Best Lithium Rechargeable Batteries-Type and Charging
Lithium rechargeable batteries are electrical batteries that can be discharged, charged, and recharged several times. It is opposed to primary or disposable batteries that are equipped with a full charge and disposed of after usage. It consists of one or many electrochemical cells. Rechargeable batteries are referred to as accumulators seeing that they accumulate and keep power by changeable electrochemical reaction. They are manufactured in various sizes, shapes, megawatt systems to button cells. The systems are connected in order to stabilize the distribution of the electrical network. In addition, there are different brands of lithium rechargeable batteries with distinct features. Also, the batteries should be charged properly.
What are the best lithium rechargeable batteries?
Selecting the best lithium rechargeable batteries will save a lot of money by recharging them while drained. They have several cycles of recharging, which can last for many years before you buy them. Here is the list of best rechargeable lithium batteries.
AA and AAA batteries
AA and AAA rechargeable batteries have a charge capacity up to 2000mAh. Also, it can be recharged to 1000 times. They will help you to save money by charging them regularly. The batteries have four times capacity over nickel-metal hydride and nickel-cadmium batteries.
Li-ion battery is an advanced battery that uses lithium ions to act as the main component of electrochemistry.it has been ranked as a battery with the highest energy density compared to other rechargeable technologies. For this reason, they can give high amounts of currently used to power great applications. Moreover, they do not have memory effect when frequently discharged and charged partially. This is a great advantage than Ni-MH and Ni-Cd that experience memory effect.
These batteries have a lower self-discharge rate that is around 1.5% to 2%. Additionally, lithium is a non-toxic metal; hence it is safe for our mother nature. Their countless advantages will make you consider them over other batteries.
Li-poly uses polymer electrolyte and not a liquid electrolyte. These batteries have the ability to give great specific energy over lithium types of batteries. This advantage makes them be used in high powered applications. Li-po batteries give manufacturers and users exceeding advantages. They are easily molded into desired shapes. Therefore, the requirements of computers and mobile devices can be met. The batteries are useful in electric cars, trains, and aircraft controlled by radios. Another benefit is that they only discharge at 5% per month. These listed advantages make lithium polymer to be ranked among the best lithium rechargeable batteries.
What type of rechargeable battery lasts the longest?
Eneloop Pro, AA battery
Eneloop batteries are the type of AA rechargeable batteries released in 2005. Generally, Eneloops have the ability to retain longest than other rechargeable and low self-discharge batteries. These batteries can hold a charge of 85% for a single year and lower to 75% for three years.
Sanyo developed a new Eneloop version called “Eneloop pro” in japan or referred to “Sanyo XX Battery Powered by Eneloop” in the United States and Europe. Eneloop Pro has a battery capacity of 2500mAh, and this exceeds by 500mAh over the regular Eneloop.
Tests have shown that Eneloop pro can retain 2035mAh after storing for seven-week. This is higher than Ni-MH battery; it makes Eneloop to be the longest rechargeable AA battery. Another battery coming close to Eneloop pro is "Energizer Recharge" it retains 1859mAh after keeping for seven weeks.
You should be extra careful when purchasing Eneloop belonging to AA rechargeable battery. They look similar but have clear differences. Nowadays, some manufacturers produce fake Eneloop pro battery since it is a competitive battery in the market. Genuine one includes Panasonic Eneloop pro that has a label of 2550mAh as well as pre-charged on the packing. Fake ones are labeled 2500mAh, and the packing is pre-charged rechargeable.
How do you charge the lithium rechargeable batteries properly?
You can prolong power by following the correct procedure for charging. Below are simple guidelines to consider
Disconnect the device in order to allow current to reduce during saturation. The parasitic load can affect the charger.
Avoiding charging at freezing temperature, charge at normal temperature.
Lithium-based batteries do not need a complete charge. A partial charge will be better.
Some chargers do not give a full topping charge; hence the battery might not be completely charged. Therefore, a 100% charge cannot be true.
Discontinue using battery or charger in case the battery becomes extremely warm.
Put 40 to 50% charge on an empty battery prior to storing.
Lithium-based batteries normally charge up to 4.2 volts or 4.3 volts for high capacity ones. You can boost voltage in order to increase capacity. However, going beyond its recommendation will stress the battery and cause problems. The inbuilt protection circuit does not allow a maximum set of voltage.
Lithium batteries are completely charged when current lowers to a particular level. Complete charging will take 2 to 3 hours. The advised rate of charging an energy cell should be between 0.5C and 1C. The efficiency charge is around 99%, and the battery stays cool during charge.
A complete charge will occur while the cell reaches its threshold voltage as current drops up to 3%. Also, a battery is fully charged when levels of current cannot reduce any more. This condition is caused by an increase of self-discharge. Moreover, increasing the charge current will not fasten full-charge by much.
Lithium rechargeable batteries do not need to be charged fully like lead-acid batteries.it is better not to charge it completely since it stresses the battery’s voltage. Removing charge saturation or having lower voltage will add the battery life but lower run time.
The fact remains that the best lithium rechargeable batteries are costly than other types of batteries. Some are three times expensive hence the price can turn you off. However, you can purchase other batteries for small devices like clocks and remote controllers. This is because the devices will not need to be recharged frequently because they do not consume much energy. Conversely, in case you love RC race car, photography, or use other devices that consume more power, then a lithium rechargeable battery is worth to buy. All lithium-based brands give amazing results seeing that they work for many years. Lastly, you will not only get satisfied but also helping the environment.
