Varta LA105 Professional Dual Purpose AGM 105Ah 950A 12V Battery

The Varta LA105 battery is the 12 V, 105 Ah model delivering 950 A of cold cranking power (EN) from Varta's Professional Dual Purpose AGM range, designed for motorhomes, boats and auxiliary power equipment. Measuring 394 × 175 × 190 mm and with the positive terminal on the right, it is the direct replacement for vehicles that leave the factory with a 105 Ah battery in this format.

In short: the Varta LA105 (105 Ah, 950 A, 394 × 175 × 190 mm, positive terminal on the right). Verified equivalent alternatives: Varta H15 and Tudor TK1050.

• Ideal for motorhomes, marine use and domestic power on board.
• Dual cycle: it both cranks the engine and powers auxiliary equipment.
• More endurance on board than a conventional starter battery.
• Tolerates deep discharges and repeated recharging without degrading.

Size and fitting of the Varta LA105

In terms of format, the Varta LA105 measures 394 × 175 × 190 mm (length × width × height) and weighs 29,4 kg. The positive terminal on the right determines which side the cables run to: it is the detail that causes the most buying mistakes, so it is worth checking before ordering. It uses a B13 hold-down and a type 1 terminal, the system that anchors it to the vehicle's battery tray. Checking the three dimensions and the terminal position before buying avoids the most common mistake when replacing a battery.

The Varta LA105 and the Professional Dual Purpose AGM range

The Professional Dual Purpose AGM range combines dual-purpose duty (starting + domestic supply) with AGM technology, which brings greater cycling endurance, zero maintenance and safety against spillage.

It is the demanding choice for motorhomes and boats that need to crank the engine and sustain a heavy equipment draw with maximum durability.

Unlike a pure starter battery, this range tolerates deep discharges and repeated recharging without degrading: exactly what a motorhome or a boat that draws power with the engine off needs. It therefore combines cranking and domestic duty in a single dual-cycle battery.

Why choose a Varta battery

Choosing Varta means going with the reference the car manufacturer itself signed off on in its day. Against own-brand batteries, the difference is not the purchase price but how many winters the battery lasts before leaving you stranded.

Behind Varta is Clarios, one of the largest manufacturers of starter batteries in the world and a supplier to the assembly lines of numerous car brands. That German engineering heritage translates into reliable starting year after year.

More than 100 manufacturing parameters are checked on every Varta battery before it leaves the plant, a level of rigour that explains why so many workshops and manufacturers trust the brand as their first-choice replacement.

Manufacturer's warranty

The Varta LA105 battery comes with the official manufacturer warranty.

Care and maintenance

In leisure applications, avoiding discharges below 50% of capacity multiplies the number of cycles the battery will deliver. A suitable charger and, where possible, a solar regulator keep it healthy through the seasons when it sees less use. To extend its life, recharge it as soon as possible after each discharge and never leave it flat over the winter. A trickle charger is the best investment for getting many cycles out of it.
