For many anglers, the end of the season means putting gear into “hibernation.” However, your FishPRO camera‘s battery requires a little more than just a dark shelf to stay in peak condition. Since our cameras utilize Lithium Polymer (Li-Po) technology, they require specific care to ensure that a 9-month break doesn’t result in a dead battery next spring.

1. The “Storage Charge” Sweet Spot

A common mistake is storing a battery 100% full. In the world of high-performance Li-Po cells, a 100% charge is like a tightly wound spring—it puts maximum chemical stress on the internal components. Over a long period, this “high tension” can lead to cell swelling (gas buildup) and permanent capacity loss.

Conversely, a 0% battery can fall into a “deep discharge” state during storage, causing the protection board to lock the battery permanently for safety.

• Professional Recommendation: Always store your battery at 50%–70% charge. Think of this as the “neutral gear” for your battery; it minimizes internal pressure and effectively eliminates the risk of swelling, ensuring the cells stay flat and healthy.

2. Combatting Natural Self-Discharge

Even when powered off, Li-Po batteries experience a very slow natural energy leak known as self-discharge. If left unmonitored for 9 months, that tiny leak can drain the battery below its safety threshold.

• The Quarterly Check: Set a calendar reminder to check the battery level every 2–3 months. If the level has dropped, top it back up to roughly 60%. This keeps the ions active and prevents the battery from “falling asleep” permanently.

3. Thermal Management: Cool & Dry

Temperature is the invisible killer of battery longevity. High heat accelerates the chemical degradation of the electrolyte inside.

• Ideal Environment: Keep your gear between 10°C–25°C (50°F–77°F).
• Avoid: Non-insulated garages, attics, or damp basements. A stable, room-temperature environment in a dry cupboard is the best way to prevent terminal corrosion and internal aging.

4. Pre-Season “Wake-Up” Call

When the ice melts and you’re ready to hit the water again, your battery needs a “warm-up” to reach full efficiency.

• The Calibration Cycle: Before your first big trip, perform one full charge-to-discharge cycle. Charge it to 100%, run the device until the battery is low, and then recharge it. This “stretches the muscles” of the battery chemistry, ensuring accurate power readings and peak runtime for your first day back.

Technical Summary: Proper storage is the difference between a battery that lasts two seasons and one that lasts five. By following the 50%-70% rule, you aren’t just storing your gear—you’re protecting your investment.

Tight lines, and we’ll see you on the water next season!
