# What to do if the house battery isn't holding a charge

## This article explains a basic test to complete on your house battery if it is not holding charge

There could be many reasons for this issue, so we recommend you do the following test and document what happens before calling our TrailLite service centre with the results. Without this test, it is tough to figure out the issue.

**Battery Test:**

- Firstly, note down your battery voltage.
- Plug your motorhome into mains power and leave it on charge for 8-12 hours. It’s best to do this overnight to test during the daylight hours.

- Ensure your mains charger is plugged in and working by either sighting the charger itself to see if display lights are on or by sighting the display in your motorhome to show the battery is charging.
- After 8-12 hours on charge, unplug from the mains and make note of the voltage.
- Continue to monitor and document the voltage during the day while you are using the motorhome – turning on lights, TV etc.
- If you see your voltage drop considerably within the first hour, this could be a sign that your batteries are damaged and need replacing.
- Please note that batteries do require replacing, and their recommended replacement schedule is noted on the battery or in your user manual.
- Once you have completed this test and you suspect there is an issue, please call our TrailLite service centre.

**Please Note:**

- Your warranty and maintenance booklet has a guide to batteries and looking after your battery. Please refer to this for more information.
