Как выбрать АКБ для ИБП

Different batteries can have different stanby use voltages. Some have values ​​between 13.38V and 13.62V, while others have values ​​between 13.5V and 13.8V. UPSs are similarly well-equipped. Good UPSs, such as those from APC, provide a charging voltage of 13.52V, while many cheaper ones provide 13.8V. Therefore, batteries with a stanby use voltage of 13.38V to 13.62V quickly die in a UPS with a charging voltage of 13.8V. Also, pay attention to the battery terminals. If the terminals are F1, then the battery is weak and intended for a fire alarm system. UPS batteries have F2 terminals (they are slightly larger than F1).
