An added advantage of this model is that replacing the battery is a fairly straightforward process that may spare you from expensive service charges. The following is a comprehensive guide on how to replace an ADT alarm system battery with the easiest of methods.

Before You Begin

Before changing the ADT alarm battery, there are a few things you'll need to do to prepare: Check the existing battery – The control panel cover should be opened and there is a battery within. If it is filled with water or the tote is swollen or leaking, then it will be necessary to replace it as soon as possible. Avoid contacting anything that may be leaking such as acids, oil, or any other substance.

  • Purchase replacement - Rechargeable batteries from a reputable store that deals with alarm systems will have to be bought so that you can replace the ones that have been drained. Typically affordable SLA batteries are 12V 4Ah or 7Ah, and there are many different brands available. Buy from an electronics, hardware, or home security store, if possible.
  • Change battery – It is advisable to change the battery of the ADT system, and when doing this, the monitoring company will send the authorities if they sense movement during the replacement process.
  • Prepare equipment - Keep close by basic home improvement tools such as a screwdriver, pliers, rubber gloves, and safety glasses. These will help in the safe handling of batteries during their removal and installation.
  • Practice safety – Batteries consist of lead and acid both hazardous materials, and it is important to know how to handle them properly to prevent personal injuries or polluting the environment.

Step-by-Step Battery Replacement

Once you have all the prep work done, changing the ADT alarm battery involves just a few simple steps: 

  1. Deactivate the system – If you are using a control panel, look for a switch and set it to turn off the system. This prevents false alarms.
  2. Lift the top – this is the most obvious part of the process, you need to carefully unscrew the top part of the control panel, which can be made of metal or plastic. Set it carefully aside.
  3. Remove old battery – Locate the cables connecting the old battery to identify the connection to remove. To disconnect it, pull the connector gently away from the clipping.
  4. Take out the old battery – There can be a clip or a band that is used to secure the battery in position. Take your little screwdriver and very gently unscrew this part and then slide out the old battery. Put it in a safe place where it will not get mixed with other waste and just wait for the best opportunity to recycle it.
  5. Replace the battery with a new one – The new battery is placed at the previous position of the old battery with the terminal ends facing upwards. Secure it with the battery strap or bracket. Mount the positive post of the battery to the ‘+’ terminal of the alternator.
  6. Connect the new battery – Now join the connector wire to the terminals of the new battery. It should lock and feel solid and heavy to the point that it should make a clicking sound when properly locked in place.
  7. After that, tighten the screws and remove it – This is the final step and involves replacing the control panel cover and tightening the screws to ensure that it fits properly. Reset your ADT alarm system to active and activate your sensors to check if the battery is charging the system as it should.
  8. Recycle old battery – This is because with the new battery identified and your system now working on it, the old battery should be properly disposed of. Lead-acid batteries should not be disposed of in the same way as other household items, in a trash can. Instead, seek out the nearest battery recycling facility or hazardous waste drop-off center.

Additional Tips

Here are some extra tips to help the battery-changing process go smoothly: 

  • To avoid accidents use gloves and goggles when handling batteries for safety reasons.
  • Batteries must not be placed on surfaces that will cause a short circuit as a result of conductivity.
  • After installing the new battery, make sure that all the wires and connectors are properly connected with no interferences.
  • If you still hear your alarms when using the new battery, then you need to contact ADT support to address wiring or connectivity problems.
  • Using a permanent marker, write the install date for the new battery so that you can be in a position to know when the battery is best suited for replacement.
  • Create an annual calendar to replace batteries, so that if checks on battery voltage have to be done, this will have to be done every year.

Each of the above steps, as well as the necessary safety measures adopted, enables you to perform this vital security system maintenance on your own.
