Series 3 batteries

suspect my s3 battery is coming to the end of its life, seems to be struggling in the cold this year. no idea how old it is, was on the car when i got it around 2009.

always wondered if it was really big enough as it is only 50 ah cca isn't bad at 510 battery type 065. never had any problems before, even in colder winters

the one on the s1 is 70ah - type 069 - and has been replaced whilst i have had the car.

I would have thought the s3 diesel would need to be bigger because of heating the plugs.

according to the manual it should have a Unipart gby 2233 battery, assume this is an old code but can't find anything that says this is a modern replacement for that code.

is 50ah enough what do others have?

battery sites don't seem to have series landies listed so the closest being a 90 diesel have 100 ah and 1000 cca sounds a bit too much

suppose I could try the s1 battery out as it is currently wintering in the garage and probably won't come out till easter

Fit the biggest battery that will fit in.

I think my series had a 110 ah in it, I know it was huge.

thx chaps big un it is

Mines got a 96AH Commercial vehicle battery in it

seems everyone has a bigger one than me

Agree with that.
Just bought one recently, I measured the space and checked the terminal position then ordered a 100 AH Calcium type, its working a treat, only cost £60 with 4 year warranty and I took the old one to the scrap dealer who gave me a tenner for it, good result.

Biggest is best.

I even posted in that thread, forgotten all about it, thanks for the link, looks like I shall give a big hankook a try, interesting about the calcium technology and infrequent use

As long as your alternator is pushing out 14.2 volts or more that should not be a problem.

I bought a cheap LED voltage gauge and fitted it into the fuse box cover, shows between 14.2 and 14.6 V when running. Also tells me I have about 11.6 V when the defender has been standing for a few days, old battery was down around 9.4 V

think I shall go for that £60 hanook, measured the bay and there is enough room, can't grumble on the price, seems like good eating to me. checked voltage when engine running, my tester is a radioshack one so shows how old it is , can't remember when they withdrew from our shores, anyway alternator output high light is on which is supposed to be c15v so looks like I am good to go.

like the idea of having that voltage guage

Shouldn't drop much below 12.6 volts standing. Unless you have something coupled that is draining it. 11.6 is pretty low.

Measure up and be sure it fits, mine is a Defender so it may be slightly different from the S3.
Voltage gauge was easy to fit just cut a square hole in the fuse box cover and hook it into a supply which is live when the ignition is on, I added a small plug so I can take off the cover completely by Un plugging it.
Going for an upgrade this year I bought a small module which will display water temp, oil pressure, and battery voltage + displaying time

When I took delivery of the battery I put it on an intelegent charger and left it till the weekend, by which time it was showing full charge, when I fitted it on the vehicle the V meter read a fraction over 12v. Not much on my defender to drain it except the alarm and even the old battery could sustain that for more than a week, that battery was on its way out and even if I plugged the charger into it for a day, a few days later it showed <> 9.5v when I switched on the ignition.
After a few weeks the new one spins over the engine pretty quickly and shows around 11.6v when not used for a few days, makes me realise how bad the old one was.

I shall check the measurements again in the morning to be sure

I only get 13.2v when the engine is running. Having said that I havnt changed the lemon for a while.

Full calcium batteries need a much higher charge rate than lead antimony batteries. If they are not kept fully charged they can sulphate up and become useless. Can sometimes be recovered by charging at 15 volts + or higher for an extended period subject to electrolyte temperature. But a fully charged 12 volt battery should be no less than 12.6 volts after being allowed to stand for an extended period after charging. Suggest you get a better charger. If you don't sort something out you will ruin your new battery if you have not done already.

Got one of these in mine

Starts everytime, and will again once the compression issue is sorted
