The Tudor TB621 in practice
When not to choose it
Not for Start-Stop or regenerative braking; those need EFB or AGM. Nor if the original had more capacity or cranking: never downwards.
Car battery Tudor TB621 Technica 62Ah 540A 12V
The Tudor TB621 from the Technica range delivers 62 Ah and 540 A of cold cranking current (EN) at 12 V: the usual specification for passenger cars with conventional starting, without a Start-Stop system. It measures 242 × 175 × 190 mm and the positive terminal on the left, the format sought by anyone replacing a 62 Ah battery in cars.
In short: the Tudor TB621 (62 Ah, 540 A, 242 × 175 × 190 mm, positive terminal on the left). It is a conventional battery for cars without Start-Stop: if yours has Start-Stop, it needs an EFB or AGM battery of the same size. Verified equivalent alternatives: Varta D43 and Exide EB621.
- Reliable cold starts, even after weeks without driving.
- Conventional lead-acid: the most proven and economical technology.
- Original-equipment build quality without the dealership price.
- Direct replacement for the original battery in size and terminals.
Size, terminals and hold-down of the Tudor TB621
It has external dimensions of 242 × 175 × 190 mm and weighs 14.40 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. 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 Tudor TB621 is for
With 62 Ah, the Tudor TB621 is sized for passenger cars with conventional starting, without a Start-Stop system. It is a direct replacement for the original battery as long as dimensions and terminals match. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 14.40 kg.
The Tudor TB621: Technica range and conventional lead-acid technology
The TB621 is part of the Tudor Technica range. Choosing the right reference within the series comes down to capacity, dimensions and terminals: technology and quality are common to the whole family.
Conventional lead-acid is the benchmark against which other technologies are compared: good cranking current, great tolerance to alternator charging and the best price per amp-hour.
Tudor: the maker behind the TB621
Tudor has made batteries in Spain for more than a century and remains one of the brands most trusted by Spanish workshops for reliability and value. At baterias.com we work directly with the manufacturer or its official distributor: real stock, brand-new product and official warranty.
Official warranty
The Tudor TB621 comes with the manufacturer's official warranty against manufacturing defects; the exact period is stated in the brand's conditions. If it fails through a defect within the period, we replace it free of charge.
Usage and maintenance tips
In normal daily use the alternator keeps the battery charged; if the car stands for weeks, a maintenance charge once a month prevents deep discharge. Avoid leaving lights or accessories on with the engine off: most batteries fail not through defects but through repeated deep discharges.
Shipping, delivery 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
How is the Tudor TB621 battery installed in the vehicle?
Our blog guide covers it in detail; if the owner's handbook describes a different procedure, follow the manufacturer. With a 10 mm spanner, swapping in the Tudor TB621 takes 15 to 30 minutes on most cars; if the battery sits in the boot or under a seat, allow up to twice as long. What matters most is the terminal order: removing, negative (−) before positive (+); refitting, positive (+) before negative (−). In between, with the engine off and the key out, release the clamp and fit the new battery the same way round as the original, positive on the left (polarity).
How long does the Tudor TB621 battery last?
Estimated lifespan of the Tudor TB621: 4 to 6 years in regular car use without Start-Stop. Treat it as an approximate guide, as every case is different. Many factors play a part: how it is used (lots of short trips, for example), temperature (cold makes every start harder and intense heat evaporates the electrolyte), the condition of the alternator and charging system, power drawn with the engine off and maintenance, as well as the type of car and whether it has Start-Stop.
What size is this battery?
The Tudor TB621 takes up 242×175×190 mm (length, width and height, terminals included), the European L2 case size. Before buying, measure the space in your car: one extra millimetre can stop the hold-down clamp from closing.
Which side is the positive terminal on this battery?
The TB621 has the positive on the left in a L2 case: that is its polarity. It must match your current battery: reversed polarity means lengthening cables or reconfiguring the system, with a risk of short circuit. Face the battery with its terminals nearest you and see which side the positive post (+, red ring) is on.
Is the TB621 valid for my vehicle?
For your own vehicle: type your number plate into the finder (DGT/DVLA/KBA identify model and engine), check the "Compatible vehicles" tab below, listing vehicles verified by our technical team, or message us on WhatsApp with make, model, engine and year; we reply during business hours (Mon–Fri 10:00–13:30 and 16:30–18:00 (Spanish time, CET)). Our database holds 260 verified vehicle versions for the Tudor TB621. The car manufacturer's specifications always take priority over our tables.
Which batteries are equivalent to the Tudor TB621?
Interchangeable means the same dimensions, same polarity, same Ah and same CCA; for the TB621, 62 Ah (540 A cranking). The "Equivalents" section of this page gathers the recommended options with equivalent performance; remember that in Start-Stop cars an EFB should not be replaced with a conventional battery.
