Ok this is going to be long winded but bear with me, the part number is an industry standard part number and can be quoted anywhere, i have also included terminal postions, read as if the battery is at your feet and you are looking down on top of the battery and the terminals are nearest to you.
069= positive terminal left, negative terminal right, 550 cold cranking amps, 65 amp hour, retail £73 trade £60 plus vat.
075= positive terminal right, negative terminal left, 470 cold cranking amps, 54 amp hour, retail £51 trade £42 plus vat.
065= positive terminal right, negative terminal left, 420 cold cranking amps, 50 amp hour, retail £48 trade £40 plus vat.
027= positive terminal right, negative terminal left, 445 cold cranking amps, 55 amp hour, retail £60 trade £49 plus vat.
these batterys are made in the Delphi (lockheed) factory as a cheaper option to their own brand stuff and come with a two year warranty and we dont get many probs with them. there are cheaper batterys again with a lot lower amp ratings which i was going to price up too but didnt get chance, we also offer several grades of trades rates, the one ive quoted is if you walked in off the street and we had sold you a couple of bits before in the past and you asked for trade. the main thing to remember with batterys is your alternator output for recharging and also useage ie is the engine battery also your source for your living electrics in the back.
I'd rather have a bottle in front of me than a frontal labottomy!
