Five checks for a perfect fit

• ✓ Check that the alternator or controller suits lead-carbon.
• ✓ Tape measure time: 260 × 168 × 233 mm is the footprint and height of this case. Leave a little clearance for the clamp and the cable lugs.
• ✓ Plus pole position: positive on the left-hand side. Mixing up orientation is the most common reason a battery of the right size will not connect.
