• Vehicles are sometimes made in different factories in different countries, and these can be sometimes fitted with batteries of different types and sizes.
  
  
• Vehicles can be 'grey imports' into the UK, generally from Japan, and these often do not have the same batteries as those on similar vehicles that are normally imported into the UK.
  
  
• Vehicle manufacturers sometimes change the type of battery during a production-run, perhaps as the result of a supply problem with the specified battery, or perhaps on the occasion of a face-lift.

For this reason, we always recommend that the customer should place the old and new batteries side by side to compare dimensions, polarities, hold-downs and performance levels.
