Replacing and Maintenance Tips for Fish Finder Batteries

  • Use LiFePO4-Compatible Chargers Only: Always use a charger designed for lithium batteries. Wrong chargers damage the battery and reduce its lifespan.
  • Follow the 20-80 Charging Practice: Keep your battery between 20% and 80% charged during regular use. This extends battery life. You can charge to 100% when needed.
  • Store at 50-60% Charge for Long Periods: If storing for winter, charge to 50 to 60% and keep in a cool, dry place. Don't store it at 0% or 100%.
  • Clean Terminals Regularly: To avoid corrosion from saltwater, wipe terminal connections with a dry cloth before each season and check that bolts are tight (10 to 12 Nm torque).
  • Don't Charge in Extreme Cold: Avoid charging when the battery temperature is below 0°C. Let it warm to room temperature first.
  • Check Voltage Monthly: A fully charged 12V battery should read 12.8V-13.2V. If it's lower, contact support or test your charger.
  • Use a Protective Battery Box: Use a dedicated battery box to protect from water spray, impacts, and movement. IP67 rating protects against water jets, not full submersion.
  • Replace Damaged Cables: Check power cables for cracks or fraying. Damaged cables reduce power and create safety risks. Use marine-grade replacements.

When to Replace Lithium Fish Finder Battery?

  • Your fishfinder battery runs less than 50% of the original runtime per charge.
  • The battery drains quickly or won't stay charged even after a full charge cycle.
  • It takes much longer to charge than usual, or the charger shows an error message.
  • If there are visible cracks, bulging, leaking, or warping of the battery case.
  • The fish finder often shuts down or restarts while running.
  • BMS shows repeated warnings or error messages despite proper handling.
  • The battery is beyond 10 years old (even with good care).

Frequently Asked Questions

Are Lithium Batteries Good for Fish Finders?

Yes. LiFePO4 lithium batteries keep your sonar bright and GPS accurate all day long, unlike lead-acid that fades as it drains. They're lighter, last 10+ years, and work with all major brands like Garmin, Lowrance, and Humminbird.

What is The 80-20 Rule for Lithium Batteries?

Keep your battery charged between 20% and 80% during regular fishing trips—this extends battery life to 6000+ cycles instead of 4000. You can charge to 100% before a full-day trip when needed.

How Long Does a Fish Finder Battery Last?

Runtime depends on your fish finder's power draw and battery capacity. A Garmin Striker drawing 0.25A gets 240 hours on a 60Ah battery; a Livescope drawing 3.5A gets about 17 hours. Check your fish finder manual for the exact power draw.

What Size Battery for a Fish Finder?

For kayak anglers, a 60Ah battery works fine. For all-day boat trips, you can use 100Ah. For Livescope or multi-day fishing, you can pick 150Ah. Always pick a size that gives you 20% extra capacity beyond what you think you'll need.

Can I Use a Lithium Battery for My Fish Finder?

Absolutely. Enexer LiFePO4 batteries work with Garmin, Lowrance, Humminbird, Vexilar, and all other major brands. Just use a LiFePO4-compatible charger, and you're ready to fish.

Can I Connect a Fish Finder to a Trolling Motor Battery?

Not recommended. Trolling motors draw heavy current (20-60A) that causes voltage sag, dimming your sonar display and causing shutdowns. Use a separate dedicated battery for your fish finder.

What Not to Do with a Lithium Fish Finder Battery?

Avoid charging the battery in temperatures below 0°C, using chargers not designed for lithium iron phosphate batteries, or storing it at 0% or 100% charge for extended periods. Additionally, never crush or drop the battery. Since it’s sealed, any damage may require a replacement.

How Do I Care for My Battery When Ice Fishing?

Keep your battery in an insulated battery box and store indoors between trips. Charge it to 50-70% before winter storage and warm it to room temperature before charging in cold weather.

Can I Use the Same Battery for Different Fishing Setups?

Yes. A 12V battery powers your fish finder, GPS, and accessories on both kayaks and boats—just move it between setups. Use a battery box to protect it during transport.

Are Lithium Fish Finder Batteries Safe?

Yes. LiFePO4 is non-flammable and non-toxic with built-in BMS protection against overcharge, short circuits, and overheating. Enexer batteries meet all CE, MSDS, UN38.3, and RoHS safety standards.

What Temperature Range Does Enexer Battery Work In?

Enexer batteries discharge reliably from -20°C to 65°C, perfect for Canadian winters and ice fishing. Avoid charging below 0°C; let the battery warm up first.

Can a Dead Fish Finder Battery Be Revived?

Sometimes, if the battery went fully flat. Try charging it with a LiFePO4-compatible charger. If it still won't hold charge, replace it—trying to revive a dead battery isn't worth the risk.
