Frequently asked questions about the Varta YT4L-BS

YT4L-BS or YTX4L-4 (FA): which one suits me?

Compared with the YT4L-BS, the Varta YTX4L-4 (FA) has 10 A more cranking power. If your current battery says 50 A or more, choose the YTX4L-4 (FA); if it says 40 A or less, the YT4L-BS is enough. Both measure 114 × 71 × 86 mm, so they fit the same tray.

Is the Varta 503014004 the same battery as the Varta YT4L-BS?

Yes. 503014004 is the ETN code Varta uses for its YT4L-BS battery, so you can search for it by either code.

How much does the Varta YT4L-BS weigh?

1.39 kg, with 3 Ah of capacity. For reference, the Varta YTX4L-4 (FA) (3 Ah) weighs 1.4 kg.

Which side is the positive terminal on the Varta YT4L-BS?

On the YT4L-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.

Which charger does the Varta YT4L-BS need?

A charger with an AGM mode that limits voltage to about 14.4-14.7 V. Never an old unregulated charger: overcharging dries out an AGM beyond repair.

What it means that the YT4L-BS is AGM

Inside, the YT4L-BS has glass fibre separators (AGM) that hold the electrolyte. It is fitted in cars with advanced Start-Stop and in deep-cycle equipment.
