How to replace battery on Automower 105,305 or 308
In this guide we will show you step-by-step how to change the battery of your Husqvarna Automower 105. The same procedure applies to Automower 305 and 308.

How often do I have to change my battery?
Normally a genuine Husqvarna battery will last for 5-6 seasons. This also depends on how big your lawn is and how many hours per day that your Automower has to cut. An indication of when the battery needs to be changed is when your Automower returns to the charging base more frequently or when it suddenly stops in the middle of the lawn with an error message 'Empty battery'.

On the bottom of this page you will find the correct OEM spare parts that we use for this replacement.

Required tools: Torx screwdriver T20.

Step 1: Turn your Automower upside-down. Unscrew the four marked Torx-screws as shown in the image.	Step 2: Remove the lid.
Step 3: Take out the old battery from its holder.	Step 4: Install the new battery and make sure that it is connected properly.
Step 5: Place the lid over the battery and tighten the four screws holding the lid.

When this procedure is done, make sure to fully charge the Automower before letting it go back to work.
