1.How do you define OEM battery packs, and how are they different from non-OEM battery packs?
OEM is known as Original Equipment Manufacturer.
This Signifies the company is the original manufacturer of the battery, and it is not provided by any third party and sold to customers under the company’s own name.
On the other hand, Non-OEM signifies the manufacturing from a third company by doing reverse engineering to the original battery chemistry.
They are neither of the same quality as of OEM battery pack nor are their performances compatible as compare to OEM battery packs.
These third companies involved aren’t trustworthy; you can’t put your trust and cost to an unreliable manufacturer.
They are neither of the same quality as OEM battery pack nor are their performances compatible compared to OEM battery packs.
If you have battery packs from such manufacturers, it might lead to your devices’ critical issues. There isn’t any warranty from such manufacturers, because they don’t have their research and development to back their designs and specifications.

You can also give dispose of batteries for recycling because they contain recyclable materials.
14.What Should I consider about the shipping of lithium-ion battery packs?
You should consider following regulations while buying, selling, or shipping lithium-ion batteries.
United Nation Regulations
Lithium cells and batteries will be exposed to the tests, as needed by unique arrangements 188 and 230 of the Model Regulations preceding a specific battery or cell type vehicle.
DOT-Rule Update 9/28/06
This standard forced a restricted disallowance on contribution for transportation of essential lithium batteries and cells as the load on board traveler conveying airplane and gear containing or pressed with enormous lithium batteries.
This standard applies to both international and local traveler conveying airplane
entering, leaving, or working in the United States and to people offering essential lithium batteries and cells for transportation as freight on any traveler transferring airplane.
15.Are TLH OEM battery packs brand new?
Yes, every battery comes to you with a “born on” label, ensuring your new product.
16.What are the maintenance needs for the OEM battery pack?
Your OEM batteries require no big maintenance, such as effects of temperature variations and matching the liquid point.
Device connections to the battery should be firm and steady, and connections should be corrosion-free.
Check voltage levels on regular basis; if your battery shows voltage less than 13.28 V, then it’s in a state of discharge, and it needs to be a charge.
If there is a battery left in the state of discharge, then it can lead to damage or life shortened.
17.Can OEM battery packs be installed at any desired place?
Yes, your OEM battery pack can be installed at any desired place.
18.What are volts and milliamp-hours for a lithium-ion battery pack?
Lithium-ion batteries have two ratings, volts and amp-hours (AH).
Amp-hours are also known as (mAh).
Amp-hour is known as the amount of battery your battery can store.
In other words, it is known as the number of hours a battery can withstand.
MAH rating of variation is not a big problem, but voltage rating should be in a sustainable range.
Your battery rating should not exceed the rated battery rating.
For a better understanding of these concepts, please go through the following videos.
19.What is the standard lifetime of your OEM battery pack?
The battery life depends upon the charge-discharge cycle, and it sets in between 200 to 900 charge-discharge cycles.
This is the time in between 1.5 to 3 years, depending on the usage of the end customer.
If the frequency of charge and discharge cycles are more, then the battery will lose its life more rapidly.
20.How will OEM battery packs help you accelerate your renewable energy businesses?
The world is moving to renewable energy resources, and if you are an organization of renewable energy, then we are the one you are looking for.
We appreciate and motivate such businesses, and we cooperate with such businesses to provide them with the best rates and facilities to promote green energy.
21.What is the difference between Liquid and solid lithium-ion OEM battery pack?
Firstly in solid-state batteries, there are both solid electrolytes and electrodes.
On the other hand, the liquid battery pack has solid electrodes and liquid electrolyte.
Solid electrodes include polyesters, phosphates, nitrile-based, oxides, polyurethane, sulfides, etc.
The most widely used electrolyte in liquid battery packs is lithium salts in organic solvents such as LiPF6.
For your reference, please visit the following video for lithium-ion battery understanding; https://www.youtube.com/watch?v=VxMM4g2Sk8U.
22.How do you define the capacity of the OEM battery pack?
This is the amount of electricity define as the active material in the battery which can participate in the reaction of electrochemical.
This is known as the charge a battery can hold after the charging.
23.How do you define the design capacity of an OEM battery pack?
It refers to the active material present in the battery, which is used to calculate the capacity of the battery from electrochemical theory is known as design capacity.
24.What is the rated and actual capacity of an OEM Battery pack?
Rated capacity is provided by the customers, which manufacturers need to hold.
It is the requirement for the manufacturing and designing as well as the specification of charge and discharge of the battery.
On the other hand, the actual capacity is known as the discharge of a battery under particular discharge conditions.
25.Can you connect two OEM battery packs having different capacities, performance, and made?
No, this will cause an imbalance to the battery packs.
Mixing of two non-identical OEM battery packs will lead to underperformance as well as lead to battery leakage.
For Optimum results, use batteries of the same cells, voltages, brand, and chemistry
26.What are the reasons for the distorted belly of an OEM battery pack?
Following are some of the reasons for it;
1）Due to very high ambient temperature
2）Short circuit of single cell
3）Very high acid density
4）Extreme absorption of acid as well as separator quantitative deviance
5）Rupture of shell
6）Safety valve pressure is varying.
27.Why does the battery charging heat occurs in OEM battery packs?
Here are some of the reasons for battery charging heat. In batteries, we have a charging and discharging process in which chemical energy is converted to electrical energy and electrical energy is converted to chemical energy.
It is not unusual for the battery to heat up, but in times of high temperature, you should consider checking the charging current. Is it too high, or is there any short circuit on the inner side of the battery?
You should check the relationship between heat generated and the amount of the electrolyte in the battery pack.
In the case of insufficient electrolyte, the resistance of the internal battery will increase, resulting in heat up of the battery and the rise of the terminal voltage during the time of charging.
Aging and drying of the battery, as well as internal short circuits, are also the other reasons for the battery charging heat.
28.How can you increase voltage output and capacity by the arrangement of OEM battery packs?
We use a series combination of OEM battery packs to add up voltages; each cell sums up to the desired voltage.
On the other hand, the parallel combination is used to attain the higher capacity of battery packs; it is achieved by summing up the total ampere-hour (Ah).
Another connection for the arrangement of OEM battery packs is a parallel series connection. The Power of the battery is equal to current time’s voltage. For example, a cell having 3.6 V and 3,400 mAh results in 12.24 Wh. This combination needs continuous examination to avoid any excess of voltage and current parameters.
Below are the figures for series and parallel combination of cells and their resulting impact on capacity and voltages.
29.How to apply for a visit to witness the production of OEM battery packs?
For visiting the plant premises, you should contact the customer service of TLH, who will inquire about a few things related to your visit.
After we are done with the prerequisites of the visit, then we will get back to you with a suggested date and time of visit.
To confirm your visit information and call us before coming to the plant.
