What it means that the N50 is EFB
Inside, the N50 uses EFB technology, a reinforced version of the flooded battery. It is the choice for cars with basic Start-Stop.
Check this before ordering the Varta N50
- The N50 is an EFB: it suits cars that had an EFB or a conventional battery. If yours had an AGM, fit another AGM.
- Check the EN amps on your battery: if it says 550 A or less, the N50 covers your engine.
- Your current battery should say about 50 Ah; a little more is also fine.
- Polarity of the N50: positive terminal on the right (if yours has it on the other side, the cables will not reach).
- Measure the space: the N50 takes up 207 × 175 × 190 mm (European case size L1).
Frequently asked questions about the Varta N50
N50 or A9: which one suits me?
Compared with the N50, the Varta A9 has 10 A less cranking power and AGM technology. The N50 cranks harder; the A9 is only a good option if your original battery says 540 A or less. Both measure 207 × 175 × 190 mm, so they fit the same tray.
What does the code 550 500 055 on the Varta N50 mean?
It is its ETN (European Type Number), also written 550500055. The first three digits (550) encode voltage and capacity: 12 V and 50 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (500) identifies the specific model within that capacity, and the last three digits (055) multiplied by 10 give the cold cranking current: 550 A.
Can the Varta N50 be used in a car with Start-Stop?
Yes, the N50 is an EFB: it suits Start-Stop without brake energy recovery, or cars that already had an EFB. If your car left the factory with an AGM, fit another AGM.
How much does the Varta N50 weigh?
14.18 kg, with 50 Ah of capacity. For reference, the Varta A9 (50 Ah) weighs 14.72 kg.
Which battery is equivalent to the Varta N50?
In EFB or AGM, with its dimensions and polarity: Varta A9. A conventional battery does not replace the N50.
What case size is the Varta N50?
Case size L1: 207 × 175 × 190 mm (Varta lists it as H4/L1). The N50 fits any standard L1 battery tray such as the Varta A9.
Which side is the positive terminal on the Varta N50?
On the N50, the positive terminal is on the right with the terminals facing you: compare it with your current battery, because with reversed polarity the cables will not reach.
