Batteries are found in many everyday devices: in the television remote control, in the air conditioning remote control, in the Bluetooth keyboard, in the wireless mouse…
Sometimes we resort to conventional batteries (also called primary batteries) because they are cheaper than secondary or rechargeable batteries , which also require a battery charger. This initial financial outlay canadian cto cio email list is what often makes users prefer conventional batteries. In addition, rechargeable batteries have to be charged before their first use. This discourages potential buyers, who need the batteries for immediate use. Now there are new low self-discharge batteries that allow them to come charged to 70% of their capacity. Problem solved!
Knowing that you are going to use them for many years, you can now make the decision being much more conscious of your purchase.
For starters, rechargeable batteries can last up to 1,000 times longer than conventional batteries. That's a lot of lifespan! It should be the main reason to opt for this type of battery. This means that they are more environmentally friendly, since only one battery will have to be produced and you will be responsible for recharging it yourself, saving the planet from that disposable waste.
Nowadays, the terms battery and cell are used almost interchangeably, but technically they are considered batteries when they undergo an irreversible process and cannot be recharged, and they are considered batteries when they recover their charge if they are supplied with electricity. But commonly, we talk about alkaline batteries and rechargeable batteries.

Types of batteries
Batteries work thanks to electrically reversible electrochemical reactions, that is, their materials are depleted when the reaction runs in one direction, and they are recharged (if possible) when electric current enters in the opposite direction.
In terms of shape, the most popular are rectangular prism, cylindrical and button cells.
Currently there are many types of batteries, we will summarize the main ones:
Alkaline batteries: Also called Malloryson type, they are usually identified by having an "L" on the container. They have more capacity than other types of non-rechargeable batteries, providing between three and five times more operating time, although it depends on the power consumed by the device to which they are connected.
These are assigned different letters: AAA, AA, C, D... And they indicate the size of the battery and the power of these, which must be different depending on the device for which you need them.
