### What the Kronobat PE-70-EFB is for

The Kronobat PE-70-EFB is designed for cars with Start-Stop, regenerative braking and heavy electrical loads. If your car was fitted with an AGM or EFB battery, always replace it with the same technology: a conventional model would degrade within months. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 18.90 kg and 1.0 terminals.

### Dimensions, polarity and mounting

The Kronobat PE-70-EFB is made in the 278 × 175 × 190 mm format and weighs 18.90 kg. The positive terminal on the right decides which side the cables end up on: it is the detail that causes most buying mistakes, so check it before ordering. It uses 1.0 terminals, the system that anchors and connects it in the vehicle. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

### What Kronobat does differently

With Kronobat we offer an own-brand alternative without compromising on quality: European manufacturing, original-equipment controls and the direct backing of baterias.com for warranty and advice. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.

### The Kronobat PE-70-EFB: Premium EFB range and EFB technology

Within the Kronobat catalogue, the **Premium EFB** series groups the references designed for this use. The PE-70-EFB is the 70 Ah model of that family, with the same performance as its siblings in other sizes.
EFB (Enhanced Flooded Battery) technology reinforces the conventional lead-acid battery with a polyester separator and carbon additives in the plates. It withstands many more start cycles and partial discharges, making it ideal for basic Start-Stop and intensive use.

### Care and maintenance

Do not mix technologies: a conventional battery in a Start-Stop car degrades within months. If the vehicle only does very short trips, a periodic maintenance charge with an AGM/EFB-compatible charger greatly extends its life.

### Manufacturer's warranty

The Kronobat PE-70-EFB comes with the **manufacturer's official warranty**. To keep it valid, always fit the same technology as the original battery (AGM or EFB) and register the replacement if your vehicle requires it.

### Delivery times and returns

Order **before 6:00 pm** with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have **14 days** to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

## Frequently asked questions

### Is this battery EFB? When is it used?

Yes. The PE-70-EFB is an EFB (Enhanced Flooded Battery): flooded lead-acid reinforced with plate additives. More affordable than an equivalent AGM and with more cycles than a conventional battery (though fewer than AGM), it is what cars with basic Start-Stop use, without regenerative braking.

### Is the Kronobat PE-70-EFB battery suitable for Start-Stop?

Yes: being EFB, the Kronobat PE-70-EFB is designed for Start-Stop cars. EFB batteries cover basic Start-Stop (no regenerative braking). Once fitted it is ready to go; registering it via OBD, advisable on most modern models, lets the alternator charge with the optimum 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.

### How is the Kronobat PE-70-EFB battery fitted in a Start-Stop car?

With a 10 mm spanner, swapping in the Kronobat PE-70-EFB takes 15 to 30 minutes on most cars; if the battery sits in the boot or under a seat, allow up to twice as long. With the engine stopped and the key removed, always start with the negative (−) terminal, then the positive (+). Free the clamp, swap the battery without turning it round (this one has positive on the right) so the polarity stays the same, and reconnect in reverse: positive (+) first, negative (−) last. On cars with Start-Stop or BMS, registering the battery via OBD makes the alternator charge with the correct profile. Mind the IBS sensor on the negative terminal too: loosen the cable nut, not the sensor. And the replacement must be the same technology (AGM or EFB) or higher: a conventional battery fails within months. For the detail, read our guide to replacing the car battery and, if in doubt, the owner's handbook or a main dealer.

### How long does the Kronobat PE-70-EFB battery last?

As a guide, you can expect the Kronobat PE-70-EFB to last 4 to 6 years in basic Start-Stop car use, although the real figure may be higher or lower. It can vary considerably with usage (short or long journeys), temperature, the condition of the alternator and charging system, power drawn with the engine off and maintenance, plus the car itself and Start-Stop. Cold demands more at every start and intense heat evaporates the electrolyte.

### What are the dimensions of the Kronobat PE-70-EFB battery?

Measure the battery tray before ordering: a one-millimetre difference is enough for the hold-down clamp not to close. It measures 278×175×190 mm in length × width × height, with the terminals included in the height; that is the European L3 case size.

### On which side is the positive of the PE-70-EFB model?

On the Kronobat PE-70-EFB, the polarity is positive on the right. To check, stand the battery in front of you with the terminals nearest you: the positive (+) is the one with the red ring. A change of polarity from the original means longer cables or a reconfigured system and can cause a short circuit: check it before ordering.

### Will the Kronobat PE-70-EFB battery fit my car?

Not sure? Try your number plate in the finder (DGT/DVLA/KBA detect model and engine) or the "Compatible vehicles" tab, checked by our technical team; if your car is not there, send us make, model, engine and year on WhatsApp and we will reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). In every case, the car manufacturer's specifications (owner's handbook) take precedence.

### Which batteries are equivalent to the Kronobat PE-70-EFB?

A battery interchangeable with the Kronobat PE-70-EFB must match it on dimensions (278×175×190 mm), polarity (positive on the right), capacity (70 Ah) and cranking current (760 A). 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.

### Kronobat PE-70-EFB or Kronobat EV-70-AGM: which one to choose?

A technology step up: sealed AGM, with stronger cranking and a noticeably longer life than the PE-70-EFB when the car draws a lot of power. Compared with the PE-70-EFB it has the same Ah and cranking power. It costs 9,20 € more. Choose it if your car required it from the factory or if you want the longest-lasting battery for this size; for normal use without Start-Stop, the PE-70-EFB is plenty.

### Kronobat PE-70-EFB or Varta A7: which one to choose?

The AGM of this size: what cars with Start-Stop and regenerative braking fit from the factory, and a real durability upgrade over the PE-70-EFB. Compared with the PE-70-EFB it has the same Ah and cranking power. It costs 39,55 € more. Essential if your car has Start-Stop, regenerative braking or came with AGM; without those systems it is an upgrade you do not need to pay for.

### What exactly is an EFB battery like the Kronobat PE-70-EFB?

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-70-EFB is an EFB. An EFB (Enhanced Flooded Battery) is flooded lead-acid, but reinforced: carbon and polyethylene additives in the plates and thicker grids. It handles more cycles than a conventional battery and copes better with deep discharges, though less well 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.

### Do I need to register the Kronobat PE-70-EFB on the car after installation?

It is not strictly necessary on most cars, because the alternator detects the change and adapts the charge. The advisable step is to register it via OBD: the charging profile is optimum from the first minute and the battery lasts longer, especially on brands with sophisticated BMS (BMW, Mercedes, Audi, Volvo, Land Rover). Any garage with an OBD scanner can do it in a few minutes. If you prefer to do it yourself: VCDS / Carista (VAG), Bimmercode (BMW) or iCarsoft. Even if you do not register the Kronobat PE-70-EFB, the car will start correctly; the profile adjusts within a few days.
