long periods of time.

FAQs about battery life

Q: How long do batteries typically last?

A: The lifespan of a battery can vary depending on its type, brand, and usage. Most batteries have an estimated shelf life between 5-10 years. But when in use, battery life really depends on how much you use the charged item and how much battery it requires. 

Q: Can I use rechargeable batteries in all devices?

A: It's important to check the device's manual or packaging to see if it is compatible with rechargeable batteries. Rechargeable batteries usually work best with things that use a lot of power in a short period of time. For example: your computer mouse or an electric toy car. 

Q: Do alkaline or lithium batteries last longer?

A: It depends on the specific brand and type of battery, but generally, lithium batteries have a longer lifespan and can hold their charge for longer periods of time.

Q: How should I dispose of old batteries?

A: The answer depends on which battery type. Proper disposal of batteries is important for safety and environmental reasons. Follow the Environmental Protection Agency (EPA) guidelines and your local city or state regulations. Many municipalities have local recycling facility or drop-off point specifically designated for battery disposal. Always check with your local recycling and waste management authorities as the guidelines often change. 

Q: Can batteries be left in a hot car?

A: Intense heat and batteries don't mix well. High temperatures can lead to leakage or even cause them to burst. Keep your batteries in a cool, dry place to maintain their efficiency and lifespan. If they’ve been subjected to extreme heat, discard them safely and start fresh.

While storing batteries in the freezer may seem like a way to prolong their life, it can actually damage them. The same goes for storing batteries in the refrigerator. It's best to store them at room temperature and use them regularly. Remember to always check expiration dates, choose high-quality brands, and avoid mixing different types of batteries.
