Greening Your Battery Usage

Monday, October 12, 2009
The nice folks over at have published a list of helpful tips for using batteries in a more environmentally friendly way. While the best green tip for batteries is to recycle them (tip #2), there certainly are some other practices that can help you prolong battery life and limit their harmful effects.

Here's the list:

1. Replace One at a Time
So your device stopped working, and it takes four AA batteries. Looks like you’ve got to buy four new batteries and dispose of four as well. Actually, only one of the batteries may be dead. If you invest in a battery-tester, you can find out which batteries have no charge left and only replace those. Some batteries even come with a tester on the cell itself. If they end up needing to be tossed, check out mail-back programs for all your battery recycling needs.

2. Embrace Heavy Metal
In most circumstances, searching for a product with less hazardous materials is more eco-friendly. In the case of batteries, hazardous ingredients increase your chances of finding recycling options. Consider:
  • Car batteries contain lead and sulfuric acid and have a recycling rate around 90 percent.
  • Single-use dry cell batteries have been gutted of mercury in recent years, and it’s now much more difficult to find locations that recycle them than rechargeables (which contain cadmium).
If your batteries have elements like lead, mercury or lithium, there will be more value to a recycler that can reprocess these metals. Just make sure they are kept out of the reach of children and pets in the meantime.

3. Laptops Aren’t for Laps
You already know that batteries and heat do not get along together. Well, your computer generates a fair amount of heat internally, which is why your notebook computer comes with a fan. Using your laptop on a soft surface (such as your lap) restricts air flow and actually heats up your battery. You can also invest in a cooling pad if you want to use a notebook on soft surfaces. Keeping the battery cool will help extend its lifespan.

4. Keep Your Batteries Cool
You may have heard that putting batteries in the fridge or freezer will make them last longer. While this may be the case, you’ll have to let the batteries thaw before using them to avoid condensation in your devices. Regardless, you should avoid storing batteries in hot places, because they could leak fluid.

5. Wait for Good Reception
“Can you hear me now?” That’s good for more than just your phone manners. When your cell phone has low reception, it uses more battery power to search for stronger signals. Waiting for better reception will allow your cell phone battery to last longer.

6. Insulate Your Car Battery
Think about it: your car experiences more temperature fluctuations than anything else in your life. It deals with hot and cold driving weather, gets heated up and cooled down on every trip and ends up stored in a poorly-insulated garage for the night (if it’s lucky).

You can find insulation blankets to allow car batteries to adjust better to all kinds of temperatures. The next time you’re under the hood, check to see if your battery is insulated or have a qualified professional check for you.

7. Crank Up Your Batteries
The days of hand cranks to generate power went out with draft cards and freedom marches. Or did they? You can actually find hand-cranks to charge up all sorts of devices, such as cell phones and mp3 players. You’ll also get a little exercise. Another option is charging your gadgets with solar power. These are both forms of renewable energy so you won’t have to use non-renewable electricity to power your batteries.

8. Opt for Plugging In
Many devices will come equipped with battery compartments and an A/C power adapter, including some alarm clocks and lamps. You may be saving energy by working off batteries, but you’re also producing waste when the batteries die. Don’t forget you have to spend energy to recharge batteries as well. If you have the option, plugging in will use less resources.

I have to commend this blog for it's very precise and very informative especially for people like me who use batteries most of the time. I never knew that using a phone with a lower reception could affect the battery consumption; I must admit that even if my phone's signal is low I still keep on resending my messages. Because of this article I have learned how to conserve my battery and also help the environment by conserving energy.
