Recovery AA and RAC make commission on every battery they sell a customer so just be sure you actually need one
I‘m sure that you are right Azzy, but to be fair to the AA chap that came to me he said that if it were his car he wouldn’t change it now as it didn’t fail the charge retention test, it scored 50% (the battery is five and a half years old but the cars only done 22,000 miles from new). He also said that I might be able to get one cheaper elsewhere if and when we need one.
