Automower Battery Replacement 315x, 315, 310

This quick guide shows you step by step how to change the battery in a 315x, 315 or 310 Husqvarna Automower with a  Serial number up to 2005XXXXX.

1.You will need an area with good lighting and some type of workbench to work on. Prepare your Automower for work by brushing off all loose debris. 

2. You will need a Torx T20 screwdriver or T20 bit for a drill. If you do use a drill to screw/unscrew you need to make sure you only use a very slow speed otherwise you can strip the threads in the chassis. If you want to do the job properly a torque wrench should also be used. Of course you will also need a new wheel motor to fit.

If your Automower has a Up to Serial number 2005XXXXX then you need this  315,315x,310 replacement battery.  

3. Make sure you have switched off the Automower with the switch on the underbody and towards the back of the main body.

4.You need to dismantle the body. underneath the machine and towards the front on you will see rubber grommets. You need to pull these out.

Be careful when doing this as each rubber grommet is attached to a cable that you need to unclip. The cables should come out around 5cm. 

5. Next step is to remove the automowers top chassis from the main body. To do this we suggest pressing your hand onto the centre of the automower where the keypad is located. With your other hand you pull up on the corners of chassis, this should pop off. You will find a lot of dirt and debris underneath and this will need to be cleaned off before you can split the body. Its very important not to let any dirt inside the main body of the automower.

6. Unscrew all of the torx T20 screws shown by each arrow. Once completed you also need to remove the warranty seal located on the side of the body.

7. The body can split now and you need to lift slowly from the front and you will see that there is a HMI cable attaching the sections together. unclip this and you can remove the top half of the body and place it out of the way.

 8. Follow the from the battery to the main circuit board. discount the wires and replace with the new battery.

9.  You need to reverse all of the steps to assemble your machine back together.
