Battery puzzle

[Qman]

9 years is remarkable for a battery , my tractors eat the fudgein things

The battery on my JD 6420 is 16 years old and still starts the tractor. You ought to look after yours better!

What , give it a kiss every now and then ?

What u recommend?

If you have access to an ammeter clamp, try and see what current the battery is accepting when the engine is running - you should get 40A or so. If it's not taking that in, it’s probably knackered. I’d bet on the battery being dead anyway. Why not swap it out for one from a car/ truck and see what’s what?

Thanks for that MH, yes I had that with my Same Explorer when the earth strap corroded inside the crimp, cost me £40 if I remember for a 8" lead from Gwar Rhos!

But I reckon I have eliminated that because if I disconnect the battery and then connect the jump leads to the tractor battery connections the starter works, i.e. substituting the jump leads for the battery. That being so if there was a fault in the tractor leads/connections or elsewhere it still wouldn't start. Thats the puzzling thing, It seems that although the battery voltage is reasonable there inst enough energy to spin the starter.

I'm resigned to getting a new battery when I can find one.

If I’m reading it correctly you are still not eliminating the earth lead connection to tractor chassi. Where it bolts to the tractor. That’s where the jumplead from a bolt head to the connected battery comes in.

There is firm somewhere in north wales called Tayna who supply and deliver batteries

Hi Startinghandle

Tayna are in Abergele, I've not dealt with them. Used to deal with Manchester Batteries when I was in Colwyn Bay and they were in Abergele, ( now in Bodelwythan and called Manbat) and it was they whom I rang for advice yesterday without success, but will now try Tayna. Thanks

I would buy the biggest amperage Varta battery that will fit, as has been recommended look on the Tanya site which gives you all the details.

Yes kissing your battery is very important. Also I make sure that she gets some distilled water when she needs it and for a special treat on her birthday I give her a good charge with my ctec. https://www.ctek.com/uk/products/car/mxs-7-0-uk

My case5120 is 24 yrs old and on original battery,starter and alternator 9800 hours. Valtra Varta battery failed after three years. Must be luck of the draw

 

[Netherfield]

You really need to check the battery voltage while trying to start the tractor, voltmeter across the battery terminals, then try the same at the starter motor connected to where the main battery lead is and a good earth point on the motor, both readings should be the same, if not you've got bad connections.
You can be fooled and get a good voltage reading when no load, but voltage can drop quite a lot under load.
@Mursal usually comes and gives a master class at this point, but haven't seen a post for a while now.

Tayna have been my first port of call for batteries for several years now. Service has always been fantastic whenever I've spoken to them, with most deliveries arriving the next morning, even when ordered of an afternoon. Nobody has touched them on price either, when I've shopped round. Heartily recommended from me.

Went to Tayna Batteries today ( quite a business, much bigger and busier than I expected for a small town, on-line only, had to sit outside, order by phone!) anyway got my battery but because of Covid they were not performing load tests, so dint know the condition of my puzzle battery. Fitted battery and tractor starts on the button, so presume that my old battery's faulty despite its good voltage reading.

Thanks to all who chipped in with suggestions. Problem sorted, but not really diagnosed.

[Qman]

What brand of battery did you buy?

 

[SilliamWhale]

Got a battery on my 2003 land rover never been changed yet.

Sometimes its luck. A new battery is never a waste of money.

Halfords can be good for batteries and warranties with the trade card as well.

My valtra battery that failed was showing 12.7v on a cheap multimeter but on a proper load test nothing." A cell's f#cked" was the diagnoses. Just one of those things I'm afraid

 

[cyffylog]

It was an Exide, Premium EA 900, 88Ah, 580 A, as SAME specify, and the only decent make that Tayna offered. £73 inc VAT

Damn I thought our 06 plate jd6620 did well needing a replacement battery this year.

Didn't they have a Varta or a Bosch on their list?

For a lead acid battery - fully charged would be about 12.9v and fully discharged about 11.4v - the 1.5v is all the difference between a charged and flat battery. Check the voltage on your new battery to see the difference.
