how long idling to charge the battery?

When I was at school car batteries weren't a worry - cars had starting-handles. We had one of these lead / acid thingies (in a thick glass container) but it was for the wireless, and every three weeks or so it was my job to take it to the cycle shop to get it recharged so that we could keep up with who was winning the War.

As I fitted a new battery following the first heavy frost of winter I found myself wondering what was the last volume-produced car to have a starting handle.

Automatic Renaults kept them well into the 70s and they remained issue with 4 cylinder petrol landrovers. My 76 V8 Landrover has one but the

1989 110 has the hole but no dog on the crankshaft. mind the 4cylinder one started easily on the handle, the V8 need so much churning I wouldn't attempt it.

2.1x6=12.6

Are you speaking about a 3 cell battery?

No. All lead acid cells were said to be 2.2 when fully charged. So 13.2 for a 12 volt battery.

It was somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember "DB." saying something like:

Series III Landy, iwt; though it certainly had the hole in the bumper, I don't know if it had the dog on the crankshaft pulley - come to think of it, I've never actually encountered a S3 that had the starting handle still with it.

I would bet Ladas, Skodas, etc carried on with starting handles for much longer. You don't want to be stuck in the tundra with a dud battery.

The diesel had the dog on the crankshaft pulley and the one I used had the cranking handle. God only knows *how* it was meant to operate or who was expected to use it though; the diesel compression made it a little hard to operate...

Think that is the problem. Most modern engines would be too hard work to start with a handle.

Also sprach snipped-for-privacy@burnt.org.uk:-

It's for cranking it out of puddles. You take the glowplugs out and wind it out of the hole with the winding handle.

Lead-Lead batterys abyway, if you've got a leadcalcium battery it's more like 14V for 12cells :-)

It was somewhere around Barstow, on the edge of the desert, when the drugs began to take hold. I remember Guy King saying something like:

Blimey. Ice Cold In Saffron Walden.

Also sprach Grimly Curmudgeon :-

Cor there's a film I ain't seen for a while. Like Flight of the Phonics.

How does 'bollocks' sound? ;-)

On the most part correct, but the alternators output is not linear- as system voltage rises towards 13-13.5v output drastically reduces- otherwise you'd boil the battery.

So to go from say 75% to 100% charged takes alot longer than from 25-50%.

Tim..

like 'rowlocks' but starting with a 'b'. HTH

Somewhat irrelevant to a discussion of battery charging volatage:-) (OK 14V +-0.2V For /6cells/)

Ah. You've moved on to charging voltage now? ;-)

Fair point, I seem to get 12.8 as a consistent discharging voltage.
