A constant current/constant voltage (CC/CV) charge type with simple bulk, absorption, and float stages is required for lithium batteries. Many lead acid chargers have desulphation and equalisation stages that send high voltage pulses of 15.3–15.8V into the battery. This can cause corrosion damage to the lead plates inside a lithium battery.
Most modern lithium batteries are now protected by being wired in parallel with another cell or cells in the event of one going bad. They will then use its or their capacity more evenly so as not to damage itself or others. These packs must still be charged with care though; never leave them unattended while charging or they may explode.
Lithium-ion batteries should only be charged to 100% capacity or less. Any more than this and you run the risk of damaging the battery.
When charging lithium-ion batteries from a regular power supply, it is important to use a charger designed specifically for these batteries. Some cheap chargers that look like they would work with lithium-ion batteries may actually damage them. We recommend PowerLogic's lithium-ion specific chargers.
Lead acid is more durable than lithium. A lead-acid battery may be charged using a lithium charger without any problems. However, lead acid batteries can only be fully discharged down to about 95% capacity. Above that level, they will self-discharge over time.
Lithium batteries are less durable than lead acid. They should not be immersed in water or exposed to moisture or heat. If you immerse a lithium battery in water, it will eventually fail. The same goes for exposure to humidity or heat. These conditions can cause the battery's electrolyte to lose its fluidity and produce small bubbles that prevent the battery from delivering current. Over time, this can lead to complete battery failure.
Lithium batteries are also more expensive than lead acid batteries. This is because there is no way to reuse lithium batteries and therefore they must be disposed of properly. Old lithium batteries should never be thrown away with household trash. Disposing of them in an environmentally friendly way is important because they contain high levels of toxic material that could leach into landfill soil or be released into the air when burned.
The best alternative to a lead acid or lithium battery is to use energy storage devices that do not suffer from any of these problems, such as a capacitor or dry cell.
There are two varieties of lithium rechargeable batteries: lithium ion AAA batteries with an output voltage of 3.6–3.7 volts (or 3.2–3.7 volts) and a maximum charging voltage of 4.2 volts, and lithium ion AA batteries with an output voltage of 3.6–3.7 volts (or 3.2–3.7 volts). Li-ion means they can be charged from any direction which is different to most other types of battery. This means you can charge them while they're still in your laptop or phone if there's enough power available. They also have higher energy outputs than other types of battery.
Lithium is the lightest metal; it's used in small amounts in many products because of its advantages over other metals for use in batteries. It's very stable at room temperature, and doesn't react with air or water. However, like any other metal, it is possible to create batteries using it as a negative electrode (anode), such as the lithium iron phosphate battery developed by Sony in 1991. These batteries could handle up to 100 cycles before failing.
The earliest batteries were made from acid sources such as sulfuric or nitric. These can still be found in ancient devices such as firecrackers. But these must be disposed of properly or else they will cause pollution problems. From then on, people started looking for alternatives, and in 1859 German scientist Carl von Helmholtz invented the first electric battery, which used a salt solution instead.
Cells with a High Voltage Normal voltage lithium-ion polymer (LiPo) battery cells are completely charged at 4.2V, however lithium high-voltage (LiHv) cells allow the battery charge to achieve a higher cut-off charging voltage of 4.35V. 4.45V or 4.4V is typical for nickel metal hydride (NiMH) batteries.
Lithium-ion batteries can get very hot during use, so handle them carefully and wear protective clothing when possible. They also should be used in their recommended location on the vehicle, not inside any other component, such as the trunk or cargo area. Never leave batteries unattended while it is charging. If the battery detects a low state of charge, it will shut off to prevent damage to itself or your equipment.
Batteries contain chemicals that can leak into the environment if not disposed of properly. When discarded in landfill sites they contribute to greenhouse gas emissions and groundwater contamination.
The best way to protect the environment is by using energy efficient devices where possible and switching off appliances when they are not in use. Disposable batteries should be placed in recycling bins rather than down the toilet or thrown in the trash.
Lithium-ion batteries can store more energy and create more energy. They can also provide electricity to devices and gadgets over extended periods of time. The biggest disadvantage of lithium-ion batteries is that they are more expensive in the beginning. Lead acid batteries are less costly and require little maintenance. However, lead acid batteries have a lower maximum capacity than lithium-ion batteries.
Lithium-ion batteries are used in many products from cell phones to laptops. They are also found under the hoods of some cars as an alternative fuel source.
Lithium is the lightest metal and has the highest electrical conductivity of any metal. It also has the lowest density (1.8 g/cm3). These properties make it useful in creating small yet powerful batteries. Lithium does not react with water or most other chemicals so it cannot be damaged by exposure to heat or acids. However, it can become toxic if it gets into your body through cuts or bruises. If you come into contact with lithium, wash your skin immediately with soap and water and call your doctor.
The best known use for lithium batteries is their ability to deliver high currents for long periods of time. This makes them ideal for powering appliances that need large amounts of power but not much weight (such as lights).
Lithium batteries are more efficient at storing and producing energy than other battery types including NiCd and NaI.
