Being in possesion of several battery banks at home and looking after 5 at work I just thought I'd pass this on to anyone thinking of buying batteries from 'William Wilson' of Glasgow.


This is the third set of emergency batteries we've fitted in 4 years, the sewage plant and the main engine banks have all had similar failiures. They're topped up weekly and the SG checked and recorded. None are discharged deeply and they're maintained at float on good chargers. I just think they're poor batteries. I'm not complaining because we change the whole banks when just a few cells have failed and I can use the good cells at home but I'd never but one for my own battery bank.

Cheers, Paul

Paul n everyone,we run several vans at work,and various tractors at home,and it seems a bit of a lottery when you buy a new battery,(was that from a gilbert and sullivan opera Huh)all are properly maintained,but some last for years,others struggle on the first frosty morning of the following year;when I look around for another supplier,they all seem to sell the same brand (starting bull or something,probably made by ethnic americans) when you take one back under warranty,some spotty boy starts a long piece on''well its probably your alternator,better change it'' etc;eventually replacing the battery but charging a percentage of the cost for the months of service you had from it;like many industies,the motor trade now seems to be all about immense profits on the back of cr+p product and poor warranty

With the old D.C. generators and very crude electro mechanical voltage regulation they should have failed much quicker but they still seemed to last much longer. They could be made to last nowadays, there was a brand called Samson which had a guarantee for as long as you owned the vehicle. Donít know what happened to them, maybe gone out of business because they lasted to long.

Not related to green issue's or battery back up but i have personally killed 3 batteries in cars in the last 20 wears since the newer light weight non solid electrodes have come in.

My own fault I tried to start the car in gear without putting the clutch in by mistake not intentially, the battery goes open circuit as if they have an internal fuse.

This makes a mockery of the method to get you off a train crossing if you break down on one.
