Kronobat PE-60-EFB Premium EFB · Start-Stop battery 60Ah 640A

Yes. The PE-60-EFB is an EFB (Enhanced Flooded Battery): flooded lead-acid reinforced with plate additives. It withstands more cycles than a conventional battery but fewer than an AGM, and it is fitted to cars with basic Start-Stop, without regenerative braking. It is more affordable than an equivalent AGM.

Yes, the EFB technology of the PE-60-EFB is built for Start-Stop. EFB batteries cover basic Start-Stop (no regenerative braking). Registering it via OBD is advisable on most modern cars (the alternator then applies the optimum profile), but it works from the start. As a rule: EFB for basic Start-Stop, AGM when there is also regenerative braking (more cycles); in any case, what the car manufacturer specifies.

Tool: a 10 mm spanner. Time: 15-30 minutes on almost every car, and up to double if the battery is not under the bonnet but in the boot or under a seat. With Start-Stop there are three more points: the negative terminal usually carries a battery sensor (IBS), so undo the cable at the terminal nut without removing the sensor; register the battery via OBD so the alternator applies the correct charging profile; and fit the same technology as the original (AGM or EFB) or higher, because a conventional battery wears out within months. What matters most is the terminal order: removing, negative (−) before positive (+); refitting, positive (+) before negative (−). In between, with the engine off and the key out, release the clamp and fit the new battery the same way round as the original, positive on the right (polarity). For the detail, read our guide to replacing the car battery and, if in doubt, the owner's handbook or a main dealer.

There is no exact figure: for a battery such as the Kronobat PE-60-EFB (EFB), a reasonable guide is 4 to 6 years in basic Start-Stop car use. Actual lifespan varies with climate (cold starts, heat evaporating the electrolyte), with usage and short journeys, with the condition of the alternator and charging system, with power draw while parked and with maintenance; the type of car and Start-Stop also count.

Check the room available in your car, because a single millimetre too much can stop the clamp from closing. Its dimensions are 242×175×190 mm, also written 242x175x190 mm; the height already includes the terminals. In European terms it is a L2 case.

It has the positive on the right (polarity). 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). Put it in front of you, terminals towards you: the post with the red ring and the + sign is the positive.

The quickest way is to enter your number plate in the finder: DGT/DVLA/KBA detect model and engine. You can also look at the "Compatible vehicles" tab, verified by our technical team, or send us make, model, engine and year on WhatsApp; we answer during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). Always cross-check with what the car manufacturer states in the owner's handbook.

The "Equivalents" section of this page gathers the recommended options with equivalent performance; remember that in Start-Stop cars an EFB should not be replaced with a conventional battery. A battery interchangeable with the Kronobat PE-60-EFB must match it on dimensions (242×175×190 mm), polarity (positive on the right), capacity (60 Ah) and cranking current (640 A).

It is the AGM of the same case: more cold cranking, faster charging and far more resistance to cycling and heat than the PE-60-EFB. Compared with the PE-60-EFB it has 40 A of cold cranking more. It costs 18,90 € more. Mandatory if the original was AGM; in a car without Start-Stop the PE-60-EFB does the job and AGM is a bonus in cranking and durability, not a necessity.

It has the same dimensions, voltage and technology as the PE-60-EFB, although it is not a manufacturer-approved equivalent. Compared with the PE-60-EFB it has the same Ah and cranking power. It costs 8,60 € more. Check the positive terminal side and the original capacity before ordering; otherwise it is a straight swap.

EFB from the factory? Stay with EFB; AGM is optional and only a marginal improvement. AGM from the factory? Then fit an AGM, because an EFB would fall short. This PE-60-EFB is an EFB. It is still flooded lead-acid, but an EFB reinforces the plates with carbon and polyethylene and uses thicker grids. That gives it more cycles than a conventional battery and deeper discharge tolerance, though less than an AGM. Its place is basic Start-Stop without regenerative braking, fitted from new in, for example, Renault Energy TCe, Peugeot/Citroën PureTech, Fiat MultiAir, Hyundai/Kia ISG or Ford EcoBoost.

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 Kronobat PE-60-EFB, the car will start correctly; the profile adjusts within a few days.
