## What it means that the TG1803 is lead-acid

## What to look at before buying the TG1803

- Measure the space: the TG1803 takes up 513 × 223 × 223 mm.
- With 180 Ah, the TG1803 replaces an original battery of that capacity or slightly less.
- The TG1803 delivers 1,000 A cold cranking (EN standard); do not go below what your original battery states.

## Frequently asked questions about the Tudor TG1803

### Tudor TG1803 or TJ1723?

Compared with the TG1803, the Tudor TJ1723 has 8 Ah less and 390 A more cranking power. If your current battery says 1,390 A or more, choose the TJ1723; if it says 1,000 A or less, the TG1803 is enough. Both measure 513 × 223 × 223 mm, so they fit the same tray.

### How much does the Tudor TG1803 weigh?

The TG1803 weighs 42.8 kg. For reference, the Tudor TJ1723 (172 Ah) weighs 48.8 kg.

### Which battery is equivalent to the Tudor TG1803?

With the same dimensions, polarity and similar capacity you have the Exide EG1803, Varta M18 and Kronobat SHD-180.3. As the TG1803 is a conventional battery, an EFB or AGM of the same size also works.

### Are truck batteries fitted in pairs?

Almost always, in series for 24 V. Replace them in matched pairs: mixing a new one with an old one unbalances charging and shortens the new one's life.
