Inside the J8: lead-acid technology
The J8 is a conventional lead-acid battery, with plates immersed in liquid electrolyte. In cars without energy management, the J8 needs no special registration: just connect it.
Check this before ordering the Varta J8
- The J8 needs 360 × 253 × 240 mm of space: measure it with the hold-down clamp in place.
- Your current battery should say about 135 Ah; a little more is also fine.
- Check the EN amps on your battery: if it says 680 A or less, the J8 covers your engine.
