EFB Battery Replacement, Mobile Fitting
EFB battery replacement on your driveway across the West Midlands: the correct EFB battery for stop-start cars and light vans, fitted and coded where required.
EFB (Enhanced Flooded Battery) is the middle-ground between a standard flooded battery and an AGM, used on many entry-level stop-start cars and light commercial vans.
Fitting an EFB where the car needs an AGM will fail; fitting an AGM where an EFB is specified is fine but overkill. We fit the correct spec for each vehicle.

EFB battery fitting, specific questions
Q.What's the difference between EFB and AGM?
AGM handles higher cycling loads (premium and full stop-start); EFB is a lighter-duty version suited to entry-level stop-start. Fitting the wrong one fails early.
Q.Can I fit an AGM instead of EFB?
Yes, no harm done, just costs more than needed.
Q.Do you code EFBs to the BMS?
Yes, mandatory on Ford BMS cars, PSA group, and increasingly on other manufacturers.
Q.Can I use an EFB battery in a normal car?
Yes. An EFB can be fitted to a car that was built with a standard flooded battery, as long as the size, terminals and rating match. It simply has more cycling ability than that car needs.
Q.Which is the best EFB battery for my car?
The one that matches your vehicle's specification for size, capacity and cold cranking rating. We fit EFB batteries from the major brands and match the battery to your registration.
What we actually see on these jobs
- EFB is cheaper than AGM but not compatible with the highest-cycle stop-start systems.
- Ford and PSA (Peugeot/Citroen) need BMS coding on replacement, we handle it.
- Wrong spec fitting is the #1 reason we get called back, we always confirm before ordering the battery to the van.
What an EFB battery is for
An EFB battery is a strengthened version of a traditional flooded battery. Thicker plates and an additive layer help it handle the frequent stops and restarts of entry-level stop-start systems, and it recovers charge faster than a standard battery between short journeys. It sits between a standard flooded battery and an AGM in cycling ability.
EFB battery replacement is about matching the specification. The size, terminal layout, capacity and cold cranking rating all need to suit the car, and the battery management system usually needs to be told a new battery has been fitted. Fitting a standard battery where EFB is specified tends to end with stop-start switching off and the battery wearing out early.
EFB prices, brands and choosing the best EFB battery
EFB battery prices vary with case size and rating, which is why a figure quoted for one battery code, such as a 646, does not tell you what your car needs. Banner, Amaron and other brands all make EFB ranges, and the best EFB battery for a car is the one built to its specification rather than the one with the biggest numbers on the label.
We quote on the phone once the registration is confirmed, covering the battery and the fitting, and code the new battery where the car requires it.

General questions
Q.Do you code new batteries to the vehicle?
Yes, wherever the manufacturer requires it, BMW, Audi, VW, Mercedes, Ford, Vauxhall, Peugeot/Citroen. OBD-level coding included with every fit that needs it.
Q.Are you insured?
Yes, fully insured with public liability and goods-in-transit on every callout and every battery we fit.
Q.Can you help if I'm not with the car?
Sometimes, a driveway job with keys posted through the letterbox works. For car parks and depots we need someone at the vehicle for keys and payment.
In short
EFB fitting is about the right spec, not just a cheaper AGM. We fit what your car actually needs.
