Frequently asked questions

Morgan Plus Eight 3.9 (188 hp, petrol, 1990-1995) takes a conventional 40 Ah, 330 A battery (187 × 127 × 227 mm), with the positive terminal on the right. Compatible batteries offer 40 Ah, 330 A (CCA), 12 V, case B19, conventional flooded technology. Browse the compatible battery list below.
The exact Ah rating for the Morgan Plus Eight 3.9 depends on the vehicle's original electrical consumers. Compatible batteries offer 40 Ah, 330 A (CCA), 12 V, case B19, conventional flooded technology. Use our finder for a precise recommendation.
To find the exact battery you need, you need to know the make, model, and engine. If your car has a Start-Stop system (the engine shuts off at traffic lights), you need an AGM or EFB battery. An AGM battery can only be replaced with another AGM battery. However, an EFB battery can be replaced with either another EFB or an AGM battery, as the latter is superior.
The standard battery is the conventional type. The EFB battery withstands start/stop cycles better. The AGM battery is the most durable and is mandatory in cars with Start-Stop and regenerative braking. Never replace an AGM battery with an EFB or standard battery.
Use the search tool by selecting your vehicle's make and model. Our system automatically filters compatible part numbers verified by our technicians. If you have any questions, contact us via WhatsApp.
All our batteries come with the legal guarantee provided by consumer law against manufacturing defects. If a battery has a manufacturing defect, it will be replaced at no cost to the user.
Under normal circumstances, batteries usually arrive within 1 to 2 days of ordering. However, there are some cases where delivery may take a little longer: peak seasons (Black Friday, Christmas, etc.), palletized shipments, occasional stock shortages, etc.
In mainland Spain and Portugal delivery takes 24 working hours if you order before 6:00 pm and the battery is in stock; for the Balearic Islands and other EU destinations allow 2 to 5 days. Batteries are shipped fully charged and ready to install.
