2002 LS430.
In May 2020 I bought a 5 year Yusua battery at Halfords.
All OK for two years (I trickle charge it occasionally to preserve it), then it started to fail. Halfords tested it and said it needed replacing, which they did with the same battery.
18 months on another failure. Car stood for 2 weeks over Christmas after having done a 100 mile round trip. This time it was so flat the ignition would not work, central looking not working, and I could not get into the boot. My trickle battery charger said it was faulty and would not accept any charge at all.
Off to Halfords and it was so bad it did not ever register anything on their battery testing machine. This time they replaced it with a slightly smaller Halfords 4 year battery they had in stock (it was manufactured in July 2023), so I charged it up. Fitted it and all is well.
Is this just bad luck, or me, or the car?
Have to say Halfords were first class in replacing it twice. Are Halfords batteries any good. Who makes them?
