Battery failing issues

Postby Brian-reynolds » Sat Apr 20, 2019 8:58 pm

A few weeks back, whilst checking my two truck starter batteries, I found a white stringy thing floating in one of the cells which I did not know what it was for.....

I now know......

I went to start the truck one morning last week North of Goole, and found the batteries dead.... not just normal dead, but extremely dead! Both of them! 6 volts total instead of about 27 volts!

Turned out the stringy thing was part of the battery construction which kept the plates apart, or not as the case may be..... so when that detached and the plates touched, it was curtains for that battery, and as it was connected to the second battery, that was also killed!
£200 down the Swanee and a further £260 for two new batteries!!!!

Not happy! But what if that had happened when I was up in the Scottish mountains, miles from anywhere....

On a good note, my solar panels charge the house batteries so I still had power for making a cuppa, but if I had the solar attached to the truck batteries, then used my B2B charger to charge the house batteries, I would have been in a very bad situation as nothing would have been charged......

You can't cater for everything in these builds..... Luckily I was outside my sisters house, so she could take me into Goole for some new batteries.....

So if anyone else see's something floating in their batteries, remove them straight away!

Now to go find the original receipt as I think they are still under warranty......

yes, when you have a mechanical failure of the batteries internal structure there's not a lot you can do, they just need replacing.
Batteries with a cylindrical cell structure don't suffer from this problem the Optima Odyssey batteries are a good example. They tend to be more robust.

regarding your electrical setup brian, if you had a Victron Cyrix device between your house and truck batteries, the solar would keep the truck topped up as well, and if you use thick enough cables you have built in emergency jumpstart as well, (Happy to send you a drawing), it's simple to fit, works well, has no downsides and gives you great backup.

Interesting, thanks Chris.

I currently have a Sterling B2B fitted which did once fail and killed the original truck batteries....

Sterling replaced the complete unit FOC after trying to fix the original fault, but now I am nervous as to when it will fail again....

I will NOT be using Sterling kit again due to "his" attitude to his customers, so another system will be needed at some point....

If it is not too much trouble for you, I would be interested in your system.... I know how much you are into all these things, I have see your workshop!!!!!

I have now seen floating, what looks to me to be adhesive, in 3 cells on one battery and in one cell of the second battery.

The company I bought them from refuse to refund the costs as I have had them for about 2 1/2 years, which is fair enough, but I have now been in contact with Excide themselves for them to investigate the faults, and have attached images of the 4 faulty cells.

I will wait to see how things pan out.... hopefully good, as Excide is a decent company as far as I know.....

Time will tell....

Exide do enjoy a reputation for good quality control and were one of only a few brands that didn't try to hoodwink consumers in the 'rebadged starter battery' scam that came to light about a decade ago. In this scam manufacturers would simply badge batteries designed for engine starting as 'deep cycle' or 'leisure' batteries etc and fob them off on unsuspecting customers at grossly inflated prices.

In the book there's some advice that a vehicle’s starter battery should be utilised for its intended purpose only.

Starter batteries are designed to provide huge cranking power over a very short period and then to be quickly and completely fully recharged. If habitually used outside of this regime they will be killed off pretty quickly.

Battery university quote some useful research claiming that factory defects are rare and amount to less than 7 percent of premature failure.

Charge / discharge regimes dictated by patterns of consumer use are usually the reason battery life is foreshortened.

Exide may have supplied a duff batch but have been shown to be one of the more reliable and honest manufacturers. I'd personally trust their lead-acid stuff; along with Yuasa, Banner and Varta.
