Sealed Lead Acid is widely used in power back-up or stationary devices as well as electric wheelchairs and other similar products.
Lead acid technology is more than 100 years old but continues to be widely used where size and weight are not key factors. Sealed lead acid batteries are easy to charge and give a reasonably accurate indication of their state of charge by looking at their voltage.
Sealed Lead acid batteries are available in an enormous array of sizes and shapes including single 2 volt cells.

Excell is committed to supporting and promoting responsible and ethical recycling of all products. Wet Lead Acid batteries are the most common batteries used in energy systems because of their price, local availability, and ease of recycling.
Gel Cell batteries are also lead acid but the electrolyte is in gelatin form instead of liquid. Wave of the future: An Intel employee shows of Rezence, a wireless charging technology being championed by Intel which can charge multiple devices at once and works through tables up to 2in thick. Invented as far back as 1859 by Gaston Plante, the lead-acid model is the first battery that could be recharged by running an electrical current back into it. The interesting thing about lead acid batteries is that the reaction can be reversed by passing a reverse current through it, essentially recharging the battery. Lead acid batteries are still used in cars and motorcycles today but because of the relatively low charge they hold compared to their weight, not to mention the harmful chemicals, lead acid batteries are not practical for mobile devices. Nickel-cadmium (also known as NiCd or NiCad) were the first rechargeable batteries that were used in a variety of devices from remote control cars to cordless phones and early handphones.
Invented in 1899 by Waldemar Jungner, the battery uses electrodes made of nickel and cadmium in an alkaline bath of potassium hyrdoxide.
Nickel-cadmium has a terminal voltage of about 1.2 volts and a charge cycle of around 2,000, but it came with several disadvantages.
Although it is possible to revive a NiCd battery to almost full capacity and voltage by completely discharging and recharging it several times but it was too tedious a process for most users. Lead acid batteries are still used in cars, motorcycles and uninterruptible power supplies today. Nickel-metal Hydride (NiMH) cells have largely replaced NiCd as the default battery for most electronics devices that use AA- or AAA-sized battery. Invented in 1967, NiMH use a complex alloy of various metals as well as nickel-hydroxide electrodes in an alkaline bath of potassium hydroxide.
Contrary to popular belief, NiMH batteries also suffer from memory effect though not as badly as they only have to be discharged completely once in awhile to avoid the voltage suppression effect. In 2005, Japanese electronics company Sanyo had a big breakthrough with its Eneloop battery, which is an NiMH battery with a very low discharge rate. The Eneloop (and similar batteries) achieves this by having more efficient separators which keep the two electrodes apart to slow down electrical discharge. In later batteries the company used thinner separators made of more advanced materials to increase the capacity of the battery.
Panasonic acquired Sanyo in 2009, and now Eneloop batteries are sold under the Panasonic brand name. Although research into lithium batteries began as early as 1912, the first rechargeable lithium-ion batteries were only created in 1985 and commercialised in 1991. Lithium-ion batteries use a complex mix of materials – the cathode is made up of lithium molecules trapped within other compounds, while the anode is usually graphite or a mix of carbon and other compounds. In fact, the chemistry is quite varied, with anodes, cathodes and the electrolyte solutions using a mix of lithium and other chemicals to offer different effects – more charge, more density, more stability or more resistance to overheating. The lithium polymer variety is the same but the electrolyte is a solid polymer composite with laminated electrodes and separators which allow manufacturers, especially phone makers, to create a flexible battery that can be moulded to conform to the limited interior space of a smartphone. Lithium-ion batteries’ biggest disadvantage is that they can be overcharged which can cause the lithium-ion cells to combust, often with very spectacular (if extremely dangerous) results.


In fact, lithium-ion batteries can combust so easily that even short-circuiting them by connecting the two terminals will cause them to catch fire and explode. Most manufacturers prevent this by making the terminals recessed so it’s impossible for them to short circuit accidentally. Because of the risk of overheating and possibly fire, lithium-ion battery packs are designed with terminals that are more difficult to accidentally short circuit. The constant demand for more capacity and faster charging has accelerated research into many battery types. Another possible battery technology is the Na-ion which is essentially made up of sodium-ion or salt – it can hold as much charge as lithium batteries but lasts almost twice as long as it can handle 2,000 charge cycles. There are also solid-state batteries currently being researched by scientists at MIT and Samsung, which offer 20% to 30% improvement in power density compared to lithium-ion and can be recharged thousands of times before it degrades. Beyond just battery technology, scientists are also researching more convenient ways to recharge our mobile devices. One of the technologies that is already available now but that has yet to catch on is wireless charging. There are essentially two types of wireless charging technologies, namely inductive charging and magnetic resonance charging. Both technologies use the same principle – electricity flows though a tightly coiled wire which creates an electromagnetic field that transfers voltage to a nearby object.
Magnetic resonance charging, which was demonstrated by Intel for its Rezence wireless charging technology at its annual IDF conference, works even when the charger and the device are separated by several inches, but is not as efficient as inductive charging. Currently there are two competing standards – the Qi standard which is championed by the Wireless Power Consortium, and PMA which is headed by the AirFuel Alliance (which is made up to two formerly competing wireless standards).
While everyone is hoping that the two will merge, companies like Samsung have started supporting both wireless standards. Batteries are a common part of daily life; they provide power for everything from your car to your smartphone.
Exposure to the chemicals contained in batteries can lead to health problems, even if no physical contact with the acid is made.
To avoid exposure to hazardous materials, you should always be vigilant when working with batteries. If you have young children in your house, you need to take extra precautions with batteries.
Due to the hazardous chemicals contained in batteries, throwing out old batteries with your other garbage can hurt the environment.
It’s odd to me how people think they can charge their battery in their cell phone forever.

Sealed Lead Acid is often used in power back-up or stationary devices as well as electric wheelchairs and other similar products. The battery was toxic (due to cadmium) and suffered from the infamous memory effect (or voltage suppression if you want to get technical) – if a NiCd battery is repeatedly recharged before it was fully depleted, its voltage and capacity will be reduced.
The relatively large size and dangerous chemicals used means its of limited use in handheld devices.
The company claimed that the battery could retain up to 70% to 85% of its charge even after a year. Of the two technology, inductive charging method is the more efficient one but only works at very close range, typically less than 1.5in. Although batteries are inherently safe when intact, most battery types contain harmful chemicals that can cause problems if the leaked, including damage to the device holding the battery and anyone exposed to its contents. For example, in lead-acid batteries, breathing the exposed lead from a leak can cause brain and kidney damage.
Always use a battery for its designed purpose; when forced beyond their designs, batteries are more likely to leak or vent dangerous chemicals. Small batteries, such as those found in watches and other devices, can easily be grabbed and swallowed by a child. Always keep your batteries in a cool and dry space; temperatures over 120 degrees Fahrenheit can cause batteries to overheat and swell up.

They can pose safety risks to workers in the form of fires and explosions, or health risks due to their chemical properties. This must include temporary storage of flammable liquids and consideration of likely ignition sources, such as welding, grinding and other hot work, which could cause flammable vapours to ignite. Gases released when batteries are charging - hydrogen (very flammable and easily ignited) and oxygen (supports combustion) - can result in an explosion. They can also be stored in any position and since there are no dangerous fumes, they can be placed in any part of the house. Understanding the dangers of battery acid can help you make better decisions when handling and storing batteries. Battery-powered toys are another source of small batteries, and children are likely to stumble across these batteries by accident.
Keeping batteries in a closet or drawer, as long as it remains room temperature, should be sufficient to prevent storage damage. Some cities hold regular hazardous disposal events to collect old batteries and electronics.
Some parents choose to avoid the danger of small batteries by not buying battery-powered toys until their children are older. If the battery is rechargeable, research the battery to determine how long it should be charged to avoid any overheating issues. Leaving a battery in a device that you will be storing for a long time can drain the battery and may even lead to some unpleasant surprises, such as battery leaks, when you retrieve the device from storage. Nickel-cadmium batteries also contain harmful chemicals and can cause serious health problems if ingested such as damage to internal organs. Small batteries can also be ingested accidentally by small children; once inside the body, these batteries can begin leaking hazardous chemicals directly into the stomach. However, nickel-metal-hydride and lithium-ion batteries are generally considered safe and contain little or no hazardous materials.
