Battery Packs Buying Guide
Battery packs often contain over one identical battery sold together in a package. The price of such battery packs is usually lower than their individual prices. Battery packs often come in numbers of 2, 3, 5 and sometimes even more. Thus, most of the users prefer to go with battery packs, rather than buy individual ones. This guide focuses on the few benefits of buying battery packs, especially the Li-ion batteries. It also lists some factors that you should consider before buying them.
A lithium-ion battery or Li-ion battery is a type of rechargeable battery. Lithium-ion batteries are usually used for compact electronics and electric vehicles. They offer various advantages such as higher energy density, voltage capacity, and lower self-discharge rate. But all these factors can be slightly confusing while you are looking to buy battery packs. So, we hope this guide helps you in selecting the right battery.
Benefits of Buying Battery Packs
High Energy Density
The high energy density is one of the chief benefits of lithium-ion batteries. From devices to electrical vehicles, many applications require batteries with high power density. You can find types of lithium batteries ranging between low, high and higher density.
Unlike other batteries where you need to check water levels, lithium-ion batteries don't require a check. They are simple to use and do not need any active maintenance.
One of the major issues with rechargeable batteries is the self-discharge feature. However, the levels of self-discharge in lithium-ion batteries are lower than other batteries such as Ni-Cad and NiMH. It is around 5% in the initial 4 hours after being charged. Then it falls to around 1 or 2% every month.
No Need for Priming
Some rechargeable batteries need to be primed when they get their first charge. However, lithium-ion batteries do not require any priming as they are available operational and are ready to use.
Factors to Consider While Buying Battery Packs
One of the major reasons people prefer lithium-ion batteries over other batteries is the high voltage rate. Not all batteries have the same voltage capacity. Thus, make sure to check it before purchasing. Maximum initial battery voltage (measured without a workload) should be at least 20 volts and nominal voltage should not be less than 18.
You need to make sure that you are investing in the battery with a longer shelf life. The average lithium-ion battery lifespan for a large-capacity battery pack should be as long as eight years or more.
The warranty for lithium-ion batteries is one of the major factors to consider. It protects you from potential defects that may occur, such as fires or damage from spills. There are different warranty periods for different parts of a battery. The warranty of Lithium-ion batteries varies according to the brands. Some popular brands provide around five to six-year of a warranty period.
The major disadvantage of lithium-ion batteries is their cost. Usually, they are 40% costlier than other batteries. This is a major factor to consider. Most of the battery packs are affordable and their durability makes them an economical option So, select the type and brand according to your budget.
Using lithium-ion batteries has grown significantly in recent years. They offer many distinct advantages over other forms such as high energy density and low maintenance. However, choosing the best one among various options, size and material become very confusing. Thus, along with the above factors you can consider other factors like the market review, return policy, etc.
