# VARTA Professional Dual Purpose EFB Batteries > VARTA Professional Dual Purpose EFB Starting and Service Batteries for Marine and Motorhome. Reinforced electrolyte and good price-cycle ratio. **Category:** [Start](https://baterias.com/gb/beginning) → [Batteries](https://baterias.com/gb/batteries) → [VARTA batteries](https://baterias.com/gb/batteries-varta) - **Canonical URL**: https://baterias.com/gb/varta-professional-dual-purpose-efb-batteries - **Language**: en-GB ## Description Dual Purpose EFB covers the same dual function of starting and service as the AGM range, with reinforced electrolyte and a more contained price. ## Technology The carbon additive and polyester separator multiply the cycling resistance compared to a conventional starting battery, maintaining the current needed to start the engine. It is an intermediate solution: more cycles than a Starter and lower cost than an AGM, suitable when onboard consumption is regular but not intensive. ## Applications - Recreational boats with moderate consumption - Holiday motorhomes - Mixed installations with a tight budget - Replacement of a starting battery that frequently discharges ## The range in figures References 7 Capacity 60 – 240 Ah Cold cranking 640 – 1200 A (EN) Voltage 12 V Technology EFB ## How to choose If you notice that your starting battery runs out of charge after a weekend anchored, the problem is not the capacity but the technology: you need a battery prepared for cycling, and this range is the first step. ## Naming and equivalences Professional Dual Purpose EFB keeps its designation. It is the first step of the combined starting and service batteries, below the AGM version. ## Frequently asked questions ### When to choose EFB instead of AGM? When on-board consumption is regular but not intensive: weekend navigation, holiday caravan. If consumption is daily and prolonged, AGM or lithium compensates. ### My starting battery discharges after a weekend anchored, what do I need? The problem is usually not the capacity but the technology: a starting battery is not made for cycling. You need a battery prepared for repeated discharges, and this range is the first step. ### Does it require maintenance? It is a reinforced liquid electrolyte battery; it is advisable to check the level according to the manufacturer's instructions and keep it charged during periods of inactivity. ### Is it also suitable for caravan? Yes. It is a common application when using a single battery to start the engine and power the cell installation. ## VARTA Professional Dual Purpose EFB: reinforced dual purpose The **Dual Purpose EFB** combines starting and house duty just like the Dual Purpose SLI, but with a reinforced glass-fibre mesh on the positive plate that handles far more cold-start and repeated partial-discharge cycles. It's the technology VARTA reserves for **motorhomes with Start-Stop** and leisure vehicles with heavier onboard power demands (heating, compressor fridges, home automation). ### VARTA Professional Dual Purpose EFB models - **LFD90 EFB** (90 Ah): mid motorhome with Start-Stop. - **LFD140 EFB** (140 Ah): large motorhome. - **LFD160 EFB** (160 Ah): premium motorhome or RV with more electrical equipment. ### How to choose your VARTA Professional Dual Purpose EFB First check whether your motorhome manufacturer requires EFB because of the Start-Stop system, then match the capacity (Ah) to your onboard power use. Use our [battery comparison tool](/gb/comparator) to compare LFD90 EFB, LFD140 EFB and LFD160 EFB before deciding. ## Frequently asked questions about VARTA Professional Dual Purpose EFB ### **Is EFB mandatory if my motorhome has Start-Stop?** It's what VARTA recommends: a conventional SLI degrades much sooner under repeated start-stop cycles, while EFB is built to withstand them. ### **What's the difference between Dual Purpose EFB and Dual Purpose AGM?** EFB is the middle option: more cycle-resistant than conventional SLI but more affordable than AGM, which offers even more cycles and mounts at any angle. ### **Can it power onboard equipment with the engine off?** Yes, like the whole Dual Purpose range, it combines cranking and onboard load duty in one battery. ### **How does it last compared with a conventional SLI?** Under the same usage pattern, EFB withstands considerably more start-stop and partial-discharge cycles before losing capacity, meaning more years of service in Start-Stop motorhomes.
