Li-ion Battery Pack  FAQ Guide

TLH manufactures Li-ion batteries for the last 15 years, we have equipped our system with digital certifications and quality tests.

We understand the challenges of our B2B customers, and for this, we have tried to summarise all of your queries in the following Li-ion FAQs guide.

In case of any queries, please feel free to connect with us.

1. How is Li-ion battery packs better than other rechargeable batteries?

Li-ion batteries comprise positive plates (cathodes) as well as negative plates (anodes).

These plates act as protecting separators to keep away from short circuits between the negative and positive plates.

Lastly, electrolyte, which is the conductive fluid, is dissimilar to overwhelmed lead corrosive batteries.

There is no free fluid in LiFePO4 batteries.

A Li-ion battery contrasts in the materials utilized for the previously mentioned segments, particularly the cathode and the cycle embraced during charge and recharge.

A corrosive lead battery attempts compound responses, which change their segments.

Lithium moves particles during the charge and release measure leaving all the other things the equivalent.

Li-ions have several advantages over other rechargeable batteries;

Li-ion batteries consist of higher energy density as compare to most different sorts of rechargeables batteries.

This implies that concerning size and weight, they can maintain more energy compared to other battery-powered batteries.

They also work at higher voltages than other rechargeables, commonly about 3.7 volts for lithium-particle versus 1.2 volts for NiMH or NiCd.

This implies a solitary cell can frequently be utilized as opposed to numerous NiMH or NiCd cells.

Li-ion batteries additionally have a lower rate of discharge as compare to other powered batteries.

This implies that whenever they are charged, they will hold their charge for a more extended time than different sorts of battery-powered batteries.

Simultaneously, if we discuss NiMH as well as NiCd batteries,

then they can lose in the range of 1-5% (contingent upon the capacity temperature) regardless of whether they are not introduced in a gadget.

Li-ion batteries will hold a large portion of their charge even following quite a while of capacity.

So in the synopsis, li-ion batteries can be more modest or lighter, maintain higher voltage, and keep the charges longer than other types of batteries.

3. What is the optimum way to store  Li-ion battery packs?

Our technical team has lined up five different ways for storage of Li-ion batteries.

We are expressing those ways here so that not only business customers can take guidelines, but also they can guide their customers regarding it.

  1. Maintain your charge level at 40% in case of storage timelines

it’s ideal for charging a battery before use altogether, but it is not desirable that you fully discharge a battery so that you can charge it at once.

This will cause particular damage to battery capacity.

The best device manufacturers keep their lithium batteries at around 60 degrees and on a 40% level charge.

The 40% charge permits a steady condition regardless of whether it implies a degree of self-discharge.

Few reserve charges are essential to maintain a battery, and it also secures the battery protections during extensive stretches of capacity.

  1. Don’t Keep your Li-ion batteries at extreme temperatures

Li-ion batteries aren’t fond of heat.

In the case of keeping a lithium battery at a steady high temperature, their life expectancy, run time, and charge limit diminish altogether.

  1. Note the manufacturing date of the Li-ion battery

Did you locate a modest cost for an extra lithium-particle battery on a website?

Or on the other hand, did you discover a massive deal on matured or aged lithium batteries in an electronic rebate store?

This may sound amazing, and it seems that you have saved thousands of dollars, but still, you need to consider this deal.

Continuously check the maker date preceding any lithium battery buy, and never buy a lithium battery until you are prepared to utilize it.

The life of a lithium battery begins declining the subsequent it leaves an industrial facility.

You can hope to lose around 20% of a li-ion battery’s charge each year from its unique production date regardless of how well you deal with your battery.

It’s ideal to ensure the production date falls inside a time of the date of your buy.

  1. Avoid overcharging and over usage of Li-ion batteries

At the point when a Li-ion battery-based camera isn’t being used, it’s ideal for eliminating the L-ion battery from the camera unit.

It’s likewise best to eliminate the li-ion battery when a camera is running on an energy connector.

If you have an extra lithium-particle battery, utilize one for the camera unit and keep the other cool by putting it in a fridge.

On the off chance that you leave a li-ion battery inside an advanced camera battery compartment consistently, the battery will get unusable at a lot quicker rate.

It’s ideal for giving your computerized camera a breather by eliminating the battery each time it’s not being used.

  1. Avoid usual discharging of your Li-ion batteries

You can quickly recharge your li-ion battery partially because li-ion batteries don’t have any memory effect.

It would help if you had frequent partial discharge with many recharges because this is relatively healthier for battery life.

Usually, high rates of discharges are responsible for damages, and you should opt for the frequent practices of slower charge rate; this will enhance Li-ion batteries’ lives.
