Everything You Need to Know About Flooded Battery Maintenance

Did you know that a flooded battery lasts between 4 to 8 years while a gel deep cycle only lasts between 2-5 years? The lifespan will completely depend on how it is being used, charged, and maintained. You want to make sure that you follow a few top tips when caring for your flooded deep cycle battery.

Inside the battery is a particular electrolyte made of distilled water and sulfuric acid mixed in the right proportion. Over time, due to weather and operating conditions, the water may evaporate, and the level of liquid in the battery decreases.

If the electrolyte level is lower or higher than it should be, this may damage the battery. Without liquid to cover them, the lead plates inside the battery begin to be exposed. That is why regular checking and adjustment as needed is recommended. Keep reading to learn a few maintenance tips that will help keep your batteries in tip-top shape.

1. Add Distilled Water

Every 4-6 weeks, you want to take the time to add distilled water to keep them functioning properly and to stay healthy. Don’t ever use non distilled water (tap water) because it will introduce contaminants and small particles that will weaken the battery chemistry.

Check the battery’s water levels every 15-30 days and make sure to refill it as necessary. The watering schedule will depend on your local climate, the application, and the charge settings. Keeping a log will help you keep track of how often the batteries have to be refilled.

Make sure to add water to just below the maximum water level line. You never want to overfill past that line because it can cause you headaches in the future, and it can even create a safety hazard.

2. Electrolyte Fluids

Flooded batteries have electrolyte levels that have to be checked at least every 2/3 months. Look for one to three covers where the electrolyte fluid goes to ensure that the levels are where they need to be. Over time these fluids evaporate during the charge and discharge process.

3. Refill Tip

If you have to refill the water levels, you always want to wait until the charging is complete before you refill; if you add water before an incomplete charge or an incomplete charge, it can cause the gases to expand and damage the charging process.

Advantages of Flooded Batteries

One advantage of flooded batteries is that they are inexpensive. Most people choose them because they cost a lot less than other batteries.

Something else that makes them a better option is that they have a long deep discharge life cycle. They have more electrolyte than other battery options, which also gives them a good deep discharge recovery. This also acts as a heat sink to help keep the batteries cool to keep them from overheating.

Another pro is that flooded deep cycle batteries last longer than sealed batteries, and they are also much easier to troubleshoot. You can also view more differences between battery options right here.
