Frequently asked questions

Is the Tudor TF1421 suitable for a 12V system?

Yes, if they are identical. Two 12V units of 142Ah in series give double the voltage; in parallel they give double the capacity at 12V.

How are the terminals arranged?

This battery has positive on the left-hand side. Compare with your old unit; if they differ, the cables may not reach.

Care tips for lead-acid batteries

During discharge, the plates and acid form lead sulphate and water. Flooded batteries offer strong starting current at a fair price. A fully charged battery resists freezing far better than a flat one.

Fitting and everyday care

Coaches with long stops and the heating on drain their batteries faster than drivers expect. Disconnect the series link before charging the two batteries separately at 12 volts. After several hard winters, most heavy-duty batteries are ready for retirement.
