I’ve received the message Maximum battery age reached. Should I replace it right now?

Yes, the dialler’s battery is due for replacement. 

Good to know: the rechargeable LiFePO4 battery (LFR18650-2S | 6.4V/1500mAh | 9.6WH) supplied with the alarm dialler at the time of purchase has a service life of 3 years. The dialler indicates when the battery needs to be replaced via the message Maximum battery age reached. The battery is then due for replacement. The repeat delay after accepting this alarm is 30 days.

This is resolved as follows

It is quite easy to replace the battery yourself.

See Replace battery for further explanation.

Note: only use the battery supplied by Adésys for the Octalarm alarm diallers (A-Batt-6.4V)! Developed by Adésys, it is fully approved and has a chip which it uses to communicate its status. Order the battery from your installer or via our webshop: (www.adesys.nl|Products|Accessories).
