Hi, I have a car that is not used much. I bought a new battery last easter and moved the car when I took the battery home. About a month later I went to move the car again and the battery was dead, no ignition light. I cant remember how I charged it. The two subsequent times I have tried to move it the battery has had to be charged and I have used a fancy charger borrowed from a friend because my bog standard charger cant put charge into it at all.
Is the battery likely to be knackered? Is it my fault for leaving it for a month to loose the charge?

Modern car batts don't respond well if deep discharged - so there is a
fair chance it well on the way to knackered.

Car batts ever have responded well to being discharged. The op may well
find that something like an alarm or immobiliser is slowly discharging
the battery. If you are leaving it unused for some time best disconnect
one lead.

yep, all manner of stuff is quietly running when the car is "off".
Mine apparently is aware of this problem and if the battery voltage
gets too low (FSVO "too low") it goes into a really deep sleep and
has to be opened manually, via the one door that actually has a
(hidden) key hole.

Or do as I did when I left my car unused for the last month. A small
solar panel(*) on top of the dash board facing SE, connected to the
battery. Car opened and started without a hint of a flat battery. Not
conclusive, one would need to leave it for a month without the solar
panel and see if it went into deep sleep, that's not going to happen.

Well to be fair SOME onboard computers may lose SOME of their

Examples a car radio anti-theft kicking in and needing the code to be
re-entered.

*some* immobilisers kicking in, and the car won't start

*some* other systems losing their marbles. ISTR that sometimes window
warning lights come on until various resets establish where 'window

OBC usually refers to a user 'computer' on the car that does things like
MPG and journey times, etc. The ones which control the engine etc more
commonly called an ECU. (electronic control unit)

It's quite possible a flat battery can cause some things to be lost. Maybe
the radio station memory. But a very poor design if it is anything
important.

Many ECUs do 'learn' how the car is driven to some extent. But should
default back to the factory settings if the battery is disconnected for
some time. And quickly learn again. The ECU controlling an auto gearbox
being the obvious one. But in any case updates quickly if you alter your
driving style.

Not heard of any car that becomes brain dead or confused if it any of
its computers loses power. The ECU may well forget the engine
settings but it will then load a basic "these will work" set and
relearn the engine over the next hundred miles or so.

Note "computers", a modern car has loads of the things. Very few if
any sub-systems don't have a processor of some sort
controling/watching over/reporting that sub-system. "Sub-system" can
mean a single door...

Yes even when the car is just sitting there some do use quite a bit out of
the battery as people soon find out to their cost. The old dodge of
disconnecting it is no good as somemany bits of the car seem to lose their
memories when you do that, according to a breakdown guy over the road who
seems to be one of those loud voiced blokes who lets his wisdom flow
loudly. Lets just say its yet anothreason why I'm not bothered by not being
able to drive....

Alas probably yes.

If you're using the car that infrequently it may be time to think about
alternatives. Hiring a car once a month would be a lot cheaper that
keeping/taxing/insuring/replacing the battery on a car used that
infrequently.

The other solution, unless it is parked on the road, is to keep it wired
up to a small trickle charger. A motorbike one would be enough.

I have a small van which is sometimes left for a month or so, and it has
a small battery which is readily flattened if the lights are left on
(e.g. in a shopping centre car park: being a very basic van it does not
have a "bleeper"). My "fix" for that is to keep something similar to
this in it. (Also comes in handy as a phone charger). These hold their
charge for ~ 6 months.

Worked for me. At least the car was quite happy when I came to unlock
and start it up after being left for a month. I don't intend to
perform the opposite test leave it a month without the solar panel. I
might see if I can measure how much draw there is once it's been
"off" overnight as cars tend to have several sleep states.

But even if the solar panel is only providing half of what is taken
that doubles the lenght of time it takes for the car to go into a
coma.

Fit a battery isolating switch. Battery should stay up for about 3
months minimum.Would then need recharging. Alternatively fit a plug in
trickle charger. I have to do this on one of our cars.

Most modern cars still draw current even when switched off.

Dunno what you mean by modern. Some car radios needed a standby battery
feed 40 years ago. And obviously anything with an alarm.

Hi, I have a car that is not used much. I bought a new battery last
easter and moved the car when I took the battery home. About a month
later I went to move the car again and the battery was dead, no
ignition
light. I cant remember how I charged it. The two subsequent times I
have
tried to move it the battery has had to be charged and I have used a
fancy charger borrowed from a friend because my bog standard charger
cant put charge into it at all. Is the battery likely to be knackered?
Is it my fault for leaving it for a month to loose the charge?

You'd need to contact the maker and see how long they reckon it can be
left without use. Remember reading of one where the makers said it
couldn't be left for three weeks while going on holiday...


Chrysler Voyager.

Sell it.




For yours to have gone fully flat something is discharging it .... put
an ammeter on the lead to check for current draw .. if none you may have
a faulty cell dragging the battery down.

If it is not sealed check each cell with hydrometer - or get it fully
charged and do a drop test on it.

Buy a multi-stage charger and leave it connected to the battery.
I have a winch in my boat shed top winch in boat and trailer ..... I
leave battery permanently hooked up to a CTEK MKS 5 smartcharger

When you first hook it up it does a full recondition charge.

Got mine for a good price on eBay


I also have batteries on boat which are intermittent use so have an
reverse pulse anti-sulphitation unit on these (extralifepulse.com) it
stops sulphate build up which happens when batteries are left idle.

Never had to change a battery.
