Battery life

[feilding]

How long often do you change battery's on vehicles. I've just changed the batteries on my Discovery 2s,one in November and the other last week. Both were original batteries from new, so about 19 yrs on both.
They still showing nearly 13v but low on amp's .
both started ok but do fire up quicker on new batteries.

id be very happy you got 19yrs on a vehicles battery.
are you on about the charging volts or stationary engine off volts of the new batteries or old ones before you changed them ?>

Id be very happy if my batteries did 19 years

I am not disputing what you say but 19 years is a very long time
Have you had discovery from new?
Is there date stamp on battery
I thought I was doing well with 9 years
On Peugeot 307

Most car batteries these days don't seem to weigh as much as I remember. Be lucky to get 5-8 years out of them these days.

Battery voltage, engine off.

at 19yrs id be quite happy if they battery was still working at all.
ive got machines here with 10+ yr old batteries on but hardly ever used.

Used most days. Never failed to start ever, but got slow to fire up, but now instant fire up. Which I'm told was low amp's from battery not low voltage.

Our little Avant loader still has its original battery fitted from 2008.

It does depend on if the battery has been abused.
If it's allowed to be run flat or the machine is a bad starter it's going to significantly shorten the life of the battery.

Thats how batteries go its the cranking amps that ultimately make them fail. reading voltage is often not a true indicator

Battery’s should be changed as a pair imo.

Batteries on my JD 4755 only do 3 years then it needs a new pair.

Current battery on my deutz m620 is nearly 8 yr old so far. Original only lasted 2 yrs. But was replaced with a bigger amp hr model .

My JD 6420 was bought new in 2004 with the larger 154Ah battery. It still starts every time but I keep wondering when it will let me down. Probably when I'm in a hurry. I think 16 years is excellent for a battery and the tractor is brilliant as well. Only problem with it was the radiator went and took the cylinder head gasket with it. (I wasn't driving it at the time!)
