Leisure batteries have plate designs more suited to deeper discharge at the cost of a reduced cold cranking current.

The term is meant to apply to batteries that are not necessarily deep discharge batteries but can still deliver a reasonable high current without causing the plates to collapse.

For that difference, leisure batteries can withstand lower discharges. A standard cranking battery can only really dispense around 50% of its total stored energy before experiencing irreversible degradations. A leisure battery that figure is more like 75~80%, and for deep discharge VRLAs that is around 90~95%.

So a 50Ah DD VRLA is actually able to deliver more 'useful' energy, without damage accumulation, than a 75Ah cranking battery. It is therefore lighter, charges more efficiently, and can still deliver useful electrical power at 'low' voltage. What is not to want for an EV battery?

There is no international standard that defines how a "leisure" battery is constructed, how many cycles to any particular DOD it must survive, nothing. Caveat Emptor

It's pointless buying a battery because it's "meant" to be of a particular construction, based on a bunch of marketing terms

I installed a Lucas Fusion from Tanya a year ago and chose it solely because it is an AGM type and so not flooded.
Why OEM EV's seem to get poor life from batteries is beyond me as they have a stressless life. Its not just Volt/Ampera's.
My other EV 12v aux car batteries sit permanently on float chargers when not in use, are only 20Ah yet seem to last years in this way.

I use three 12v Pb batteries on my converted Stiga ride on mower which has a Lynch motor. They are not treated well!
Over the years I have used deep discharge and flooded/non flooded of various types and sizes. The best have been standard flooded cheapies off the internet. These are unfortunately sealed and now failing. I think they are low on acid but cannot top them up as the damn lid is welded on.

So I agree with posts above that the term "Leisure" or "Deep Discharge" is a sales pitch.

The general consensus on this topic seems to be: get a Varta D52 AGM, if you want quality at a reasonable price or for an even lower price go for the Lucas Fusion LF027 AGM both are 12V 60Ah and a perfect fit. I previously posted my experiences with so called deep cycle leisure batteries and I am confident that either of the above will prove satisfactory for service in the Ampera or Volt.

After reading some of these posts, I have just replaced the 12v battery in my 2014 Ampera for which I have owned for the past two years. My commute is Gloucester to Swindon 35 miles each way. earlier this week, I had an amber fault light come on with a message stating unable to use internal combustion engine, the "Hold" mode was also unavailable and greyed out. I stopped in a layby switched off and then restarted the car. The amber engine warning light was still on but I was able to select "Hold" so drove the remaining distance 15 miles using the combustion engine. Charged the car at work and for the return journey the amber engine light remained on, but again I was able to select ". The very same thing happened the next time that I drove into to work (curiously I was also unable to select any DAB radio stations - coincidence ?) so on the way home pulled into Halfords Gloucester and had a Halfords branded AGM 027 Start Stop Battery fitted. it comes with a 5 year Guarantee. Latest - the engine warning light has now extinguished. I will keep you posted.

Many thanks to everyone who has contributed to this thread.

I replaced the original AC Delco battery in my 2012, 95000 mile Ampera today with the Lucas battery mail ordered from TAYNA. Thanks to your instructions, this was a simple job. The only minor complication was figuring out the clips holding the black box on the positive terminal.

I tried my local Vauxhall dealers for a replacement battery. I expressed so much surprise at the £225 price tag, the stores person offered it to me at £185 trade. But I went for the Lucas battery from Tayna, which cost £97.97 inc P&P.

I've owned the car since 64,000 miles. Most of my driving is a 30 miles commute, with a recharge at either end of the journey. Recently, when we have done long journeys which exhausted the drive battery, we would be braced for some craziness or other when we try to start up again. I started using "Mountain Mode" to retain some charge. Hopefully that's all behind us now.

This has been a very helpful thread, which I thought I'd provide a later update. My Ampera (2014/64 reg) has recently started showing some eccentic behaviours, particularly losing DAB stuff then a couple of days ago threw a steering lock error. I remembered seeing such odd problems associated with battery aging and thought it must be time to act. Following all the info on here I ultimately bought a Yuasa YBX9000 AGM battery, same 027 spec but available off the shelf from my local SAS Autoparts, an excellent local (northern) supplier. It cost £126.70, so broadly similar to the Varta delivered from Tanya but in stock 5 mins from home.
If anyone is interested in this option, the price includes delivery (although I collected it). The web site price is £253.39 but offers a 50% discount! You can find it here https://www.partsforallcars.com/za042695
I followed the fitting instructions from this post with only one minor hitch. Right at the start it omits to mention that you have to remove the whole boot floor (which just clips & velcros out) to remove the tray to get access to the battery. Taking it very steadily (and taking photos at every step: I'll do something with them shortly) the whole process was about half an hour.
As I anticipated the car was still running on the original GM battery which would seem to be something of a surprise given it was probably manufactured in 2013, so maybe I have been lucky that it has lasted this long. I wonder if it might be because normally the car is left plugged in when parked at home. This was my understanding (and reinforced by some more recent research) that the Ampera is designed to be left plugged in whereas some other types are best not.

I suspect that if it was a GM branded battery then it has already been changed in the vehicle's life. The original factory fitted ones were AC Delco. I went to change mine, also as a precautionary measure, and found out then it had been changed to a GM branded one. I had reported seeing a lot of error messages once just before the car was due for a service. I was told that the battery was fully charged overnight by the garage but I suspect that someone had replaced it and I was never charged for it, or maybe they put it through as warranty. Every time my car was at home it was plugged in and for over the last half of the time it was parked charging near work for half day.

Thanks for the comment. That's a really interesting thought, because I did wonder why it said Made in EU. I've just been to have a look at it to see if there's any evidence of age (given that my dealer has never said anything about a replacement) and found one of those date moulding pointers on the base which says 10/13. Makes me suspect it was fitted in the car when I bought it, perhaps replaced because of an issue with the original.

I replaced mine at over 7 years old and I had owned it from new. Sometimes the original figment exceeds expectations. (2012 model)
My daughter who has taken ownership is now having trouble with the new one, purely because of lockdown and not being turned on for ages (even though plugged in) the problem started when the supply was off to the EVSE inadvertently. That model does not maintain the 12v state of charge from the traction battery unless the vehicle is in ready or is charging. She got it recovered and I am monitoring via OVMS to warn her when the volts are dropping! It looks like it has recovered satisfactorily.

I replaced mine last year as it was starting to play up. Lockdown had completely killed it so replaced again today. Pleasantly surprised that nothing else seems adversely affected - nothing seized, brake corrosion cleaned up after a run, even the creaky front end seems to have gone away!

Please don't throw away discharged lead acid batteries. Get a good charger and desulphate them. It is extremely unlikely that any battery less than 5 years old needs to be replaced, and just adds to remanufacturing costs and wasted plastic and energy.
