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.
