The benefits of Mobile Car Battery Replacement Telford

AGM (Absorbent Glass Mat) batteries are a popular choice for stop-start systems in modern vehicles. These batteries offer several advantages over traditional lead-acid batteries, particularly for cars equipped with stop-start technology. Here are the key benefits of AGM stop-start batteries:

Benefits of AGM Stop-Start Batteries:

  1. Enhanced Cycle Life:

    • AGM batteries have a significantly longer cycle life compared to conventional lead-acid batteries. This makes them well-suited for stop-start systems, which require the battery to endure frequent charging and discharging cycles.
  2. Improved Charge Acceptance:

    • AGM batteries can accept charge quickly, which is crucial in stop-start systems. They can recharge faster during short periods of driving, ensuring that the battery is always ready to provide the necessary power.
  3. Maintenance-Free:

    • AGM batteries are sealed and maintenance-free, meaning there is no need to add water or perform regular upkeep. This reduces the hassle for vehicle owners and ensures consistent performance.
  4. Enhanced Performance in Extreme Conditions:

    • AGM batteries perform better in extreme temperatures, both hot and cold, compared to traditional batteries. They are less likely to suffer from reduced performance or failure in harsh weather conditions.
  5. Superior Vibration Resistance:

    • The design of AGM batteries includes tightly packed plates and an absorbent glass mat separator, making them more resistant to vibrations and shocks. This durability is beneficial for vehicles that are driven on rough roads or off-road.
  6. Reduced Risk of Spills and Leaks:

    • AGM batteries are completely sealed, eliminating the risk of acid spills and leaks. This makes them safer for both the vehicle and the environment.
  7. Lower Self-Discharge Rate:

    • AGM batteries have a lower self-discharge rate compared to traditional lead-acid batteries. This means they retain their charge longer when the vehicle is not in use, which is particularly useful for cars that are not driven frequently.
  8. Support for Advanced Electrical Systems:

    • Modern vehicles with stop-start technology often come with numerous electronic components and accessories. AGM batteries provide stable and reliable power, supporting the vehicle’s electrical system effectively.
  9. Environmental Benefits:

    • AGM batteries are more environmentally friendly due to their longer lifespan and reduced need for replacement. This leads to fewer batteries being disposed of and less environmental impact.


AGM stop-start batteries offer several advantages, including a longer cycle life, better performance in extreme conditions, faster charging, and maintenance-free operation. These benefits make them particularly suitable for vehicles with stop-start systems, enhancing overall efficiency, reliability, and durability. When choosing a battery for a stop-start vehicle, AGM batteries are often the recommended option due to these superior characteristics.

How Mobile Car Battery Replacement Telford


Determining whether you need a jumpstart or a new battery for your mobile (presumably a car) involves a few steps to diagnose the issue. Here’s what you can do to assess the situation:

Step 1: Check for Signs of Battery Issues

  1. Dim Lights: When you turn on your car, are the headlights dim? This can indicate a weak battery.
  2. Slow Crank: Does the engine crank slowly when you try to start the car?
  3. Electrical Issues: Are there issues with electrical components, such as the radio or dashboard lights?

Step 2: Attempt a Jumpstart

  1. Safety First: Ensure both vehicles are off and the keys are removed.
  2. Connect Cables: Attach the red (positive) cable to the positive terminal of the dead battery and the other red end to the positive terminal of the good battery. Attach the black (negative) cable to the negative terminal of the good battery and the other black end to an unpainted metal surface on the engine block or chassis of the dead car.
  3. Start the Working Car: Let it run for a few minutes.
  4. Start the Dead Car: Attempt to start the car with the dead battery.

Step 3: Evaluate After Jumpstart

  1. Successful Start: If the car starts, let it run for at least 20 minutes to charge the battery. If the car dies shortly after, the battery may not hold a charge.
  2. No Start: If the car does not start, the battery may be completely dead, or there may be another issue.

Step 4: Consider Battery Replacement

  1. Age of Battery: Car batteries typically last 3-5 years. If your battery is older, it may be time for a replacement.
  2. Frequent Jumpstarts Needed: If you frequently need to jumpstart your car, it’s a strong indicator that you need a new battery.
  3. Battery Test: Many auto parts stores offer free battery testing. They can check if your battery is holding a charge properly.


  • Jumpstart: Try a jumpstart first if your battery is relatively new and you haven’t had frequent issues.
  • New Battery: If the battery is old, or if a jumpstart fails to keep the car running, you likely need a new battery.

If you’re still unsure, visiting a professional mechanic for a thorough diagnosis would be a good idea.
