Tudor TB858: dimensions and ratings
Installation and maintenance tips
Classic cars stored in a garage all winter are famous for flat batteries in spring. Lift the battery straight up, never by the terminals. A rotten-egg smell near the battery points to overcharging.
Care tips for lead-acid batteries
Wet lead batteries started engines long before the first motorway was built. Fleet vehicles often use flooded batteries for value. Keep a flooded battery charged in cold weather.
Will the Tudor TB858 fit?
- ✓ Rated 85Ah: check that the charger or alternator in your system can refill a battery of that capacity in reasonable time.
- ✓ Starting current 800A: look for the EN value on your old label and choose this reference only if it is equal or higher.
- ✓ Set your charger to lead-acid before the first charge.
