Service Overview
Mobile car battery replacement service
What This Service Is
I regularly attend vehicles where a jump-start is no longer enough because the battery has reached the end of its chemical life. I provide a complete "Supply and Fit" solution at your home, workplace, or the roadside.
We provide a comprehensive mobile battery replacement service across Watford and Hertfordshire. We don't just "drop in" a battery; we source the exact manufacturer-spec unit for your vehicle and use diagnostic equipment to register the new battery to your car's power management system.
How the car battery replacement service works
1. Initial battery and system assessment.
We check the battery condition and look for signs of electrical or charging faults.
2. Safe jump start procedure
Professional equipment is used to protect modern vehicle electronics.
3. Charging system check
Once running, the alternator and battery performance are observed.
4. Clear advice before you drive away
You’ll be advised whether the battery is likely to hold charge or needs replacing.
Common Causes of a Dead Car Battery
Some of the most common flat battery causes:
Short or infrequent journeys
Cold weather reducing battery capacity
Electrical systems left on
Parasitic battery drain
Ageing or worn batteries
Alternator or charging issues
If the battery continues to go flat, a jump start may only be a short-term solution.
