Controller battery replacement

Controller batteries are the standby packs in the access-control power supply, not the coin cell in a fob. When they fail, doors can release, stay locked, or drop offline in a power cut depending on how the lock was specified.

About Controller Battery Replace

Controller batteries are the standby packs in the access-control power supply, not the coin cell in a fob. When they fail, doors can release, stay locked, or drop offline in a power cut depending on how the lock was specified.

We read the date code, measure the pack under the load the panel expects, and replace it when it is due or already swollen. We do not guess a remaining life from the label colour. The fire-release relay is checked after the swap so a battery change does not leave a maglock held on. Battery type follows the PSU, so we do not advertise a universal price. The visit is POA. Brands include Paxton, TDSi, CDVI, Vanderbilt and the rest of the access-control list. Tunstall nurse-call batteries are a different job.

  • ●Date code and a load check, not a cosmetic swap
  • ●Fire-release relay confirmed after the change
  • ●Correct pack for that PSU
  • ●POA — no battery price list

Controller Battery Replace FAQ

How often are standby batteries changed?+

Many packs are dated for a four-year service life. We change earlier if the test says the pack will not hold the doors.

Will the doors unlock while you work?+

We plan the isolation. Escape doors are not left unusable. The sequence is agreed before the PSU is opened.

Do you stock every brand of battery?+

We carry common 12 V packs and order the odd PSU-specific pack. The quote says which.
