7 Points to Ask About OEM Lithium Batteries

The Ultimate Guide to Choosing a Lithium Battery Supplier

1. WHEN trying to find out lithium battery factory was founded, you can inquire about how long they have been in business, how long they have been serving the lithium battery industry, and whether they have supplied batteries to major OEM customers. You can also ask if they offer a combination of battery types, such as liquid-rich lead-acid, AGM, AGV Battery, and lithium-ion batteries. If the supplier is an emerging company, just starting out in the new energy space, or has not yet supplied batteries to OEMs, you may want to consider further.

In contrast, well-established and experienced companies are familiar with the lithium battery industry, and they manufacture and sell a diverse range of lithium battery products. These companies typically have a deep understanding of the issues that can affect battery performance and life, and have incorporated solutions to these issues into their products.

2. HOW long have you been working in lithium ion technology? Again, if the answer is only a few years, then the company probably has a lot to learn.

3. WHAT kind of customer support do you offer? Make sure the company has customer support hotlines in the U.S. and Europe staffed by real people who can answer questions and help your technicians solve problems. Ask if 24/7 support is available and if the staff includes a representative responsible for lithium-ion products. Many newcomers to the market simply do not have the infrastructure to provide this level of service.

4. HOW do you support the distributors who sell your products? You don’t want to lose contact with a vendor simply after selling a product. To avoid endless phone calls and long wait times, you should look for manufacturers that maintain systematic communication with their dealers. Ask if the manufacturer has a network of authorized dealers through which it trains dealers to sell its products and provides them with the information and materials they need.

5. HOW do you ensure the quality and certification of your batteries?  It takes a lot of time to find a reliable Lithium Battery Supplier in a vast network. Whether you are an engineer or have customization needs, high quality lithium batteries with full certification are essential. Ask the supplier what type of cells they use, there are three types of cells: steel casing cylindrical, soft pack aluminum-plastic film and square aluminum casing.

Ask if they are ISO:9001 certified and if they are licensed according to the requirements of your local market.

6. WHAT makes your batteries different from others in terms of design and engineers? Look for products with UL1973 certificationand at least an IP67 rating. This helps protect the battery from vibration, water and dust damage and can extend its life. Make sure the battery is recessed and modular and expandable.

Ask how the design of the battery moves the harmful heat it generates away from the battery. Most Lithium Battery Supplier accomplish this with inexpensive components called heat sinks because they are easy to make and add.

But heat sinks shouldn’t be the only method of heat management. Well-made batteries reduce the amount of heat generated and are designed to cool naturally. This requires more engineering expertise, but it can improve efficiency, increase safety and extend battery life.

7. WHAT safety features are built into your batteries? Look for batteries that use lithium iron phosphate, one of the most stable lithium-ion battery chemistries. Make sure your Lithium Battery Supplier is using a good BMS. lithium iron phosphate batteries have a BMS protection board that can instantly and accurately grasp the status of the battery. During the charging and discharging process, it collects the terminal voltage, temperature, charging and discharging current and total voltage of each battery in the battery pack in real time, so as to prevent the battery from overcharging or over-discharging. This in turn improves the efficiency and service life of the entire lithium battery.

Stocking batteries based on pricing alone is a big mistake that could affect your profits. Be sure to compare manufacturers’ experience, support services and products. Investing a little time in your decision making can pay big dividends in sales, service and customer satisfaction.
