mikeyb Posted January 8, 2007 Share Posted January 8, 2007 I need a new battery for the PI - currently got Colin's tractor battery in her - too big and he wants it back! What's the standard model number of battery fitted and given the space available, has anyone fitted a higher powered replacement?RgdsMike! Link to comment Share on other sites More sharing options...
valencia1 Posted January 8, 2007 Share Posted January 8, 2007 i suspect the original would have been a 57amp/hr 9 plate, so take the physical measurements to your supplier or your old battery as a pattern and see what they have, no doubt the modern battery will pack more punch for the same sizeregards, bryan Link to comment Share on other sites More sharing options...

mikeyb Posted January 8, 2007 Author Share Posted January 8, 2007 thank you, but what I was actually after is the generic battery model code as labelled on the case of most batts somewhere! It will be three digits - something like 075 or 069. I know the codes for Dollies, Spitfires and Range Rovers but have never had saloons until recently.Gertie has an 031 which would seem to be a 70amp/hr, but I don't know if that's the correct spec. Interesting that the original Mk1 batt was only 57amp/hr, perhaps the 70amp/hr one is what I need! The PI has a standard starter so I want to get as powerful one as I can!

Richard B Posted January 8, 2007 Share Posted January 8, 2007 Owning a few PI's, I'd say find the most powerful one that will fit. Batteries have got more compact but you want at least 400 AH for cranking.Personally on a PI, I go for really sorting the electrics.New heavy duty battery leads with soldered terminals (live & earth)A relay to switch a good electrical feed to the pump (rather than having the pump fed through the ignition switch).On the Spitfire I then added a Nippon Denzo.Sorry if I've thread drifted. But it's a real strain on the system starting a PI; Hi compression cranking, fuel injection pump and electric ignition. Link to comment Share on other sites More sharing options...
mikeyb Posted January 8, 2007 Author Share Posted January 8, 2007 Thank you Richard - you haven't thread drifted at all - You have confirmed my suspicions and highlighted the very reason why I hadn't just gone out and bought a cheap, standard battery. You've raised some simple, valid and important points here. Whilst I want to avoid going down the hi-torque route if I can get away with it, the other options are definitely worth looking at.Did you put the hi-torque on the Spit because you couldn't fit a 400Ah batt in the batt box?400Ah is also considerably higher than I would have realised! Regarding the relay/pump circuits, did you leave the bump cut out switch in the main power line or did you convert it to the relay switching supply line? I would think that is a potential voltage dropper? Link to comment Share on other sites More sharing options...
GTRoger Posted January 8, 2007 Share Posted January 8, 2007 Just measure the space you've got and take the biggest battery you can get. The more amps the better. Link to comment Share on other sites More sharing options...

Richard B Posted January 9, 2007 Share Posted January 9, 2007 The Spitfire got the hi-Torque starter as the PI Pre-Engaged Lucas starter would not fit with the 6-3-1 (Mike the Pipe - GTVEO prototype) and the GT6 starter would just burn out.The inertia switch switches the relay, not in line with the main feed, as you say you get a voltage drop across this switch. I ran a new cable to the boot on the PI saloon, not sure if that was needed, as the gauge is quite heavy on the original. For the Nippon-Denzo conversion it is not too expensive if you shop around, I bought a starter off of eBay and Canley Classics does a reasonable priced conversion kit. I think it set me back about £75 in total.For some reason people look suprised when I say 'I solder my battery lead terminals with a blow torch'. :) Still we all have our quirks.Most auto-electrical suppliers can provide HD battery cable.

valencia1 Posted January 9, 2007 Share Posted January 9, 2007 i take you mean your battery clamps, i was always taught to keep naked flames away from lead acid batteries! Link to comment Share on other sites More sharing options...
Richard B Posted January 9, 2007 Share Posted January 9, 2007 Sorry yes, soldered Battery clamps & Ring terminals. Usually use 400amp cables as well.Davesideways would probably complain about slowing the car down with the excess weight. :) Link to comment Share on other sites More sharing options...
valencia1 Posted January 9, 2007 Share Posted January 9, 2007 that's ok, quite agree they should be soldered. Link to comment Share on other sites More sharing options...
valencia1 Posted January 9, 2007 Share Posted January 9, 2007 anyone use those quick release clamps by the way, any problems with them working loose etc.,had some in the shed for a while but never got round to fitting one. Link to comment Share on other sites More sharing options...
Tim Bancroft Posted January 9, 2007 Share Posted January 9, 2007 All my cars have a dis-car-nect fitted- nice and easy and a reasonable security measure. Link to comment Share on other sites More sharing options...
mikeyb Posted January 9, 2007 Author Share Posted January 9, 2007 Most of mine have dis-car-nects fitted too. I persuaded them to advertise in the club mag when I was on the committee of CTE about 15 years ago and we bought a load through the club at a hefty discount! I have some quick release ones stashed somewhere too (from the same people) but I havn't seen em since I bought em years ago - probably up the loft somewhere!I wouldn't be without a means of fast emergency battery disconnection - if your wiring loom's going up in smoke, then you don't wanna be in the boot looking for a spanner!

mikeyb Posted January 10, 2007 Author Share Posted January 10, 2007 Battery homework so far:- Model Ahr/Cold Cranking Amps031 70/540 - wrong pin config065 55/450 - wrong pin config069 68/505 - correct pin config071 52/390 - correct pin config072 70/550 - correct pin config075 60/525 - wrong pin config096 72/675 - wrong pin configThere's no significant diff in price between any of them, so look like I need an 096 with the pins reversed ideally!If not, then an 072 looks to be then next best bet - Diesel Discovery.Thanks to all of you for your input,RgdsMike!

Richard B Posted January 10, 2007 Share Posted January 10, 2007 If you sort out the other things (cables and relay the pump) then you should be fine with a 69 ;D or an 072 but that does not sound as good ;) Link to comment Share on other sites More sharing options...
thescrapman Posted January 10, 2007 Share Posted January 10, 2007 The 069 is the back to front 075 checking the cars outside.The 065's I have were the cheap ones from Partco.CheersColin Link to comment Share on other sites More sharing options...
mikeyb Posted January 10, 2007 Author Share Posted January 10, 2007 How cheap was cheap Col? Looking at about 50 quid for the 072.72 looks to have more go, but I've always been a sucker for a 69! ;D Link to comment Share on other sites More sharing options...

mikeyb Posted January 12, 2007 Author Share Posted January 12, 2007 Sorted! 086 battery purchased and fitted. 72Ah and 680 Cold Cranking Amps and actually smaller than the Range Rover battery! It's actually an 096 with the pos/neg poles reversed - just what I wanted! Link to comment Share on other sites More sharing options...
