Battery

Batteries have long been used to generate and store electricity, but today's mobile world is almost unimaginable without batteries, accumulators and power banks. All three types of energy cell are used in different devices and appliances. Some are used in cars, boats or small aircraft, but some are used to power smaller appliances. And power banks help charge laptops and mobile phones on the go.

Batteries are no longer just used to power up vehicles

As technology becomes more modern and advanced, the more batteries we have, the longer we can power our devices, appliances and equipment. After all, manufacturers are constantly improving them. So-called AGM car batteries are energy sources that are used as starting batteries for cars. AGM stands for Absorbent Glass Mat. This is because the batteries are covered with a special glass mat that binds the acid in the battery, making it leak-proof and durable.

The best AGM batteries have a lifespan three times longer than conventional versions. In fact, nowadays, batteries are not only used to start various engines, but also to power various equipment on a daily basis. Examples are gel batteries. Thanks to the closed system of this type of battery, the gel inside does not leak and its lifetime and safe use are outstanding. Today, lithium batteries are the most common type. They have the advantage of being liquid-free and do not need to be maintained with water, compared to sealed lead-acid batteries. In addition, there are versions that can be recharged. These types of energy cells can be charged and discharged in a short time without any loss of power, making them particularly suitable for powering cars with start-stop systems.

When do we need which battery?

There are many batteries to choose from these days. These mini batteries store the energy they contain in different forms. But today you can also buy rechargeable batteries. Rechargeable batteries offer significant long-term advantages over their conventional counterparts. In the long term, they offer a more cost-effective solution, but they also protect the environment. But let's also look at what kind of batteries we can choose from. There are, for example, AA pencil batteries and AAA micro pencil batteries, 9V batteries, flat batteries, goliath batteries, or a wide range of button batteries.

Each one is suitable for a different device. For example, the button battery cannot be used in TV remote controls because it gets lost in them. But the reverse is also true. A pencil battery is wider than a smartwatch, so we don't need this mini battery to power it. But it's not just the size that determines which battery you choose, it's also the power required by the device or appliance. Wall clocks or remote controls need medium power.

In this case, you can choose nickel cadmium batteries. Cameras, on the other hand, operate at higher power levels, so lithium batteries provide them with long-lasting power. But some devices simply don't need high voltage, and putting this type of battery in them could even damage them. So make sure you read the instructions for your appliances and only then choose the batteries.

Why is a power bank a good choice?

We travel a lot, to work, to business meetings, on holiday and on short trips at the weekends. We are almost always away from an electrical outlet. But when we're not driving, we're on the phone, using our tablets or laptops, which have a dangerously low battery charge. This is where a power bank comes in handy. Which is nothing more than a battery that has already been charged and acts as an additional power supply. But when to choose a power bank?

Choosing the right power bank depends on a number of factors, including the capacity of the power bank's battery. The larger the battery, the more often you can charge your device without having to recharge the power bank. But it is also important to check that the power bank is compatible with the device in question. However, if you travel a lot by plane, you should also be aware that some high-powered power banks cannot be taken on board. However, there are some that meet the strict requirements of aviation regulations. But let's also think about convenience and choose a power bank with useful features such as fast charging, charge level indication or surge protection. Finally, size also plays a role: the smaller the power bank, the easier it is to carry.
