Before ordering the TZ850, check this
- Length, width and height of the TZ850: 353 × 175 × 190 mm (European case size L5).
- The TZ850 has the positive terminal on the right: compare it with your current battery.
- Capacity of the TZ850: 100 Ah; the same as your current battery or slightly more is fine.
- Check the EN amps on your battery: if it says 900 A or less, the TZ850 covers your engine.
