How do I find the right battery for my vehicle?

Use the search tool by selecting your vehicle's make and model. Our system automatically filters compatible part numbers verified by our technicians. If you have any questions, contact us via WhatsApp.

What warranty do the batteries have?

As they are consumable items, car batteries have a 2-year warranty, truck batteries a 1-year warranty, and all others (motorcycle batteries, cyclic batteries, etc.) a 6-month warranty. If a battery has a manufacturing defect, it will be replaced at no cost to the user.

How long does it take for the battery to arrive?

Under normal circumstances, batteries usually arrive within 1 to 2 days of ordering. However, there are some cases where delivery may take a little longer: peak seasons (Black Friday, Christmas, etc.), palletized shipments, occasional stock shortages, etc.

How long does delivery take?

In mainland Spain and Portugal delivery takes 24 working hours if you order before 17:00 and the battery is in stock; for the Balearic Islands, the Canary Islands and other EU destinations allow 2 to 5 days. Batteries are shipped fully charged and ready to install.

Does your Mercedes-Benz O 405 O 405 G,O 405 Gn,O 405 Gtd,O 405 Gntd,O 405 Gnde, Bus, 6X2 (2009) have a Start-Stop system? It shuts the engine off at short stops (traffic lights, jams) and restarts it automatically when you release the brake/clutch. If your dashboard has an "A-OFF" button or an engine icon with a circular arrow, it has it.

⚠ Then you need a battery designed for Start-Stop (EFB or AGM). We have hidden the conventional batteries from the list: fitting them in your car would ruin the battery within months and could damage the alternator. The batteries below are built for the frequent charge/discharge cycles of Start-Stop. 💡 Great. You can buy either a conventional or a Start-Stop (EFB or AGM) battery: a Start-Stop battery is perfectly valid in a non-Start-Stop car and is actually more robust (longer life, better cold-start performance). It is just a bit pricier. On vehicles older than year 2000, an EFB is preferable to an AGM: legacy alternators charge at a fixed voltage without temperature compensation, and an AGM needs a more precise charging profile to avoid losing life quickly — an EFB tolerates the classic alternator profile better. 💡 If in doubt, play it safe: buy a Start-Stop battery (EFB or AGM). It works in Start-Stop cars and non-Start-Stop cars alike, lasts longer and avoids any risk. You only pay a few euros more than a conventional one.

📋 What we found

For your Mercedes-Benz O 405 O 405 G,O 405 Gn,O 405 Gtd,O 405 Gntd,O 405 Gnde, Bus, 6X2 (2009) we found 3 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. If in doubt, choose the one with higher capacity: provided the size fits, it gives more headroom for cold starts and accessories.

⚡ Battery type for your vehicle

✓ Your Mercedes-Benz O 405 O 405 G,O 405 Gn,O 405 Gtd,O 405 Gntd,O 405 Gnde, Bus, 6X2 (2009) 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.

📊 View AGM vs EFB vs Conventional — full comparison

Here are the key differences between the three starter battery technologies. AGM is the most advanced technology (and the priciest); EFB is the middle ground for basic Start-Stop; conventional (also called flooded lead-acid) is the classic choice for non-Start-Stop cars.

	AGM	EFB	Conventional
Charge cycles	Up to 3× more Start-Stop cycles than a conventional (cycle endurance certified to VDA standard)	~2× more Start-Stop cycles than a conventional (cycle endurance certified to VDA standard)	Designed for start + alternator, not for repeated cycles
Expected life	5-7 years under average use	4-5 years under average use	3-4 years under average use
Start-Stop compatible	✓ Yes, even advanced systems (regenerative braking)	✓ Yes, basic and mid-range Start-Stop	✗ No — degrades within months
Cold start	Excellent (higher CCA)	Very good	Adequate
Relative price	€€€ (highest)	€€ (mid)	€ (lowest)
Recommended for	Premium cars with advanced Start-Stop, many electrical accessories, heavy urban use	Mid-range Start-Stop cars, mixed city/motorway use	Non-Start-Stop cars, standard use, tight budget
Replacement rule	Replaces AGM and EFB; NEVER use EFB where AGM was original	Replaces EFB and conventional; does NOT replace AGM	Only conventional; not suitable for Start-Stop

For your Mercedes-Benz O 405 O 405 G,O 405 Gn,O 405 Gtd,O 405 Gntd,O 405 Gnde, Bus, 6X2 (2009) we recommend the VARTA N9 (PLOMO/ACIDO, 225 Ah). It also offers the highest capacity (Ah) and the highest cranking power (CCA) on the list — more headroom in cold starts and with many consumers. Varta is the world's leading manufacturer of starter batteries and supplies first-equipment (OEM) batteries to the major European car makers.

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 — Start-Stop requires AGM or EFB)
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.

Start Stop Battery
