About the technology: lead-acid

During discharge, the plates and acid form lead sulphate and water. Flooded deep-cycle batteries suit solar and golf buggies. A fully charged battery resists freezing far better than a flat one.

Five checks for a perfect fit

• ✓ Terminal layout: positive on the left-hand side. If your original is the mirror image, choose another reference rather than stretching the leads.
• ✓ The capacity rating, 50Ah, should suit the consumers you run. Lots of electrical equipment calls for the higher end.
• ✓ Starting power: 360A to the EN standard. Match or beat the figure on your current label.
