What the Optima YTS-2.1 is for

With 55 Ah, the Optima YTS-2.1 is the habitation battery for motorhomes, caravans and campers that need power off-grid. It recharges from the alternator, a solar panel or a mains charger. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 8.90 kg and 1 terminals.

Will it fit your current battery tray?

The Optima YTS-2.1 is made in the 252 × 90 × 185 mm format and weighs 8.90 kg. The positive terminal on the left 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 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.

The Optima YTS-2.1: Yellow Top range and spiral-cell AGM technology

The YTS-2.1 is part of the Optima Yellow Top range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.

Spiral AGM construction winds the plates into cylindrical pure-lead cells: maximum active surface, extreme vibration resistance and cranking current far above a battery of the same size.

Optima: the maker behind the YTS-2.1

Optima makes spiral-cell (SpiralCell) AGM batteries with pure lead: maximum vibration resistance, very powerful cranking and a durability recognised in 4x4, motorsport, marine and car audio. We guarantee that every Optima arrives new, charged and with the manufacturer's full warranty.

Warranty and coverage

The Optima YTS-2.1 comes with the manufacturer's official warranty against manufacturing defects. Avoid repeated full discharges: they shorten its life and are not covered.

Usage and maintenance tips

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. Avoid routinely discharging the leisure battery below 50% and recharge it fully after every trip.
