Can I use the Deep Cycle AGM to crank the engine?

That's not its job: its thick plates prioritise cycling, not cranking current. For that you need a separate VARTA Professional Starter or Dual Purpose battery.

How many discharges can it take without losing lifespan?

It tolerates repeated 50-80% discharges of its capacity without premature degradation, well beyond what a starting SLI can handle.

Is it compatible with solar panels?

Yes, it's the usual technology as the house bank in motorhome or caravan solar installations, provided the regulator's charge voltage is respected.

What's the difference versus the Dual Purpose AGM?

The Dual Purpose AGM combines starting and house duty in one battery; the Deep Cycle AGM is optimised purely for house use, with greater deep-discharge tolerance when cranking is already covered by another bank.

VARTA Professional Deep Cycle AGM: house duty only, deep cycling

Unlike the Dual Purpose, the Deep Cycle AGM is not built to crank an engine: its whole internal construction prioritises cycling, with thicker plates that withstand repeated 50-80% discharges without prematurely losing capacity. It's the go-to house battery when the starting bank runs separately, typical in large motorhomes, caravans with solar panels and boats with split electrical systems.

VARTA Professional Deep Cycle AGM models

LAD60 (60 Ah): small caravan.
LAD90 (90 Ah): mid motorhome.
LAD115 (115 Ah): large motorhome or mid-size boat.
LAD230 (230 Ah): premium motorhome or large boat.

How to choose your VARTA Professional Deep Cycle AGM

Work out your installation's daily consumption (fridge, LED lighting, water pump, solar charge controller) and add a safety margin before choosing between LAD60, LAD90, LAD115 and LAD230. Compare them in our battery comparison tool and confirm engine cranking is covered by a separate starting or dual-purpose battery.
