Q: Is the PowerTex LiFePO4 battery safe?
A: Yes, LiFePO4 is one of the safest lithium battery chemistries. It has built-in protections against overheating, overcharging, and short circuits, making it a safer alternative to traditional lithium-ion and lead-acid batteries.

Q: How fast does the PowerTex LiFePO4 battery charge?
A: LiFePO4 batteries charge much faster than lead-acid batteries, often reaching full charge in a fraction of the time, especially when paired with a lithium-compatible charger.

Q: Does the PowerTex LiFePO4 battery require a special charger?
A: While some vehicles can charge LiFePO4 batteries using their standard alternator, using a lithium-compatible charger is recommended to maximize performance and lifespan.

Maintenance Tips

• Use a Compatible Charger: Only charge the battery with a LiFePO4-compatible charger. Avoid using traditional lead-acid battery chargers, as they can damage lithium cells.
• Monitor Voltage Levels: A fully charged LiFePO4 battery should read 13.6V – 14.6V. Avoid discharging below 10V, as deep discharges can shorten battery life.
• Avoid Extreme Temperatures: Operate within the recommended temperature range. Extreme heat or cold can affect performance—avoid charging in freezing temperatures unless the battery has built-in heating.
• Secure Installation: Ensure the battery is properly mounted to prevent vibrations and movement that could damage internal components. Use appropriate brackets if necessary.
• Check and Clean Terminals: Inspect battery terminals regularly for corrosion or dirt buildup. Use a dry cloth or mild baking soda solution to clean them if needed.
• Prevent Deep Discharges: Keep charge levels above 20% whenever possible. LiFePO4 batteries last longer when they aren’t fully drained before recharging.
• Monitor the Battery Management System (BMS): If equipped, ensure the BMS is functioning properly to regulate charge levels, prevent over-discharge, and manage temperature protection.
• Disconnect for Long-Term Storage: If the vehicle is parked for extended periods, disconnect the battery and store it at around 50% charge in a cool, dry place to preserve lifespan.
• Check Alternator Compatibility: Verify that your vehicle’s alternator is compatible with LiFePO4 batteries. Some systems may require an adjustment to match the lithium charging profile.
• Handle with Care: Avoid short circuits by keeping tools and metal objects away from the terminals. Never drop or puncture the battery, as damage to internal cells can be hazardous.
