Tayna EA1000 battery with Start Stop?

Just ordered this for my MY2015 D4 with Start Stop (as recommended on Tayna's ebay site), only to find the battery says unsuitable for start stop!!

Quite why they're recommending it I don't know. Anyway, does it really matter, is there much difference??

Cheers

Main difference is that it is not an AGM battery.

Thanks, but in reality does it make any difference?

My disco has eaten 2 genuine land rover batteries so far, it isn't 4 years old yet. Are AGM batteries not designed to last more than a couple of years?

Three years seems to be about the limit, regular use of a Ctek may help to keep them going a bit longer.

You would be better off with an AGM battery, even before Start Stop, the D4 was using an AGM battery to cope with the D4’s power needs.

The CCF must be set to the correct battery type and size, as AGM by default on D4 the wet cell battery will never be charged to full capacity this will lead premature failure and highly unlikely the ss will not work, the AGM batteries are far superior to wet cell.
Without looking I don’t think there is in fact a setting for a wet cell in the D4 CCF.
Only time a wet cell can be fitted is short term to get you mobile. The charging strategy of a Wet cell is entirely different to an AGM, particularly on first start up.
Check the CCF, if it has a wet cell setting and is set to that it could be the cause of your batteries failing, for maximum life use a smart charger regularly to keep the battery fully charged.
The D4 SS has a very good battery tester it is the SS itself as this will not work if the battery charge or capacity is low Thumbs Up

Thanks, anyone near Hartland, Bideford, North Devon with the kit to check the CCF?

My understanding is that when batteries are replaced you need a Battery Management System reset which can be done with a diagnostic tool at home (IID). Was this done when you last changed your battery?
I’m wondering whether the batteries are failing because of the type of motoring you do. Do you do mostly short journeys? Is you car left standing for days between driving? If so using a battery charger to top up the battery on a regular basis (once every couple of weeks) will help extend it’s life.
Good luck resolving
Cheers

Sorry, I didn't reply. LR changed the previous battery 2 yrs ago, she has long runs but has been sitting for some days without a run, but I have been charging her. This time I went away for 4 weeks & it killed the battery, it was fully charged before I left.

I've now changed the battery for the proper type, it's running OK at the moment.

You don’t say what you are charging it with! Also have you any added extras or electrical mods fitted?- these are the first thing to check as they can be drawing current when the car has “gone to sleep”, typical example is the fridge on a D3, leave it switched on and you will have a flat battery.

No extras fitted that should be using power, I charge using a standard old fashioned type car battery charger, sometimes charging both batteries.

From the article referred to in philm's helpful post:-

Quote:
An AGM battery is designed to be charged slow and low, and overcharging it can kill the battery itself. So, a normal battery charger can’t be used to charge an absorbent glass mat battery.

Most of the AGM battery chargers are equipped with microprocessors that collect information from the power cell to see its current charge status and to adjust the voltage and current accordingly.

However, there some battery chargers today designed to charge both lead-acid and AGM types of battery by having charging mode selection feature.


I use a number of CETEK chargers, but don't stint & buy one of the smaller ones; you will regret it. I have three as I needed two, but the first which I bought was not up to the job.

Despite this thread:-

https://www.disco3.co.uk/forum/ctek-charge...p;start=15 I'm still using my CETEKs !

I do think that the CETEK Battery Sense might be worth considering although I haven't bought one:-

https://www.ctek.com/products/vehicle/ctx-battery-sense

but read the reviews first some love it, some hate it:-

The maximum voltage a AGM battery can take is 13.8volts old conventional chargers can charge at anything up to 16volts when on a fast charge. This is why the CCF has to be set to the correct battery type and size, also charging with a conventional charger whilst the battery is still on the car can do endless damage to modules that are not designed to operate at such high voltage.

Thanks, I'll take a look at the chargers. I never remove the battery/terminals to charge, if the alternator can charge it without damage, so can an ordinary charger in my opinion. But I always place the clips on first, then turn on so as not to create a surge/spark.

This replacement AGM battery from Tayna I'm a bit suspicious of. It has obviously been fitted before as the terminals were dirty, it was also down on charge. I charged it for 12 hours, but it was still putting 2A into it... Is this normal for these batteries does anyone know?

Cheers
