Varta N60 Dynamic EFB · Start-Stop battery 60Ah 640A

Yes. The N60 is an EFB (Enhanced Flooded Battery): flooded lead-acid reinforced with plate 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.

Yes. It is a EFB battery of 60 Ah, designed for vehicles with Start-Stop. EFB batteries cover basic Start-Stop (no regenerative braking). It needs nothing to work, though on most modern cars registering it via OBD is advisable so the alternator adjusts its charging profile. 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.

For the detail, read our guide to replacing the car battery and, if in doubt, the owner's handbook or a main dealer. 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. 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 right), keeping the polarity; reconnect the positive (+) first and the negative (−) last. If the car has Start-Stop or BMS: a) the technology must match the original (AGM or EFB) or be higher, because a conventional battery would fail within months; b) undo the negative cable at its nut, leaving the IBS sensor in place; c) it is advisable to register the battery via OBD so the alternator applies the proper charging profile.

Estimated lifespan of the Varta N60: 4 to 6 years in basic Start-Stop car use. Treat it as an approximate guide, as every case is different. 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.

Measure your car's battery tray first; if the battery exceeds it by even a millimetre, the hold-down clamp may not close. Length × width × height: 242x175x190 mm (L2 case). Height is measured to the top of the terminals. Hold-down: B13.

The N60 has the positive on the right in a L2 case: that is its polarity. It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on.

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)). If our table and the car handbook disagree, go with what the manufacturer says. The compatibility list for the N60 runs to 346 verified vehicle versions.

A battery interchangeable with the Varta N60 must match it on dimensions (242×175×190 mm), polarity (positive on the right), capacity (60 Ah) and cranking current (640 A). Not just any technology will do: an EFB cannot be replaced with a conventional battery in Start-Stop cars. The "Equivalents" section further down lists the recommended alternatives.

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. Thicker grids plus carbon and polyethylene additives in the plates: that is what sets an EFB apart from a conventional flooded battery. The result is more cycles and more resistance to deep discharges, without reaching AGM level. 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 N60 is an EFB.

On most cars it is not strictly necessary: the alternator detects the new battery and adapts the charge by itself. It is advisable, though, to register it via OBD so the optimum profile applies from the first minute and the battery lasts as long as possible, especially on brands with sophisticated BMS (BMW, Mercedes, Audi, Volvo, Land Rover). To do it yourself: VCDS or Carista on VAG, Bimmercode on BMW, iCarsoft. At a workshop with an OBD scanner it takes minutes. Even if you do not register the Varta N60, the car will start correctly; the profile adjusts within a few days.
