Exide EL955 · Start-Stop battery 95Ah 800A EFB

Yes. The Exide EL955 uses EFB (Enhanced Flooded Battery) technology, that is, flooded lead-acid with plates reinforced by additives. It goes into cars with basic Start-Stop (no energy recovery when braking): more cycles than a conventional battery, fewer than an AGM, and cheaper than an equivalent AGM.

EFB batteries cover basic Start-Stop (no regenerative braking). The Exide EL955 is EFB, so yes, it is designed for Start-Stop cars. Basic Start-Stop: EFB. Start-Stop with regenerative braking: AGM, which withstands more cycles. Check the handbook for the technology the car manufacturer requires. Registering it via OBD is advisable on most modern cars (the alternator then applies the optimum profile), but it works from the start.

Our blog guide covers it in detail; if the owner's handbook describes a different procedure, follow the manufacturer. Allow 15-30 minutes and a 10 mm spanner. If the car keeps its battery in the boot or under a seat, it can take up to twice as long. The right order: engine off and key out; disconnect the negative (−) first, then the positive (+); release the hold-down clamp, lift out the old battery and seat the new one in the same position (positive on the left), keeping the polarity; reconnect the positive (+) first and the negative (−) last. Start-Stop or BMS specifics: do not remove the IBS sensor on the negative terminal (just loosen the cable nut); after the swap, register the battery via OBD so the alternator charges with the right profile; and never step down in technology: if the car had AGM or EFB, the new one must be the same or better, as a conventional battery lasts only a few months.

As a rough estimate, the Exide EL955 typically lasts 4 to 6 years in basic Start-Stop car use; it is a guide figure, not a guaranteed period. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance, as well as the type of car and whether it has Start-Stop.

The Exide EL955 takes up 306×173×222 mm (length, width and height, terminals included). Before buying, measure the space in your car: one extra millimetre can stop the hold-down clamp from closing.

Polarity of the Exide EL955: positive on the left. If your current battery has its positive on the other side, this one is not suitable without longer cables or a reconfigured system (short-circuit risk). Seen from the front, terminals towards you, the positive (+) is the post with the red ring.

For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). The car manufacturer's specifications always take priority over our tables.

Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the EL955, 95 Ah (800 A cranking). See the "Equivalents" section of this page for the recommended options at the same performance level. Mind the technology: in Start-Stop cars an EFB is not swapped for a conventional battery.

It is the verified Tudor equivalent for the EL955 tray. Compared with the EL955 it has the same Ah and cranking power. It costs 7,00 € more. Decide by price, brand preference and availability: both fit and crank the same.

Many basic Start-Stop systems (no regenerative braking) come with it from the factory, such as Renault Energy TCe, Peugeot/Citroën PureTech, Fiat MultiAir, Hyundai/Kia ISG and Ford EcoBoost. The EFB (Enhanced Flooded Battery) is a reinforced flooded battery: plates with carbon and polyethylene additives and thicker grids, giving it more cycles than a conventional one; for cycles and deep discharges it still sits below an AGM. Rule of thumb: car with an EFB from new, EFB (AGM is an optional, marginal upgrade); car with an AGM from new, AGM.

The alternator detects the new battery and adapts the charge automatically, so on most cars it is not compulsory. Even so, it is advisable to register it via OBD so charging is optimum from the first minute and the battery lasts longer, particularly on BMW, Mercedes, Audi, Volvo or Land Rover, with more sophisticated BMS. Any workshop with an OBD scanner does it in a few minutes; DIY, with VCDS or Carista (VAG group), Bimmercode (BMW) or iCarsoft. Even if you do not register the Exide EL955, the car will start correctly; the profile adjusts within a few days.
