The history of battery chargers is long but interesting. Chargers and rechargeable batteries date back to the 1800’s. The concepts and designs have taken on new meaning in the era of portable electronics. With new technology there is charger for almost everything imaginable. The devices are widely used, and their progression over time is huge.
The first battery charger was for the car. The idea came from Gaston Plante, a French physicist that invented the lead acid cell battery in 1859. Though, it was years later that the idea became what it is today, he was the pioneer of the concepts. It was Waldemar Jungner that discovered the Nickel-Cadmium battery in 1899. The Swedish scientist developed this product and it was on the market by 1906. These men of science had ideas before their times. Imagine what they would think of today progress of their once simple ideas.
Chargers for lithium-Ion batteries are almost a necessity in society today. Being used in everything from mobile phones, to laptops, and many other portable devices, they are a must for most. They were introduced in 1991 by Sony. The twenty year phenomenon in the making was originally theorized in the 1970s. Nickel-Metal Hydride was created in the 1980s. This battery comes in all sizes and is probably the most common household battery used today.
Battery charging devices are a common item to own. They come into play with the invention of rechargeable batteries. The idea behind it all was not only to save money but to save time. The average person can save hundreds of dollars per year by using rechargeable batteries with a battery charger. That same person can also save a great deal of time. The more modern designs were also intended to help save the environment by reducing waste and eliminating unnecessary uses of extra energy. The researchers of the pasts would be proud of where the designs have led.
The thought of not having a battery charger for practically everything you own has probably never crossed your mind, but let it for a moment. If you did not have a mobile phone charger or if you weren’t able to recharge those AA batteries for the digital camera what would you do? The concepts may not all have been intended for what they have become, but the transition over time is surely remarkable. Chargers and rechargeable batteries in yesterday’s world are the building blocks for today’s models. So much has developed in the last hundred years in this science. When one looks back at the past and sees what has become, one can help but to think of the future and wonder what will be.

Stand Alone 240v Mains Smoke Alarm Vs Battery Smoke Alarms
As the name suggests, a smoke detector is the piece of equipment placed in homes or buildings to detect smoke caused by a fire. In a commercial or industrial setting, smoke detectors issue a signal to a centralised fire alarm system. Stand alone smoke detectors, also known as smoke alarms, for domestic or small commercial settings send out a locally audible or visual alarm from the detector itself. Whichever process they use, the fact remains that “smoke alarms are life savers”. These devices help you to avoid any mishap or disaster due to sudden break out of fire. They send out the signal at the slightess hint of smoke detected in the air allowing us to take timely preventive measures. There have been many instances in the past where some serious damage to life and property could have been avoided if smoke alarms had been fitted.
Most smoke alarms can easily detect the smoke produced by flaming fire, smouldering fire, and even a slow burning fire. If you are planning to buy a smoke alarm for your house, you have three options: mains smoke alarm, mains smoke alarm with battery back up or battery only smoke alarm. The battery smoke alarm is powered by a battery, whilst a mains smoke alarm is powered by the mains electricity.
Battery powered smoke alarms are simple and easy to install. It is still desirable to have battery back up in a mains smoke alarm to allow the smoke alarm to carry on working even in the even of a power cut or electricity failure. In a standard battery smoke alarm, the battery would need to be replaced every 12 months. However, you could opt for the ones that are fitted with 10 and 15 year batteries to avoid the hassle of replacing the battery every year.
Mains smoke alarms need to be installed by a qualified electrician. Now, most mains smoke alarms come with a battery backup to ensure continual functionality regardless of the situation in hand. Both battery and mains smoke alarms offer additional benefits as well. For instance, these devices also feature emergency lights and silence buttons, for use where false alarms can be a nuisance especially when you are cooking. Some are also interlinkable, which means any smoke detected at one point can raise alarm at all other points as well.
Firex is one of the leading brands offering a wide range of both battery and mains smoke alarms. You may choose to buy Firex 230/240V, a mains interlinkable smoke alarm for your house. It comes with an Alkaline battery backup which provides a standby supply for up to 4 years. Its L models come with a Lithium battery or Lithium rechargeable batteries providing a backup of 10 years.
