Frequently asked questions about the Varta YB9-B
Varta YB9-B or TB9 (FA)?
Compared with the YB9-B, the Varta TB9 (FA) has 15 A more cranking power and AGM technology. If your current battery says 100 A or more, choose the TB9 (FA); if it says 85 A or less, the YB9-B is enough. Both measure 136 × 76 × 139 mm, so they fit the same tray.
What is the difference between the Varta YB9-B and the YB9L-B?
They are the same battery with the terminals swapped: positive terminal on the left on the YB9-B, positive terminal on the right on the YB9L-B. Look at your current battery with the terminals facing you and pick the one that matches. That is why their ETNs only differ in the middle group: 509 014 009 for the YB9-B and 509 015 009 for the YB9L-B.
Is the Varta 509014009 the same battery as the Varta YB9-B?
Yes. 509014009 is the ETN code Varta uses for its YB9-B battery, so you can search for it by either code.
How much does the Varta YB9-B weigh?
The YB9-B weighs 2.98 kg. For reference, the Varta TB9 (FA) (9 Ah) weighs 3.08 kg.
Which battery is equivalent to the Varta YB9-B?
With the same dimensions, polarity and similar capacity you have the Exide 12N9-4B-1, Exide EB9-B and Exide EB7-A. As the YB9-B is a conventional battery, an EFB or AGM of the same size also works.
Which charger does the Varta YB9-B need?
An automatic lead-acid charger with cut-off or maintenance mode, rated at 10 to 20% of its capacity in amps. If it is a vented type, check the electrolyte level and top up only with distilled water.
Inside the YB9-B: lead-acid technology
