Technical Benefits & FAQs
When it comes to battery longevity, lithium iron phosphate (LiFePO4) batteries lead the pack. They are EV-grade LiFePO4 cells and up to 10-year lifespan, 4000+ cycles at 100% DOD, stable long-term charge and discharge. This makes them perfect for users who need durability and long-term reliability. If you're looking for a dependable option, Power Queen LiFePO4 batteries are designed for extended use and consistent performance. With a strong casing and high cycle life, these batteries are an excellent investment for anyone prioritizing longevity.
Testing a 12V lithium battery is simple with a multimeter. Set the multimeter to DC voltage, then connect the positive and negative probes to the corresponding terminals of the battery. A fully charged 12V lithium battery should show a reading between 12.8 and 13.4 volts. If the reading is lower, it could mean the battery is partially discharged or may be starting to degrade. Regular testing helps ensure your battery remains in top condition, preventing unexpected power issues. If you're unsure or need help, feel free to contact us, and we'll be happy to assist you with testing and battery maintenance tips.
The main difference between a 12V normal battery and a 12V deep cycle battery is how they deliver power. A normal battery, like a car battery, is designed to provide a quick burst of high power to start an engine, but it can't handle deep discharges well. In contrast, a deep cycle battery is built with thicker plates and is designed to provide steady power over a longer period. It can be discharged and recharged many times without damage, making it ideal for applications like solar power systems or RVs, where consistent energy over time is needed.

12V lithium batteries offer better performance, longer lifespan, and faster charging compared to traditional 12V lead-acid batteries. They're also lighter and more efficient.
For more details, read the article: Lead Acid vs Lithium Ion Battery: What's the Difference?
Yes. LiFePO4 is an intrinsically safe chemical and the most stable lithium-ion battery on the market. Power Queen lithium cells are certified by UL, FCC, CE, RoHS, and UN38.3 to ensure their quality and safety.
All Power Queen LiFePO4 batteries include an internal Battery Management System that protects against undervoltage during discharge, overvoltage during charge, overcurrent during discharge, overheating during charge and discharge, and short-circuit protection, which protects battery cells from damage.
In addition, Power Queen LiFePO4 Lithium batteries have been tested to be fireproof.
Yes, a 12V deep cycle battery is ideal for marine use, powering trolling motors and onboard electronics. Power Queen's Trolling Motor Lithium Batteries are designed for rugged environments, ensuring reliability for your boating adventures.
No, 12V lithium ion batteries require a specific charger designed for lithium-ion technology to prevent overcharging and ensure safety.
For more information, read about the article: Can I Charge a Lifepo4 Battery With a Lead Acid Charger?
Yes, 12V lithium ion batteries generally have a higher upfront cost but are more cost-effective in the long run due to their longer lifespan and lower maintenance needs.
