AGM batteries are recognized for their low self-discharge rate, spill proof nature and hence are suitable for use in many applications. However, to get the most out of your AGM battery and make it last as long as possible while delivering optimal performance, you need to follow several key rules of care. No matter if you are an owner of an AGM battery for your car, boat, or solar power system, these tips will help you to get the most of your battery investment.
Proper Charging Techniques
This is one of the key considerations when it comes to the proper care of your AGM battery and this is through the right charging methods. AGM batteries have limitations to charging, especially overcharging as this will cause damage to the cells and affect the total lifespan of the battery. To ensure that you do not overcharge the battery, it is recommended that you use a smart charger that is able to change the voltage as soon as the battery is fully charged. This helps to charge the battery to the optimum level without causing any detrimental effect.
However, there is a charging cycle that should be observed, and it is not advised to leave your battery on the charger for a long time. Charging the battery beyond this point will cause it to heat up, which can lead to some malfunctions and a reduced lifespan. It is therefore important to use a good charger that is compatible with AGM batteries in order to maintain your battery in the best state.
Avoid Deep Discharge
Even though AGM batteries can take deep discharges better than conventional lead-acid batteries, deep discharging the battery often will shorten its lifespan. The best practice is to never let your AGM battery go below 50% of its capacity if at all possible. If a battery is drained to very low levels, then the cells are put under pressure, which will cause them to degrade faster.
For applications that will be used more often, like renewable energy systems, it is advisable to incorporate a battery monitor to check on the charge and avoid deep discharge. If the charge is kept constant, then the AGM battery will last longer and maintain the range that is most suitable for it.
Daily/Weekly/Monthly Inspection and Cleaning
While AGM batteries do not require any sort of maintenance, it is recommended that the battery terminals and connections be checked occasionally for signs of corrosion or wear. Damaged terminals cause poor electrical connection, thus reducing the efficiency of your battery. Wipe the terminals with a paste of baking soda and water, and check that all the connections are tight.
Maintaining the terminals clean from corrosion and other debris is important for the battery to provide the highest amount of power and efficiency possible. Also, it is recommended to check for any cracks or leakage on the battery housing from time to time so that you can seek the necessary repair before they become serious.
Store in a Cool, Dry Place
Before you decide to store your AGM battery for an extended period, ensure that you store it in a dry and cool area. Excessive heat is one of the biggest threats to the battery, which will cause a reduction in both efficiency and battery life. High temperatures increase the rate of self-discharge and have a detrimental effect on the battery cells.
This is also why it is advisable to occasionally charge the battery during storage to ensure it does not discharge too much while not in use. A fully discharged AGM battery that is not used for a long time loses its capacity and even fails to charge properly.
Conclusion
If you follow these simple maintenance tips, you can increase the lifespan of your AGM battery and get the most out of it. It is crucial to verify the state of charge, not to discharge deeply, and clean the terminals to get the most out of your AGM battery. Regardless of the type of battery you are using for backup power, automotive, or renewable energy, you will get the best value for your money if you take good care of the battery.
