Three main types of rechargeable batteries are used in new technology handheld devices.Scientists have been trying to develop batteries with better technology to make them faster, stronger and lighter.In the past, the only rechargeable battery type available was lead-Acid batteries with liquid must be kept upright and ventilated.Although it is still used on cars and motorcycles, scientists have developed gelBattery, half liquid.No overflow.These are nickel batteries, most commonly used in new handheld devices.Cadmium (NiCad), nickel metal-Hydrogen ions (NiMH) and the latest lithium ion (Li-Ion) batteries.The nickel-cadmium battery is the lowest price among the three batteries because it has the least power.They are mainly used for portable phones, power tools and other handheld devices.They are more practical than leaders.Acid batteries because of their increased power and weight.They also have an advantage over alkaline batteries that are generally not rechargeable.NiCad is said to be the number one victim of the memory effect, which is actually a lazy battery effect in which the battery discharges rapidly after it is fully charged.A NiCad battery lasts only 1000 full cycles, so it needs to be replaced in the end.NiMh battery is the next podium for newer, more powerful batteries.Although NiMh batteries are similar to NiCad batteries, they do not contain toxic cadmium and are therefore considered more eco-friendly.Friendly BatteryThey also have higher capacity than NiCad and are said to not be affected by memoryAlso valid.It is very important to follow the appropriate steps for NiMH battery charging and discharging.The NiMh battery requires a smart charger to prevent the battery from overchargingcharging.It is also important that they do not run flat in portable devices, which will result in reverse charging, thus completely damaging the battery.Most devices detect a safe discharge voltage and turn it off automatically.In this case, NiMH batteries are more effective in high-drain devices such as digital cameras, while NiCad batteries are more effective in devices with faster discharge rates, such as power tools.NiMH batteries are also used in hybrid cars.Of all rechargeable battery types, the latest and most powerful ones are lithium-ion batteries.Compared with NiCad and NiMh batteries, Li-The ion battery has the highest voltage density and the lowest self-discharge rate.It's the smallest and lightest.The weight of all batteries, but all the advantages also make it more expensive.New Li-It is said that the charging speed of the ion battery is 10 times that of the NiMH or NiCad battery, and the charging speed is only very short.Li-Ions are very vulnerable to high temperatures, which can greatly shorten their lifetime.Very high temperatures can also cause Li-Ion battery to explodeDifferent types of batteries have their own advantages and disadvantages.Although some batteries provide more convenience and higher capacity, the development of batteries still faces many restrictions.Battery technology is improving every day, however, to help portable devices last longer.
