Leisure battery Optima YTR-2.7J Yellow Top 38Ah 460A 12V
The Optima YTR-2.7J with spiral-cell AGM technology stores 38 Ah at 12 V: autonomy for motorhomes, caravans and campers that need power off-grid. It measures 237 × 129 × 201 mm and the positive terminal on the right, the format sought by anyone replacing a 38 Ah battery in motorhomes and caravans.
- Power for fridge, lighting, water pump and USB off-grid.
- Spiral cells: maximum vibration resistance and very powerful cranking.
- Low self-discharge during months of storage.
- Sealed and gas-free: suitable for installation inside the living area.
Will it fit your current battery tray?
It has external dimensions of 237 × 129 × 201 mm and weighs 12.40 kg. The positive terminal on the right 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.
What the Optima YTR-2.7J is for
With 38 Ah, the Optima YTR-2.7J 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 12.40 kg and 3 terminals.
The Optima YTR-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 YTR-2.7J is the 38 Ah model of that family, with the same performance as its siblings in other sizes.
In a spiral-cell battery the electrolyte is absorbed and the plates are wound under pressure. That lets it deliver very high current peaks, recharge quickly and be mounted in any position.
Why choose Optima batteries
The Optima Red, Yellow and Blue Top are references for high-performance starting, deep cycling and marine use respectively, all with the characteristic six spiral-cell design. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
Warranty and coverage
The Optima YTR-2.7J comes with the manufacturer's official warranty against manufacturing defects. Avoid repeated full discharges: they shorten its life and are not covered.
How to make it last longer
Avoid routinely discharging the leisure battery below 50% and recharge it fully after every trip. 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.
Delivery times and returns
Orders placed before 6:00 pm with the battery in stock ship the same day. Delivery in mainland Spain and Portugal takes 24-48 working hours; for the Balearic Islands and the rest of the European Union allow 3 to 5 working days. You have 14 days to return an unused battery; in mainland Spain and Portugal collection is free. We email you the tracking number as soon as the parcel ships.

Frequently asked questions
Is the Optima YTR-2.7J an AGM battery and what are the benefits of AGM?
Yes. The YTR-2.7J from Optima uses AGM (Absorbent Glass Mat) technology: a sealed lead-acid battery where the electrolyte is absorbed in a glass-fibre mat. It withstands more charge/discharge cycles than a conventional one, handles heat better and is the required technology for caravans with advanced Start-Stop and regenerative braking. Expected lifespan: 5-8 years under normal conditions.
How much energy does this battery give a caravan?
It stores about 456 Wh. To make it last, it should not be discharged below half, so you have about 228 Wh usable: for example, an average load of 50 W for about 5 hours.
Can it be charged with solar panels?
Yes, with a charge controller (PWM or MPPT) set for AGM. It can also be charged by the vehicle alternator (ideally with a DC-DC charger) and by the 230 V charger when you are on hook-up at the campsite.
What size is this battery?
Dimensions (length × width × height) are 237×129×227 mm — also written as 237x129x227 mm — following the European DIN standard. Always measure the space in your caravan before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Which side is the positive terminal on this battery?
Polarity: positive on the right. To identify it, place the battery in front of you with the terminals facing you and check which side the positive (+, marked with a red ring) is on. Before buying, verify the polarity matches your current battery: switching polarity forces longer cables or system reconfiguration, with short-circuit risk.
What ETN and EAN codes does the Optima YTR-2.7J battery have?
The manufacturer reference (MPN) is YTR-2.7J and its ETN code is 8721760008882 (short form 872 176 000), the European identifier used in spare-part catalogues. The EAN-13 barcode is 4016987113622. It belongs to the OPTIMA YELLOW TOP range. Any of these codes identifies exactly this battery when requesting quotes or comparing prices.
