Pre-Winter Maintenance: How to prep your batteries before the freeze hits! ❄️⚡

With winter temperatures dropping, taking a few proactive steps today will save your flooded deep-cycle batteries from permanent cold-weather damage!

When a flooded battery sits discharged, its internal fluid becomes mostly water. In freezing conditions, that fluid turns to ice, expanding and cracking the plastic case while destroying the lead plates inside.

4 Essential Steps to Winterize Your Battery Fleet:

🔋 Keep SOC High: Store batteries at 100% state-of-charge. A full charge keeps the freezing threshold down near 80F.
💧 Top Off Fluid Properly: Check electrolyte levels and top off with distilled water before charging. Charging mixes the acid and water together so pure water doesn't sit on top and freeze.
🧼 Scrub Terminals & Cases: Wash off dirt and corrosion with baking soda and water to prevent self-discharge during winter storage.
🔌 Cut Parasitic Draws: Disconnect main battery cables or turn off master switches on equipment stored for the off-season.

Protect your total cost of ownership with smart cold-weather care! 🇺🇸🔋

Preventative Care: Don't let chronic undercharging kill your battery pack! 🛠️⚡

Are your deep-cycle batteries running out of juice faster than they used to? Chronic undercharging might be the culprit.

When deep-cycle batteries are repeatedly disconnected before reaching a true 100% charge, sulfate remains trapped on the lead plates. Over time, these crystals harden, permanently reducing your battery's ability to hold energy.

How to spot an undercharged battery:
1️⃣ Dropping Specific Gravity: A hydrometer check shows low specific gravity (below 1.225) even right after a charging cycle.
2️⃣ Early Runtime Fades: Your equipment struggles to make it through a standard workday.
3️⃣ Voltage Drops Under Load: The battery shows good rest voltage, but plummets the moment the motor draws power.
4️⃣ Charger Mismatch: The charger is shutting off early or isn't outputting the correct voltage curve for your battery pack size.

The Fix: Make sure operators allow chargers to run through their full automatic cycle without interruption. Running a scheduled equalization charge also helps clear mild sulfation and re-balance cell capacities across the entire pack! 🇺🇸🔋

Pro-Tip: How to quickly identify and read your U.S. Battery AGM date codes. 🔍

Whether you are managing a fleet of commercial floor scrubbers or prepping your recreational vehicle for an upcoming road trip, tracking the age of your power assets shouldn't be a guessing game.

To simplify maintenance logging, all U.S. Battery sealed AGM lead-acid batteries feature a permanent date code stamped directly right onto the battery's top cover.

Depending on your unit, it will follow one of these two structures:
1️⃣ DDMMYY-LM: Day, Month, Year format.
Example: 150224-LM indicates a manufacturing date of February 15th, 2024.

2️⃣ CYYMMDD: Year, Month, Day format.
Example: C240215 indicates a manufacturing date of February 15th, 2024.

Regularly logging these codes during routine equipment checkups helps you anticipate future battery needs, verify warranty coverage, and ensure your charging systems are calibrated correctly to prevent unexpected power drops.
