What’s the Difference Between Disposable & Rechargeable Batteries?
If you count the number of devices you use that require batteries, you’ll probably come up with quite a few.
These days, we need batteries for a wide variety of items. Including cellphones, TV remotes, laptop computers, digital cameras, handheld games, etc.
Batteries are wonderful. They allow devices to work regardless of where you take them. From one room to another and outside your home. The only real problem with batteries is that they run out of “juice.”
We used to only have disposable batteries. We’d use them until they died, and then go buy new ones. Today we have a choice between disposable and rechargeable batteries. Which are better?
Today I’m going to compare the two options. But first, let’s take a quick look at how batteries work.
Releasing and absorbing electrons
All batteries have negative and positive terminals. The negative terminal connects to an anode, while the positive terminal connects to a cathode.
In a battery, the anode and cathode are separated. The anode loses electrons, while the cathode absorbs electrons. And once the terminal circuit is complete, the electrical current flows.
With a disposable battery, the anode is eventually corroded, which prevents reactions. That means the battery is now dead.
With rechargeable batteries, power can be restored to them even after they are “spent.”
Pros and cons of each
What are the pros and cons of disposable and rechargeable batteries? The upfront cost of a disposable battery is definitely a plus. They are cheaper.
If you need batteries for a number of items including flashlights, smoke alarms, game controllers, thermostats, etc., you’ll spend less money on disposable batteries.
But if you’re looking to save money over time, rechargeable batteries are more cost-effective. Disposable batteries will only last so long, and then they’re useless.
A rechargeable battery can be used over and over again. Nothing lasts forever, but these batteries can be recharged hundreds of times.
Different power draws
Of course, the power draw from various devices is different. The draw from something like a flashlight or TV remote is not strong. So, a disposable battery in that type of item will probably last for a while.
But when it comes to devices that have a faster power draw, such as a digital camera or game controllers, the battery won’t last very long.
Another con for disposable batteries is that they are not environmentally friendly. Most end up in landfills.
With rechargeable batteries, you might use a dozen or so through the years, compared to the hundreds of disposable batteries you’d use.
Saving money and time
When your battery-operated devices start to get low on power, you recharge them, right? Why not do the same for your AA batteries?
Obviously you can’t do that if the batteries are disposable. But with 4Patriots USB-Rechargeable AA Battery Kits, you can power everything you need on a single set of batteries.
Such as flashlights, radios, clocks and TV remotes. Plus toys, small electronics, digital cameras, electric razors and much more.
In fact, you’ll never need to buy traditional AA batteries again. It’s a great way to save money, not to mention saving on trips to the store when you discover you’re out of AA’s.
The choice is clear
You can charge these batteries up to 500 times. And you can do it with any USB port or the included USB dock.
So, you can charge them with a wall plug, with your laptop or in your car. And they only take 90 minutes to charge. The red light lets you know they’re charging and a blue light tells you they are fully juiced.
You can take this compact and portable charging device anywhere you go in its hard-shell storage case.
Rechargeable batteries are your clear choice over disposable batteries.
And nothing provides better backup power protection than 4Patriots USB-Rechargeable Battery Kits.
