I bought a Battery previously from TANYA batteries after 8 months I noticed that on the odd occasion it just wouldn't start even after a charge it still sometimes failed, anyway after getting back to TANYA and explaining my occasional fail they pointed out that the one they sold me ( EUROLINE 48 ) was only 40Ah and 345A en. The one fitted was 45Ah 420en,anyway I must say they were really helpful and exchanged it fur a more powerful battery  BANNER 55Ah 460en and gave me a full refund. since the exchange (fingers crossed ) no problems.... at all.

after having the same problem myself i have found out that the CCA of the Battery should be at least CCA420. this is the engine crank amp rating, anyway I've just ordered a higher rated CCA 450 and i'll let you know later how this works.
