Always check the location of the battery terminals, so that there is no risk of corrosion or rusting due to the possibility of moisture.
If it is rust, wipe it with a wire brush, which will reduce the level of connection between the braces and the pole of the batteries.
Periodically check connections to avoid loosening them.
2 Avoid excessive discharging batteries.
Battery status or State of charge (SOC) is important. Discharging or overheating of solar cells has a direct impact on their life span. The general rule is that solar batteries should not be discharged by more than 50%. Of course, there are some newer solar-powered solar cells, such as Deep-Cyclone batteries, so that more than 70 percent can be discharged without damage and life-span. To protect the batteries from overheating, some inverters will be able to disconnect the system if the voltage is low, called Low Voltage Disconnect (LVD), which prevents damage to the batteries.
3 Ensure the battery is fully charged:
The best way to increase the life of your batteries is to charge 100% of the battery at least once a week! Naturally, the number of days the batteries are in 100% full charge life will last longer. For accurate monitoring of the batteries, some of their monitoring equipment can be used or the charge status of the batteries is known by controller charging, so if the charger is in the float state, it means that the battery is fully charged.
4 environment temperature:
The ideal temperature for keeping the acid-soluble solar batteries is at 25 ° C. If the batteries are placed in cold weather, the capacity of the batteries is significantly reduced.
For example, suppose we have a 1,000-amp battery at room temperature (25 ° C), if the same bank sets the battery at -20 ° C, we’ll cut it by 30% and drop it to 700 amps. So finding the right place for a bank of batteries can help reduce capacity and, consequently, life span.
At very cold temperatures, the best type of battery is nickel-cadmium (NiCad) batteries, which have a very high resistance to freezing, but they are also much more expensive compared to lead acid batteries.
5. Date of manufacture and expiration of the battery:
The important thing to look at before purchasing batteries is the battery history and their expiration date. It should not be too long since the batteries were built, otherwise the batteries do not have full health and the life span of the antenna has fallen sharply.
