Bosch battery guarantee?
Harry Bloomfield
months and a receipt to prove when it was bought. I read that someone
had been told they could take the dud to any Bosch dealer for
replacement, is that true?
I tried Halfords and they said I HAD to take it back to where
purchased.

I have not been able to get a definitive answer. Apparently the seller can
choose their guarantee period and conditions. Costco will only deal with
Bosch batteries they have sold from any of their own stores, their guarantee
used to be 5 years and has now been dropped to 4. He suggested that you
might want to contact Bosch directly and ask them about it.
Sorry it is not better news.

Well thanks for your efforts.
I managed to get through to Bosch themselves this morning and they said
it had to go back to where purchased. Unfortunately a single outlet
place, but luckily not too far away - could have been very awkward if
it had been bought 300 miles away.
Took it back to the original supplier and they managed to get it to
charge up and it seems to be holding it so far. The car only usually
gets to be used at the weekends, but it only does good long runs and is
often kept on a battery maintainer. Last weekend it wasn't on a
maintainer and was completely flat, having done a couple of hundred
miles the weekend before. I put enough charge in it to start it, did
100 miles and it was left until yesterday and found to be completely
dead again.
I have a couple of chargers which will not charge a dead battery and
another three which will, but none of them could manage to bring the
battery back to life yesterday. Even a spare good battery in parallel
via jumpers could not start the car, yet it started first touch with
the spare battery just lashed up in place of the Bosch.
I checked the discharge with key off and temporary battery fitted -
that was 500mA initially, then fell to 200mA, then fell again to 100mA
and I suspect fell even more some time later. Engine running it was
14.2v with the Bosch refitted.
So I am now quite puzzled as to why the battery was flat in the first
place and why I could not get a charge into it yesterday.
Mrcheerful
That sort of concurs with what my bloke said:ask the actual supplier.
max discharge should be 30ma or less. 14.2 is not particularly high. my
first thought is that there is an internal break in the battery. you need
to leave jumper leads connected for a good few minutes if a battery is
really flat before trying to start it, unless you have a monster battery and
very heavy duty leads.

It was left connected for several hours and made no difference, yet the
same spare battery started it instantly once I had botched it to the
connections - posts on the car, flat terminals on the battery.
Voltage across the Bosch when I took it in was 9.79 yet their test
instrument(?) suggested the battery was good, just flat.
Mrcheerful
10 volts says to me that one cell is absolutely duff, probably the junk that
falls off the plates has bridged the plates, thereby sort of avoiding that
cell altogether.

Modern electronic testers can give the condition of the battery even when
not fully charged. Although mine won't work on a battery reading 9.79
volts open circuit. That is totally discharged in practice.

Sorry, that was the OBD's reading which I meant to translate to a
correct value. My Fluke suggests 14.5 to 14.6 at a tick-over, adding
headlights on makes no difference to the reading.
