What it means that the K4 is lead-acid
Inside, the K4 is classic lead-acid: liquid electrolyte and lead plates. It is a robust, well-known technology with a good capacity-to-price ratio, and still the basis of most cars, trucks and traction equipment.
Check this before ordering the Varta K4
- The K4 needs 514 × 218 × 210 mm of space: measure it with the hold-down clamp in place.
- Your current battery should say about 143 Ah; a little more is also fine.
- Cold cranking: 950 A (EN), equal to or higher than the original.

Frequently asked questions about the Varta K4
Varta K4 or J5?
Compared with the K4, the Varta J5 has 13 Ah less and 270 A less cranking power. The K4 cranks harder; the J5 is only a good option if your original battery says 680 A or less. Both measure 514 × 218 × 210 mm, so they fit the same tray.
What does the code 643 033 095 on the Varta K4 mean?
It is its ETN (European Type Number), also written 643033095. The first three digits (643) encode voltage and capacity: 12 V and 143 Ah (5xx = under 100 Ah, 6xx = 100 to 199 Ah, 7xx = 200 Ah or more). The middle group (033) identifies the specific model within that capacity, and the last three digits (095) multiplied by 10 give the cold cranking current: 950 A.
How much does the Varta K4 weigh?
The K4 weighs 39.85 kg. For reference, the Varta J5 (130 Ah) weighs 37.83 kg.
Which battery is equivalent to the Varta K4?
With the same dimensions, polarity and similar capacity you have the Exide EG1353, Tudor TG1353 and Fulmen FG1353. As the K4 is a conventional battery, an EFB or AGM of the same size also works.
Which charger does the Varta K4 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.
