Frosty Mornings wont start, New battery?

Keep having probs starting whenever there's a frost, The engine wont turn over. I've checked the starter motor and alternator their fine. Cables all seem secure & clean, So had the battery checked today, Again thats ok. I'm now thinking perhaps change the battery for a higher cca one. Currently on the car is a "Numax 096 72ah 680cca" I've seen an "Exide 067te 75ah 760cca" Will this make a difference or just be a waste of £89.

If it's a diesel, maybe the glow plugs are gone.....?

Glow plugs are gone by the sound of it,the awkward one is No4 behind F.I.P. pump but some Rover 400 L series engines only use 3 anyway, so just change 1,2 & 3 and see if it improves starting. Another few weeks and you will be ok anyway.

FFS he said the injun won't turn over - what's that got to do with glow plugs?

Is the starter turning but not the injun?
When you checked the connections, did that include the earths, specially the injun to chassis one?
Can you hear the starter solenoid clicking?

It's a td4. Starter motor just clicks. It seems like there's not enough power to turn the engine over. Only happens when it's cold. Had a jump start the other morning and it started ok. Thats why i had the battery checked, but was told it's ok. So now i'm thinking better battery might cure the problem. Just wondered what type of battery everyone else is using as regards the cca(cold cranking amps)

If your battery really is OK, then it's rating is fine. However, it does sound like a battery problem if it starts reliably when jumped and your certain that the charging circuit is OK.
How was the battery checked? Just the no-load voltage, or was it load tested?

I had this problem on my rangie,battery would be dead on a cold morning but after charging and testing the tester would say good battery,As treworgey says the battery you've got is the right sort of rating but sounds like its knackerd.I'd recharge it once more,fit it and test the vehicle for any current drains just incase.if theres nothing strange then get a new battery as it worked for me.

check the battery terminals are clean and tight. If it starts on a jump start, apart from the battery thats just about all it can be

Hi i had the same problem with an old cavalier turned out to be the starter motor

well i agree with the magority here battery may be fine on volts test but you need to load test. go to a good battery centre they`l do it for you.

I've had this exact same issue with my 2000 TD4.

Cold morning - you get in and click. nothing. Jump start is fine away you go. no problems once everything warmed up.

Change the battery! Its not holding charge overnight when its cold. Also there is extra demand on a cold morning if you have a FBH as it will try and power the glow plug in that too!

Swapped mine for an AC Delco one and (touch wood) no problems. It was -7 this morning here and started first time.

first thing is to determine if its a battery problem .ie- is it the correct rating how old is it and is it holding its charge ?,

cold weather reduces battery output ,and a cold engined demands more power to turn them over .

for less thasn £1oo you can get a good quality battery, and buy the high capacity one , you will then have eliminated one potential problem.

but if you can get a set of jumpleads and a jump start this will prove its the battery fore sure ,

a diesel engine needs to turning over fast to get the fuel to ignite, if its turning over slugish then you better just start praying ,,

Charged the battery up sunday night and it's started ok last 2 mornings (2 very cold mornings) so it seems like battery is slowing losing it's charge. I'll see how long it lasts before it fails to start.

you may have somthing slowly draining the battery , rear boot lamp or something similar ?

but most likley your battery is knackered

Spend a little more on an OPTIMA RED TOP, I did and never regretted it. You can get one from about £90 -£135 depending on where you go. ( 830 Cold Cranking Amps )

Just to close this thread: I fitted an Exide battery (75ah-760cca) and have'nt had any probs since, Last 2 mornings have been frosty but started ok. Looks like old battery could'nt handle the cold mornings. Thanks to all for info & replies.

use a jump lead to provide direct earth from bat neg terminal to eng block. may have a lazzy starter wi a duff armature. but did the bat have a drop test done, if not get that done first.

just as a point of note, if you have this problem, there is no point load testing the battery later on in the day, or especially once you've had the engine running. The load test has to be carried out in the same conditions you're trying to start in. So if its bloody cold in the morning and it won't start, try to test it then

Check out your earth, cold morning = more amps. jump start gives more amps.

There's no doubt it was the old battery at fault. New battery has been fine, No probs even on the very cold day's we've has recently. I think Optimus Prime has hit the nail on the head. I had the old battery tested when i'd driven to the tyre centre engine was warmed up and battery charged up from driving there. I'm not sure how old the battery was but it just could'nt crank the engine when it was very cold, So maybe a cell was on it's way out or acid not up to spec. Whatever it was dumping the battery has cured the problem. ATB.
