ianmayco68 Posted November 30, 2019 Share Posted November 30, 2019 Hi all , I’ve been looking for a new battery and came across this one on Tayna batteries , https://www.tayna.co.uk/car-batteries/4x4/c31-1000/ which seems like a good price but I’m at a bit of a loss as to what some of the figures mean . I know cold cranking amps are the amount of power available at start up and the AH is the capacity of the battery but what’s the difference between CCA(en) and CCA (sae) ? and what the difference between capacity (c20) and capacity (c100) ? any help much appreciated as always cheers Ian Quote Link to comment Share on other sites More sharing options...
TSD Posted November 30, 2019 Share Posted November 30, 2019 The two CCA figures refer to the Cold Cranking Amps figure measured following different standards - SAE being the American standard, and EN the European one. Which one you choose to pay attention to doesn't really matter, as long as you use the same one for each battery you compare. Likewise the Ah figures can be measured at the 20h rate or 100h rate - that is, draw 1/20th of the Ah capacity for 20h, or 1/100th of the capacity for 100h. Because batteries aren't 100% efficient, and get worse at higher currents, the capacity looks a little better measured at 100h rate. You might infer something about the quality of the battery from how close the two number are if you have them both for the same battery, but its never just that simple. For typical lead-acid starter batteries, once you've met the CCA and Ah specs you've chosen, I'd choose the heaviest one in my price range. Lead is expensive, and heavy, and more of it tends to make a better battery. Again, nothing is ever really that simple, but it's a good guide. 4 Quote Link to comment Share on other sites More sharing options...

TSD Posted November 30, 2019 Share Posted November 30, 2019 Just for completeness, Yuasa has a decent guide on the meaning of the various battery specs and how they compare here. For CCA, that's as much detail as I've seen on the measurement procedure without paying the ransom required to obtain copies of the standards.

Retroanaconda Posted December 1, 2019 Share Posted December 1, 2019 I replaced the battery in my 90 in winter of 2008/2009 when the one it came with died. I went to the local auto electrics place and bought the biggest and heaviest one that would fit in the battery box. 11 years and 230,000 miles later it’s still going strong, so when it does die I’m going to do the same thing! Agricultural suppliers or any decent motor factors should have a range of batteries if no auto electricians nearby. 1 Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted December 1, 2019 Author Share Posted December 1, 2019 Nice one TSD ,I did come across that one when searching online , I’d already read a few by the time I got to that one and thought it was just a basic explanation like the others I’d read should have read it all .

ianmayco68 Posted December 1, 2019 Author Share Posted December 1, 2019 (edited) Cheers James , there’s a tractor place down the road and we have a Halfords which I have a trade card for , never really thought about the tractor place I would imagine they sell really HD batteries and good quality ones as well being as they are for tractors and farmers who really do like value for money . I’ve been thinking of moving the starter battery into the engine bay , I’m moving the washer bottle as I’ve brought an under the wing jobbie so I have that space , but I’m unsure if it is to close to the turbo? I can make the tray to fit in where the old washer bottle went and utilise the existing brackets .

Bowie69 Posted December 1, 2019 Share Posted December 1, 2019 A simple heat shield should be enough for a battery near a turbo. Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted December 1, 2019 Author Share Posted December 1, 2019 Had a quick measure today and as it’s a 200tdi I don’t think there’s enough room for a decent sized battery unless I spend mega money on one. Quote Link to comment Share on other sites More sharing options...
western Posted December 1, 2019 Share Posted December 1, 2019 got 2 of these in my '89 110's batt bay, long side to long side, its tight but they fit. https://www.halfords.com/motoring/bulbs-blades-batteries/car-batteries/yuasa--hsb019-silver-12v-car-battery-5-year-guarantee Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted December 1, 2019 Author Share Posted December 1, 2019 I’d looked at them western as I’d seen you’d used them and said they were good, also I’ve got a trade card which helps , idea was move the washer bottle under the wing as in the td5’s (already got the bottle) , then fit the starter battery in the engine bay and 2 leisure bats under passenger seat with the split charge relay and a fuse box which would mean I can fit the Eberspächer under drivers seat , but I don’t think there is enough room in the engine bay unless I can find a big battery spec in a small footprint which would probably mean spending a fortune . Smallest I’ve found so far is a Odessy pc1750 which was £300 and I’m trying to do this as cheaply as possible. Quote Link to comment Share on other sites More sharing options...
western Posted December 1, 2019 Share Posted December 1, 2019 Where the washer bottle sits at top of the inner arch doesn't leave much space above the damper turret & heater unit casing. but I'm sure you'll sort a suitable mounting for the start battery.

ianmayco68 Posted December 1, 2019 Author Share Posted December 1, 2019 No there’s not much room there on a 200tdi less than I thought there would be . Quote Link to comment Share on other sites More sharing options...
Eightpot Posted December 2, 2019 Share Posted December 2, 2019 The Numax batteries sold at Tayna are very good, been using them on various vehicles for 10 years or so - still got ones from 10 years ago too. they do a 110ah one for about £89 2 Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted December 6, 2019 Author Share Posted December 6, 2019 Cheers all , I’ve come to the conclusion after looking at the specs of many makes of batteries that most are made in the same factory and the only difference is the name and casing as they are all the same physical size with the same capacity and same cranking amps from multiple brands . Whats peoples thoughts on Exide premium batteries as I can get one 1000ah 900 cca for £70 of Ebay? Quote Link to comment Share on other sites More sharing options...
Anderzander Posted December 6, 2019 Share Posted December 6, 2019 I’ve been looking for a high CCA but small battery for the 80 - it only seems to be pointing towards a red top - anyone seen any alternatives? Dimension wise It needs to be within: 300L 200w 180h Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted December 6, 2019 Author Share Posted December 6, 2019 That’s the only one I could find Anderzander, I was looking to relocate the starter battery to the engine bay . Quote Link to comment Share on other sites More sharing options...
Anderzander Posted December 6, 2019 Share Posted December 6, 2019 Hmmmm. Thanks Ian. I’m not averse to paying for one - as there seem to be far far more positive reviews of them than not. So I think I will end up down that route. At the moment I have a SuperBatt, Silver 9000. Which seems good in everything except CCA. If I leave it a few days and we have a hard frost it can struggle to turn over the 200 despite having a supposedly high CCA figure. It also has some credible bad reviews about varied performance below the stated specs. Quote Link to comment Share on other sites More sharing options...
ianmayco68 Posted December 6, 2019 Author Share Posted December 6, 2019 I’ve read a few reviews of the red tops not being as good as they used to be , and the lower capacity was putting me off but then you read of people travelling the world with them fitted and the specs being okay , Odessy do a smaller one but they’re £300 and you only get a 2yr warranty . 1 Quote Link to comment Share on other sites More sharing options...
Snagger Posted December 7, 2019 Share Posted December 7, 2019 I found Banner batteries to have very good reliability, even in that -15 or so cold snap a few years back, and very good longevity at over 10years and counting. Good brands barely last 3 years here in the Gulf, but I don’t know it that’s because of modern vehicle electronics sapping power, the temperatures, or just battery quality. Probably “all of the above”... Quote Link to comment Share on other sites More sharing options...

BogMonster Posted December 7, 2019 Share Posted December 7, 2019 Yuasa batteries are excellent in my experience and last for years in other applications. I've never tried one in a Defender but I am about to change that Quote Link to comment Share on other sites More sharing options...
