Does charging your car battery on fast charge damage it?

[Speedy Builder5Participant @speedybuilder5]

Over the past few months, the Stop `Start function of my Renault Clio 4 had stopped working with a fault message displayed on the console.

The car went in for its service and I happened to mention this "fault". The garage rang me to say the battery was on its way out and the car's logic had disabled Stop Start – did I want a new battery ? They quoted a price which I accepted. The battery was an original and just under 8 years old, so its been a good battery in its lifetime.

I have just paid the bill – no great surprise however attached to the bill was the battery test printout:-

48% Health of battery

47% Charge of battery

12.26 volts at state of rest

Perhaps I should have waited to replace the battery and used up a bit more of its life, but as batteries can fail when old, and living in the countryside, thought it wise to replace it. I doubt I will buy another one for this car.

MANY years ago, ran a very secondhand Ford 100E (Had a vacuum tank which would support a wiper motor powering two arms The vans had only one at first )

The Shrewsbury works tmotor club had a deal set up with a company in London, and since the staring method was already me and staring handle, when visiting parents in north London, drive to east London for the new battery.

Stopped on the front, and went in "Bring it in" , but battery was SO dead that would not start off the handle. The third cell failure was too much!

In contrast, our late 2005 Toyota Yaris battery was still functioning well after 12 years, despite being smaller capacity and having a far greater electrical load than the 100E! The march of progress in materials and control systems

Our company operated a private micro link between Longbridge, Cowley, Swindon and London, we covered the maintenance of the Cowley and London equipment and the relay at Christmas Common to get over the Chilterns, the route to Swindon was also via Christmas Common. When I joined the department that covered the maintenance of this equipment I didn’t realise that an excellent pub was next to the Christmas Common equipment so I manned the Cowley end while the other two lads went to top up the batteries and then we would check the circuits to Cowley. It was about a 25minute drive from Cowley so after a very long wait at the Cowley radio room they finally called me, apart from the maintenance checks it also turned out the Brakespears ales at the Fox also needed to be checked out.
