Wouldn't the current be the issue.

I don't understand what I'm talking about, naturally, but google tells me that my stupid car has a battery with something called CCA of 500 whereas the landrover battery has a CCA of 800 to 1,000.

I have no idea what any of this means.

Oh dear! Where to begin?

CCA equals cold cranking amperes. The point is that batteries need to be able to deliver a certain amount of current in order to run the starter motor effectively. The battery is just a chemical reaction, and this becomes less effective in the cold. Consequently, one of the measures of how good a battery is is how much current it can provide at a very low temperature, normally calculated at -18°C. This is very important for people living in the north of America, but less important in this country.

As far as I can tell from Google, Land Rover's use exactly the same voltage as every other car in this country. However, they have quite a big diesel engine, which takes a lot of turning over to get it started, apparently.

One of the other measures of batteries is capacity, which is in units of ampere hours. A typical car battery has a capacity of around 50 A hours, which in theory means it can provide 1 amp for 50 hours or 50 A for one hour. Typically, a car starter motor needs something in the region of 500 A, so it will drain the battery in around 5 min theoretically, and in practice rather sooner than that.

So, Land Rover owners tend to fit larger batteries, i.e. ones with more capacity, But operating at the standard 12 volts. They also use batteries with a higher CCA. This copes with the fact that they tend to leave the car somewhere cold overnight and the big diesel engine. Also, some of these cars have electric winches, and I imagine that some of them are only used for short journeys, so the battery does not get charged all that much.

I cannot see any reason why jumpstarting another car from a Land Rover would fry the electrics, assuming that both cars are 12 V and the jump leads are connected correctly.

I am not sure you want to know all that, but there you are.

Barbara, wife of Edward Hastings (soldier) & widow of Cave.

I think this is Barbara Devereux? She was formerly married to Edward Cave

OH has a cousin who was contacted by someone who turned out to be the offspring of their father's first wife. After validating story ( cousin didn't know that their mother was not the only wife and all parents now dead) they met up.

First meeting was a success, exchanged photos and memories and stories between newly discovered half-siblings.

Second meeting turned sour. Half-siblings complained that mutual father leaving for wife 2 left wife 1 and children in financial difficulty and they felt these newly discovered half-siblings should compensate them to equal the financial disparity!

There was no third meeting.

That's the one. She was apparently previously married to Mr Cayce (sorry can't recall first name), but misspelt as Cave and Caue which is what I was saying about weird spelling.

There's a rumoured third marriage after these, which I think is another internet legend with nothing based in truth. She has the same name as someone else, but in order for it to be her, she would have to have time travelled. Still, people should never let that get in the way of having royalty in their chart, eh?

Morning Pastures, I now think you are right, having said that I didn't think you were yesterday,

A common occurrence... most people just never admit it

Well, I have always been told by lr people not to, but if its really ok, next time you need a start if the lr working I'll volunteer it

I might actually check at some point what battery/ batteries are in it, just so I know.


I think a key thing with old defenders is they rarely come as it says on the new brochures. My series three had an engine change at some point, finding non standard is pretty standard in defenders. It's not just winches that get attached either, though I think they probably are one of the heavier duty attachments. So e things I have seen though in working vehicles operate of separate batteries in their own independent 'loop'.

I always follow the garage advice over things like this, because I don't pretend to understand it and guess they know more about it than me! So if they tell me not to jump start cars I feel they have a reason to say that...especially as its in their interest to get me to buy a battery sooner.


That said, I am also fairly sure I might have charged my battery with a charger at home in the past......and I don't remember buying a different one for the lr, which would suggest its all the same.

On another matter, have all NPs re-set their Evernote passwords?

Yes and I tweeted about it yesterday lunchtime. I've four accounts with them.

I don't know what Evernote is.


We painted a (IMO) ugly piece of furniture dh inherited with plans to put it in the bathroom when it's done this year. But now we think its too big so we are rearranging our room to put in in their because we both quite like it now.

Do you mind if I ask who says it was a spelling mistake & should be Cayce?
Yes, spelling mistakes or phonetic spellings are frequent in genealogy but they're, sadly, also widely used to justify connections that just aren't correct.
The references I've found to Barbara say Cave (Debrett's etc.)
Of course, they could be wrong. Even in the Visitations families could concoct their heritage but they would normally opt for the more prestigious connection if making up their lines - nothing changes does it? :rotfl:
