My original Toyota battery lasted 7 years, 69,000 miles, and it looks like the Halfords battery HCB012 which I replaced with a similar battery last year, lasted 12 years, unless I fitted two previous batteries not one, in which case the Halfords batteries lasted about 6 years. I've mislaid my service manual, so I cannot confirm that, my photo copies of it only go up to 2011. The car is 20 this year. The prescribed battery by Halfords did not fit the carrier, so I had to buy a smaller battery, but it has always started the car first time. However, I always plaster the terminals with loads of Vaseline.
