Updated: · Technical data from the manufacturers' datasheets (how we write our datasheets)
This page brings together all our guides to help you choose the right car battery first time. Each guide compares real data from the manufacturers' datasheets and links straight to the batteries in our range that match it.
If you already know your battery's reference, start with the equivalents table; if not, measure your current battery and check the size guide, or browse all car batteries.
Varta battery comparisons
- Varta E11 vs E44: the differences and which to choose: capacity, cold cranking, weight and ETN of the two best-selling Varta L3 batteries, and when each one makes sense.
- Varta A7 (formerly E39): what changed and equivalents: the successor to the E39 with unchanged performance; what an AGM battery is, how it differs from the N70 EFB and which AGM equivalents are available.
- Varta A7 vs A6: the differences and which to choose: Varta's AGM batteries in L3 and L4 format, heirs to the E39 and F21, and why you should never step down to an EFB.
- Varta N60 vs N70: how the two EFB batteries differ: two Start-Stop EFB batteries of different lengths, with their AGM and Exide alternatives.
- Varta E11 vs E12: the same battery with reversed polarity: identical apart from the side of the positive post; we show you how to check before ordering.
Exide battery comparisons
- Exide EL600 vs EL700: how the two EFB batteries differ: what each letter in the code means, how the two differ and which Varta corresponds to each.
Equivalents and sizes
- Varta, Bosch, Exide and Tudor car battery equivalents table: matching batteries from Exide, Tudor, Fulmen and Deta for 17 Varta references, along with the Bosch sharing the ETN code as a pointer.
- Car battery sizes: L1-L6, LB1-LB5, B and D (Asian) cases: length, width and height of every European and Asian case size, the hold-down code and the Varta batteries in each format.

How we handle the data
Every guide follows the same rule as our product pages: we only publish data shown on the manufacturer's datasheet or in our catalogue. We explain it in how we write our battery datasheets.

Frequently asked questions
How do I know which battery my car needs?
Check the label on your current battery: the reference (for example E11) or the 9-digit ETN code is enough to find the same battery or an equivalent in the equivalents table. If it is illegible, take the battery's length, width and height and note which side the positive post is on.
Do the guides cover Start-Stop batteries?
Yes. The Varta A7 guide explains the difference between AGM and EFB, and the equivalents table respects the technology: for an AGM battery we only suggest AGM equivalents.
