Having done a couple of long runs the next day the battery voltage reads 12.3 volts ( my car has stop/start). Think it is the original Varta 800 amp 80amph battery with an LR stamp on it and its 4 years old.

From what I have read its is not in the best or worst condition but about half way according to my volt meter. No problem with alternator charging around 14+ volt approx.

Is it about time to replace it ???although looks as if the stop/start system is working ok now which it didn't before due to short trips causing battery drain.
I have had a look at the Varta F21 battery which seems to be the replacement . Any advice most welcome. Would changing it have any affect on the cars settings once disconnected and reconnected Ex 2010 Freelander2 GS-e Diesel manual Silver owner

Realspeed, a check of the servicing schedule (obviously) confirms the battery is not required to be replaced or refurbished at all. Leaving me to assume it is to be done on condition only. As it is working - and working well, I would be inclined to leave it until it shows evidence of letting you down. By all means, keep it charged - maybe a CTEK charger would be a good investment? (I have one I use for my caravan "leisure" battery). If you look below, my maxim is "If it's working, don't fix it"

Thank for the reply. The car is main dealer serviced every year irrespective of mileage so the battery should be ok.
i can't charge it up as I am in the process of moving house and my chargers are in store. Had no problems starting the car only had no stop/start before where I lived as it only did short journeys.

Just to give you some encouragement - my previous 08 SE was still on its original battery at 103,000 miles when I sold it in February (nearly six years old). Ok, it was not a stop/start model, but your battery is uprated to accommodate that.

Realspeed,
It's impossible to forecast how long a battery will last. Some can give many years of good service; I've know some to last 15 years and I've known some to fail a cell within a few months..
Problem is, you could buy a new battery that might possibly not last as long as your current (no pun intended) one.
If your battery is giving you no problems, I'd be inclined to keep it.

Re original post, you can disconnect and reconnect the battery without problem. It will reset your trip meter to zero and you will also need to recalibrate the electric windows - the procedure is in the handbook. Ex AA Series III LWB Safari - Gone

A smart charger is a good idea since i got mine every now and again i put mine on a conditioning charge which pulses to break up any deposits then slow and fast charges in a cycle until complete,my battery is as old as the car 7 years and is good and strong. I got mine Ring brand from Costco about £25,C-Tec are very good and Lidl and Aldi have one now and again about £15,people say it is identical to the C-Tec but much cheaper.

If your battery has a voltage of 12.3V after a run it is only charged to about 70% of it's capacity, should comfortably achieve 12.6V+ anything up to 12.85V with surface charge is not uncommon which will dissipate over a couple of days.
Whilst the battery is now not capable of full charge 70% should be more than adequate until a serious cold spell of weather occurs, even then it may start your car....just. Cold temperatures also have the effect of dropping battery voltage even further, typically 0.1 to 0.2V overnight.
It really depends how reliable you want your car to be particularly in winter, I personally would renew the battery given the minimal cost involved but as indicated above some batteries in cars just keep going for a few years more than they should.
My daughters Freelander has the original battery from 2007 which works perfectly, even though I keep telling her to change it. She will get caught out however one cold morning when no doubt I will be expected to sort it.

all advice thankfully received. The varta f21 battery is around the £130 mark with a 3 year guaranteed life span which I don't understand as surely it depends on the amount of use it gets.I also don't know the amount of abuse it had being owned from new for a year by a previous owned who had a tow bar attached although it had only done 7000 niles when I bought it. The previous owner apparently wanted to go for an HSE version instead Ex 2010 Freelander2 GS-e Diesel manual Silver owner

Unless you have a calibrated voltmeter I wouldn't place too much faith in your voltage readings anyway.

Out of interest I just measured the voltage of my own battery with two different (non-calibrated) digital multimeters. One read 11.99v, the other 12.14v - a not insignificant difference for current purposes. Are either of them correct? Who knows!

Both are giving low readings, but hopefully this is simply because the car has been standing for a week. I'll be doing a couple of longish runs tomorrow, so I'll check it again then. Whatever, the car starts easily enough, so I won't be replacing the battery just yet.

If you do decide to buy a battery Eurocarparts normally have some sort of discount going.
Remember that the stop-start vehicles have a different (and more expensive) type of battery. The two types are NOT interchangeable. Ex AA Series III LWB Safari - Gone

Yes I did find out it needs an AGM battery for my car which the Varta F21 battery is. Took some finding to get the right amp and CCA. Its the same as in the car provided by LR Ex 2010 Freelander2 GS-e Diesel manual Silver owner

My stop/start has stopped working, I think I need a new battery. 130 quid for an AGM battery is a good price. I was going to replace mine this winter but then we didn't really have a winter. The car starts fine. Last winter when it was really cold the car started but was sluggish to turn over.

I measured my battery voltage after the car had been stood for a day, the voltage was 12.1v. I might get a decent charger, I use the one at work, its a smart charger but doesn't do a conditioning charge. After 20 minutes of charging the charger says my battery is fully charged. Black MY2013 SD4 GS Auto, Wood Company Armrest, Freel2 sticker.

Hi. My battery died yesterday. It is a freelander 2 HSE MY2010.
I parked the car with the radio turned on for 5 minutes and after that the car didn´t start anymore.
The battery was hot even after hours removed from the car (I guess it had a short circuit inside).
Since my car has not the Start/Stop system, the battery is a flooded type with 80Ah but here in my country we don´t have this kind of battery available.
I had to replace with an AGM battery with 75Ah and it is working fine now.
On the next days I will connect SDD software and see if there is an easy way to tell the ECU that now I´m using another type of battery so that the charger use the correct calibration.
Regards.
