Three myths about household batteries debunked

Have you spent half your life buying batteries? But that doesn’t mean you know everything there is to know about batteries. Your ignorance can cost you money and waste your time. It’s time to debunk myths about batteries!

Myth number one: Disposable alkaline batteries cannot be recharged.

This may have once been a fact, but while science is advancing, battery manufacturers are in no hurry to inform consumers about it.

The pages of most alkaline batteries clearly state that they should not be recharged; the warnings are quite menacing. “Batteries can explode,” they say, but are they? Apparently not.

Test subjects willing to risk their lives recharging batteries found that they weren’t even risking their eyebrows like the scientist in the comic books, let alone their lives. Even when using short pulses of charge from a high-voltage car battery!

However, the testers noted that the batteries got hot when recharged, but the worst was a battery that gradually – and without drama – cracked on one side and leaked a very small amount of acid. It wasn’t exactly the fireworks that battery users were warned about. Visit also: Sprinter Battery price in Pakistan

Using a car battery to charge alkaline batteries not recommended for anyone in their right mind, but there are alternatives. You definitely shouldn’t use a standard charger – they can’t tell when an alkaline battery is charged, which can lead to the aforementioned overheating problem – but there are devices specifically designed to charge alkaline batteries. Some of these devices can also charge Ni-Mh and Ni-Cd batteries.

Strictly speaking, what happens to alkaline batteries is “recovery,” not “charging,” so low-energy batteries can be charged up to 90%. Nevertheless, it is possible to use chemicals from a battery ten or more times before it has to be disposed of, which saves both money and the environment.

Nevertheless, caution is advise: All batteries can have undetect malfunctions during charging that can destroy them and damage the charger or the environment. Some chargers indicate when a battery is low, but it’s a good idea to purchase a separate tester to check the condition of all the batteries you intend to charge. This is important for alkaline batteries because the more often you charge a battery, the longer it will live. But this also recommended for all other batteries. Because even the highest quality ones can defective.

If you have doubts about the quality of the batteries you use, avoid using recycled alkaline batteries in your most valuable devices.

Myth two: Battery “memory” is the real problem with rechargeable batteries

The concept of battery memory is not wrong, but it does not apply to all rechargeable batteries, and it is a problem that is slowly becoming a thing of the past.

But first of all, what is a “rechargeable battery”? Anyone who owns a rechargeable device may have noticed that battery life decreases with age. You may have your own theory as to why this happens, but when it comes to nickel-cadmium batteries, the short answer is “crystal formation.”

In nickel-cadmium batteries, crystals form inside the battery as it ages. The larger the crystals become, the harder it is for the charge to pass through them. Eventually, whole sections of the battery become inaccessible for both use and charging. Not fully discharging the battery before charging has cited as one of the main causes of this problem.

Fortunately, the problem is not fatal: if the battery is fully discharge before charging. The problem is usually solve. In fact, many chargers now do full discharge. Manufacturers are also constantly improving their batteries to get around this problem.

Lithium-ion and nickel-metal hydride batteries, the preferred power sources for devices such as cameras and cell phones, perform differently. These types of batteries don’t have this problem, so they don’t need to discharged before charged.

Lithium-ion batteries last longer if you charge them little and often. Letting them discharge before charging may shorten their life. For cameras, a discharged battery in the middle of shooting can cause the camera to stop working.

Do not confuse lithium-ion batteries with lithium batteries, which sold in household sizes. Lithium-ion batteries are the square blocks that come with cell phones and some cameras, while lithium batteries are durable but non-rechargeable batteries that sold for high-powered devices such as cameras.

Myth three: Expensive is better

Manufacturers of well-known brands would certainly like you to believe that their “quality” batteries are far superior to the generic or “own-brand” batteries available on the market. And there’s nothing stopping you from getting what you pay for.

However, there are plenty of unbiased reviews online that show that cheap batteries can certainly work well. Rechargeable nickel-metal hydride batteries from 7dayshop consistently get good reviews and very favorable comparisons to the big name brands. The internet is your friend when you need to learn the truth about cheap and supposedly high-quality batteries.

To make the right choice for your device, it’s important to know the differences between the different types of batteries and how they affect your needs. Lithium and alkaline batteries have high voltages (1.5 and 1.75, respectively), while Ni-Cd and Ni-MH batteries have lower voltages (1.2), making them unsuitable for many devices that require four or more batteries.

Unlike nickel-metal hydride batteries, which maintain a relatively constant charge until the end of their life. Alkaline batteries constantly lose voltage when their energy is deplete. If your device equipped with a power consumption monitor, your choice may make a difference.

And if you want to make the most eco-friendly choice, you should know that while lithium batteries have an incredibly long life. They cannot recharged and are especially toxic, as are rechargeable nickel-cadmium batteries.

If you’re using a camera that uses a lot of power? Nickel-cadmium batteries drain quickly, making them a problem for devices that use a lot of power. In fact, both nickel-metal hydride and nickel-cadmium batteries self-discharge within a few months: important knowledge if you’re installing low-power equipment.

There are many different types of batteries. So before you buy a regular pack at the supermarket, think about your needs, your assumptions, and your lifestyle. It can save you time and money.
