Reserve operating times for different alarm classes - overview

The table shows the requirements for backup operating time and recharging of batteries for different alarm classes.

Important

This is a guide and all times are approximate and may differ from actual times. Load, temperature and other factors come into play, which is why exact time can not be provided.

Applies to new batteries.

Amperage and batteries vary with configuration, check if the configuration can handle batteries and amperage.

* battery life depends mainly on ambient temperature and charging current. An AGM battery should never be charged with more than 30% of its rated capacity. The battery will be fully charges, but the charning current must not excced 30% of its rated capacity.

Installation control batteries

  1. Check that the battery is completely clean and that the terminals are free from corrosion.

  2. Check and note the temperature in the battery compartment.

  3. Check the terminal voltage of each battery before installation. If the difference between the batteries exceeds 0.5 V, the battery loop should be equalized in connection with installation. If any battery has a terminal voltage of less than 12V, this battery must be replaced with a new battery and reported to the supplier.

  4. Connect the battery and check the charging voltage. The charging voltage should be between 2.25 V - 2.27 V per cell = between 13.5 V - 13.62 V for a 12 V system and between 27.0 V - 27.24 V for a 24 V system.

Year-round inspection

  1. Check that the battery is completely clean and that the terminals are free from corrosion. If there is corrosion on the terminals: Check that the battery does not leak acid. Then clean the terminals and reconnect the battery. Then lubricate with battery terminal grease over the connected terminal.

  2. Check and note the temperature in the battery compartment.

  3. Check and note the average current.

  4. Check that all connections are securely fastened and that there is no gap in the connection.

  5. Check that the fan (if units have a fan) is working properly. Clean the fan if necessary.

  6. Check the charging voltage by measuring with a multimeter between the connection points + & amp; -. The charging voltage should be between 2.25-2.27 volts per cell = between 13.5-13.62V for a 12V system and between 27-27.24V for a 24V system.

  7. Turn off the rectifier and let the batteries rest for 10 - 15 minutes. Then measure the terminal voltage of each battery. After resting, the terminal voltage must be between 12.9 V - 13.5 V.

Information - Batteries purchased by Milleteknik

We count batteries as sellable and in good condition 14 months from the date of manufacture. Batteries are marked by the battery manufacturer and we aim for the time from the manufacturing date of the battery to the time a battery leaves us to be as short as possible. Then our customers get the best reliability. Milleteknik has carefully selected a battery supplier as there are large differences in quality and thus the lifespan of batteries. We sell three types of lead-acid batteries: 6+ Design life* - batteries with a service life in standby power of 2-3 years. 10+ Design life* - batteries with a service life in standby power of 5-6 years. 12-15+ Design life* - batteries with a service life in standby power of 6-8 years. *Design life refers to durability of a battery that has not been used. Batteries generate energy through a chemical process that never completely stops, even if the battery is not in use. When a battery is used, the chemical process increases and the life of the battery decreases. Design Life thus does not refer to a battery's lifespan. A battery's lifespan depends on a variety of factors, with use and heat being the main causes of shorter lifespan.
