1. Do not consume more than 10% of the battery life current according to the international specifications of the manufacturer installed on the battery.
  2. Example: If you have a 200Ah battery, it is not permissible to load it more than 20 amps, which is enough to run 7 continuous hours.
  3. Do not make shorts on the battery terminals, even for a moment.
  4. If the battery is not completely discharged, at least 30% of the battery charge remains stored in it.
  5. Charge the battery for 24 hours before use.
  6. Do not put batteries in hot places, but the temperature must be maintained within 25to 30 
  7. degrees Celsius.
  8. In general, it is not recommended to have more than 4 strings in parallel
  9. Use the same wire size and length between the batteries and make sure there is no wear.
  10. Do not connect new and used batteries, because any slight difference in voltage or age leads to poor performance and possibly complete failure.
  11. When operating refrigerators and washing machines, the starting current must be taken into account.
  12. From my relatively practical experience, it is not permissible to use external chargers that are not good because they are the main cause of damage to the batteries and their early failure
