COMMON QUESTIONS
51R LiFePO4 battery FAQ
Will this fit every application that lists Group 51R?
Not automatically. Verify case dimensions, terminal orientation, hold-down, required cranking amps, charging-system compatibility, and any sensor or special connection used by the vehicle or boat.
Do I need a special charger?
Use a charger with a 12.8V LiFePO4-compatible charging profile and follow the PowerTex instructions. Avoid lead-acid-only reconditioning or desulfation modes.
What does the battery management system do?
The integrated BMS protects against overcharge, over-discharge, and short-circuit conditions while monitoring battery operation.
What does the built-in jump-start button do?
If low charge or BMS protection shuts down the main output, the top-mounted button provides access to emergency starting reserve. Recharge the battery and diagnose the cause after use.

What are the benefits of choosing Powertex's lithium car batteries over traditional lead-acid batteries?
Powertex Batteries' lithium car batteries offer numerous advantages, including lighter weight, higher energy density, longer lifespan, internal jump-starting, cutting-edge BMS, bluetooth connectivity and superior performance in extreme temperatures compared to traditional lead-acid batteries.
Do I need a special charger for Powertex Batteries car batteries?
Certainly, it's advisable to utilize a charger tailored for lithium batteries to uphold peak performance and safety standards. Employing a charger unsuited for lithium batteries could potentially lead to battery damage or safety risks. Please note, this recommendation pertains to external charging or tender applications, distinct from the vehicle's alternator. Rest assured, our batteries are engineered to seamlessly interface with standard car alternators.
Can I jump-start a vehicle equipped with Powertex Batteries' lithium car battery?
Using a jump starter with our batteries is unnecessary, as they are equipped with a built-in button that effectively acts as a jump starter. Just press the button, and you can start your car independently, anytime, without assistance from anyone else!
Are Powertex lithium car batteries safe to use?
Yes, Powertex Batteries' lithium car batteries are crafted with integrated safety features to ensure safe operation. When properly handled and installed, they present minimal safety concerns. Our choice of lithium chemistry, lithium iron phosphate (LiFePO4), ensures utmost safety, distinct from the lithium chemistry commonly found in cell phones and other devices.
How long can I expect Powertex Batteries' lithium car batteries to last?
Powertex Batteries' lithium car batteries are engineered to last between five to ten years or beyond, contingent upon factors such as usage patterns, charging routines, and environmental circumstances. Designed to deliver enduring performance and unwavering reliability, they outlast conventional lead-acid batteries, which typically endure approximately three to five years.
Can I use a Powertex car battery for racing or high-performance applications?
Yes, Powertex batteries are a popular choice for racing and high-performance vehicles due to their lightweight design and high energy density. However, it's essential to choose a battery with the appropriate specifications and ensure it meets the requirements for your specific application.
Do I need to code Powertex Batteries lithium car battery when installing?
Though not every battery replacement necessitates programming, certain newer models from Audi, Porsche, BMW, and similar brands are advised to undergo updates using a qualified scan tool programmer. This simple process guarantees alignment with the new battery's chemistry and capacity. Moreover, it alerts the alternator to the presence of the new battery, allowing for precise charging in line with its specifications and preventing overcharging or potential complications.
Are Powertex Batteries' lithium batteries environmentally friendly?
Yes, Powertex Batteries' lithium car batteries are more environmentally friendly than traditional lead-acid batteries. They contain fewer toxic materials and can be recycled, reducing their environmental impact.
Do Powertex Batteries require maintenance?
No, Powertex Batteries' lithium car batteries are maintenance-free.

How do Powertex Batteries perform in extreme temperatures?
Powertex lithium batteries excel in a wide range of temperatures but may be less efficient in consistently cold climates. If your car is regularly used in temperatures below 30°F, a lead-acid battery may be a better option, as lithium batteries can experience reduced efficiency in extreme cold. Powertex lithium batteries are designed to operate between -4°F and 140°F. While lithium batteries are more tolerant of temperature extremes overall, for colder climates, lead-acid may offer more consistent performance.
What should I consider before purchasing a lithium car battery?
Factors to consider include compatibility with your vehicle, voltage and capacity requirements.
What is covered under the battery warranty?
Our 5-year prorated limited automotive warranty covers any manufacturing defects that may arise during normal use of the battery.
