I replaced my 4/4 battery with a Halfords one of same dimensions and output.
Dimensions that would fit the car and not necessitate alterations.
Output to match engine/car requirements re Ah and cranking output.
Ctec also used to keep it in good nick, especially in winter with lower mileage.
The plus8 I now have came with an Odysey battery installed. Impressive battery and Ctec protected. Don't know its age but after 3 years of ownership still going strong.
