Boat battery replacement on site - fast and professional
When should a boat battery be replaced?
There are several ways you may notice that your batteries are due for replacement:
- Battery drains faster than normal
- Engine starts with difficulty or not at all
- You smell a foul odor coming from the battery box (H₂S gas). Beware, this is dangerous!
- Batteries get too hot while charging
Often this happens at an inconvenient time: during your vacation or day trip. By getting a checkup done early, you avoid downtime and frustration.
On-board battery replacement: our process
Our mobile battery replacement service works easily:
- Control on board
Our specialist will visit you and measure the current batteries. That way you will know exactly which batteries are still good and which ones need to be replaced. - Fast delivery from our own stock
Common starter and on-board batteries are standard in our service vans. Does the entire battery pack need to be replaced? Then we order it directly from our suppliers, at competitive rates. - Checking installation & connections
We install batteries safely and neatly. In the process, we also immediately check whether battery terminals, cables or fuses need replacing - and replace them immediately if necessary. - Checking charging voltage
Excessive charging voltage shortens the life of your battery and can even be dangerous. This is why we always check the charging system and adjust the charging voltage properly.
