## Frequently asked questions about the Varta YTX30L-BS

Compared with the YTX30L-BS, the Varta TX30L (FA) has 65 A less cranking power. The YTX30L-BS cranks harder; the TX30L (FA) is only a good option if your original battery says 385 A or less. Both measure 166 × 127 × 175 mm, so they fit the same tray.

### Is the Varta 530905045 the same battery as the Varta YTX30L-BS?

Yes. 530905045 is the ETN code Varta uses for its YTX30L-BS battery, so you can search for it by either code.

### Which battery is equivalent to the Varta YTX30L-BS?

Only other AGM batteries with its dimensions and polarity: Exide AGM12-31. Neither an EFB nor a conventional battery replaces the YTX30L-BS.

### Which side is the positive terminal on the Varta YTX30L-BS?

On the YTX30L-BS, 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.
