So far, it works fine. Very quick delivery. Price OK. I was impressed by the phone call which followed up my on-line enquiry. I hope it lasts longer than the similar 501 from another supplier which went down after only 18 months. Would be 5 starts but it arrived full of acid ..... and with 4 bottles of acid which I now have to get rid of.
An excellent "vintage" battery with modern performance and first rate service from Tanya. I have recommended them to the Lancia Motor Club.
