Frequently Asked Questions

The high cost of 12V lithium batteries can be attributed to several factors:  

  1. The extraction and refining of raw materials like lithium, cobalt, and nickel are expensive.  
  2. Significant investment in production processes and R&D drives up the final product price.  
  3. To ensure safety, lithium batteries require a BMS, which adds to manufacturing costs.  
  4. Lithium batteries have higher energy density and longer lifespan compared to traditional batteries, offering extended service time. These advantages have increased demand in energy storage systems and portable electronics, contributing to the price rise. 

Let’s first look at the advantages of 12V lithium batteries, mainly in comparison to lead-acid batteries:

In the same volume or weight, a 12V lithium battery can store more energy. It has an extremely low self-discharge rate, providing longer runtime for devices. Li ion batteries charge quickly and don’t require a cooldown period. They can be installed in any orientation and need no maintenance during use. Additionally, lithium batteries are an eco-friendly energy source.

While these advantages meet the needs of many users, the initial cost of lithium batteries cannot be overlooked. It takes a certain period of use to recover the investment.

In conclusion, whether a 12V lithium battery is worth buying depends on your needs. If your budget allows, the answer is yes.

The lifespan of lithium batteries varies between manufacturers. For example, Delong’s 12.8V lithium battery offers a 12-year lifespan and supports up to 6,500 cycles.

Common 12V batteries include lithium batteries, flooded lead-acid batteries, gel batteries, and AGM batteries. Among them, 12V lithium batteries have the longest lifespan.

When charging a 12V lithium battery, keep the following points in mind:  

  1. Use a charger specifically designed for lithium batteries, with CC/CV charging method.  
  2. Ensure correct connection between the charger and battery, matching the positive and negative terminals.  
  3. Charge in a well-ventilated area, and regularly check the battery’s charging status to avoid overcharging.

Try to avoid overcharging the 12V lithium battery. Doing so can reduce its lifespan and pose safety risks.

You can check if the 12V lithium battery is functioning properly by looking for the following signs:  

  1. Inspect for any obvious swelling, deformation, cracks, or leaks.  
  2. Check the terminal connections for corrosion, looseness, or other issues.  
  3. Measure the voltage with a multimeter—if it’s lower than normal, there may be excessive discharge or damage.  
  4. Monitor the charging time, charging status, and discharge conditions to see if they match normal behavior.  
  5. Check the BMS indicator light or status display for any error codes or warning messages.

If the 12V lithium battery is too low on charge or has been unused for a long time, you can try the following steps to revive it:  

  1. Connect the li ion battery charger to the battery’s positive and negative terminals.  
  2. Charge it with low current, while monitoring the battery’s temperature and voltage.  
  3. Once the voltage rises to normal levels, the battery is recovering.  
  4. Disconnect the charger as soon as the battery is fully charged.

A fully charged 12V lead-acid battery can be stored for 3 to 6 months. A 12V lithium battery, when properly charged, can be stored for 6 to 12 months.

Additionally, keep the battery in a dry, cool environment. Regularly check its condition and recharge it as needed to maintain performance and extend its lifespan.

AGM stands for Absorbent Glass Mat. It refers to a type of sealed lead-acid battery that uses fiberglass mats to absorb the electrolyte. Nowadays, many devices have upgraded to lithium battery systems.
