Vehicles compatible with the Optima YTS-2.7J

The Optima YTS-2.7J is compatible with more than 9 vehicles: it is fitted as original equipment or as a replacement by brands such as Toyota and Lexus. It is a go-to option when you need a battery for a Toyota, Lexus or other models that use this same format. It is checked against 2 original-equipment references from different manufacturers.

The Optima YTS-2.7J: Yellow Top range and spiral-cell AGM technology

Within the Optima catalogue, the Yellow Top series groups the references designed for this use. The YTS-2.7J is the 38 Ah model of that family, with the same performance as its siblings in other sizes.

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.

Dimensions, polarity and mounting

In terms of format, the Optima YTS-2.7J measures 237 × 129 × 201 mm (length × width × height) and weighs 12.40 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 3 terminals, the system that anchors and connects it in the vehicle. Before replacing it, measure your current battery tray: if all three dimensions and the terminal positions match, the swap is direct and needs no adapters.

Why choose Optima batteries

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.

Care and maintenance

Charge with a voltage-controlled AGM charger; a fully discharged pure-lead battery may need a specific charger to recover. 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.

Official warranty

The Optima YTS-2.7J comes with the manufacturer's official warranty against manufacturing defects. Avoid repeated full discharges: they shorten its life and are not covered.
