Kronobat DP-70-AGM 12V 70Ah 760A is a battery for auxiliary services in motorhomes, caravans and campers. Powers the fridge, interior lighting, water pump and sockets while parked, with no need for campsite mains. Withstands daily discharges throughout the season.

The 12 V, 70 Ah Kronobat DP-70-AGM battery from the Dual Purpose AGM range with AGM technology is designed for motorhomes, caravans and campers that need power off-grid. Measuring 278 × 175 × 190 mm and the positive terminal on the right, it is the direct replacement for motorhomes and caravans fitted from the factory with a 70 Ah battery of this format.
In short: the Kronobat DP-70-AGM (70 Ah, 760 A, 278 × 175 × 190 mm, positive terminal on the right). Verified equivalent alternatives: Varta A7 and Exide EK720.
The Kronobat DP-70-AGM is designed for motorhomes, caravans and campers that need power off-grid: it powers fridge, lights, pump and chargers for several days off-grid. Its 70 Ah capacity sets the available autonomy. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 20.40 kg and 1.0 terminals.
Within the Kronobat catalogue, the Dual Purpose AGM series groups the references designed for this use. The DP-70-AGM is the 70 Ah model of that family, with the same performance as its siblings in other sizes.
AGM (Absorbent Glass Mat) technology seals the electrolyte in glass microfibre. The result is a maintenance-free battery that is highly vibration-resistant and able to withstand deep discharges that would ruin a classic lead-acid battery.
In terms of format, the Kronobat DP-70-AGM measures 278 × 175 × 190 mm (length × width × height) and weighs 20.40 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. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.
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. We guarantee that every Kronobat arrives new, charged and with the manufacturer's full warranty.
During months of storage, keep it charged with a mains charger or a small solar panel; a battery left discharged for weeks loses capacity permanently. Charge with a charger that has an AGM mode: it limits the voltage and protects the glass-fibre separators.
The Kronobat DP-70-AGM comes with the manufacturer's official warranty against manufacturing defects. Avoid repeated full discharges: they shorten its life and are not covered.
Same-day dispatch from our warehouse for in-stock orders placed before 6:00 pm: 24-48 working hours in mainland Spain and Portugal, 3 to 5 days in the islands and the rest of Europe. Returns are accepted for 14 days if the battery has not been used (free collection on the Iberian mainland). You will receive tracking by email.

Equivalences verified by our technical team: same dimensions, polarity, capacity and CCA. Official manufacturer warranty on every option.
Yes. The DP-70-AGM from Kronobat uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for caravans with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
In most caravans it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — with positive on the right match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On caravans with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
Expected lifespan of the Kronobat DP-70-AGM is 5 to 8 years in mild-climate caravan use with Start-Stop. In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
Dimensions (length × width × height) are 278×175×190 mm — also written as 278x175x190 mm and correspond to the European L3 case size — following the European DIN standard. Always measure the space in your caravan before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.
Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The DP-70-AGM typically fits a wide range of European vehicles thanks to its standard DIN case format.
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop caravans. See the "Equivalents" section to view recommended options at the same performance level.
