Can I install a higher capacity battery in my LTI FX 2.5 D?

Yes, you can install a higher capacity (Ah) battery as long as the physical dimensions fit your LTI FX 2.5 D battery compartment and the positive terminal position matches.

What battery fits the Lti Fx 2.5 D?

The Lti Fx 2.5 D requires a battery with the correct capacity (Ah) and Cold Cranking Amps (CCA) for this engine. Compatible batteries offer 120 Ah, 780 A (CCA), 12 V, case LOT 7, conventional flooded technology. Browse the compatible battery list below.

How many Ah does the Lti Fx 2.5 D battery need?

The exact Ah rating for the Lti Fx 2.5 D depends on the vehicle's original electrical consumers. Compatible batteries offer 120 Ah, 780 A (CCA), 12 V, case LOT 7, conventional flooded technology. Use our finder for a precise recommendation.

How long does a battery last in a Lti Fx 2.5 D?

With normal use, a battery for the Lti Fx 2.5 D lasts 3–5 years. A healthy alternator and avoiding deep discharges significantly extend battery life.

What type of battery does my car need?

You need the make, model and engine. If your car has Start-Stop (the engine switches off at traffic lights), it needs an EFB or an AGM battery, depending on what it came with: if it has an AGM, fit another AGM; if it has an EFB, another EFB or an AGM. On cars with battery management (BMW, Mercedes, VAG group…), moving from EFB to AGM requires coding the new battery. Without Start-Stop, a conventional battery is fine, or an EFB or AGM if you want a longer life.

What is the difference between AGM, EFB and standard batteries?

A conventional (lead-acid) battery is for cars without Start-Stop. An EFB is a reinforced conventional battery for basic Start-Stop. An AGM offers the highest performance and is fitted as standard on cars with advanced Start-Stop, regenerative braking or high electrical demand. Replacement rule: an AGM only with another AGM; an EFB with another EFB or an AGM; a conventional battery with any of the three. Never move down in technology.

Based on the batteries we found for your vehicle, our experts help you pick the right one.

📋 What we found

For your LTI FX 2.5 D we found 4 compatible conventional (non Start-Stop) batteries.

📏 Battery size

The list contains batteries in different sizes or capacities (Ah). In many cases both variants fit, but it's worth checking your compartment dimensions and the Ah of your original battery before buying. Choose the one with the same dimensions as your current battery: a bigger one may not fit the compartment or the hold-down. If several match your size, the higher capacity gives more headroom for cold starts.

⚡ Battery type for your vehicle

✓ Your LTI FX 2.5 D does not need a Start-Stop battery. The conventional ones shown fit your vehicle and are the most affordable option. If you want a higher-quality, longer-lasting battery, you can also fit an EFB or AGM as an upgrade — they are fully compatible and last more years.

Before you buy: check 3 key points

Although the batteries shown are sourced from information provided by manufacturers, we recommend checking on your current battery:

Dimensions (length × width × height, including terminals and protrusions)
The dimensions shown are the maximum of the battery and include the height of the terminals, small ridges at the base and any lateral protrusions. Measure your current battery completely, from edge to edge. The new one must be the same size or slightly smaller — never larger, it would not fit in the housing.
Positive terminal (left or right viewed from the front — check the battery photo carefully)
Stand facing the battery, with the manufacturer's label facing you and the terminals on top. Locate the terminal marked with +: if it is on your right, it is "positive right"; if it is on your left, it is "positive left". Do not rely on how the battery is mounted in the car — the position is always measured looking only at the battery itself.
Technology (AGM, EFB or conventional — the same as your current battery or higher)
Depending on the manufacturer, the same technology may be labelled differently: AGM may also appear as VRLA, AGM Start-Stop or AGM Deep Cycle. EFB may appear as EF, EFB+ or Enhanced Flooded Battery. Conventional may appear as SLI, Lead-Acid, Wet or Standard. If your vehicle has Start-Stop, the battery must be AGM or EFB — never conventional.

If you have any questions, just ask us and we'll be glad to advise you with no obligation.
