skmelrose Posted February 25, 2019 Share Posted February 25, 2019 HiHaving successfully removed and rebuilt the carbs on my 1992 HPC Vauxhall Red Top, I am now trying to sort out the battery. The car came with a lead acid unit intended for a lawn tractor with a rating of 350 cold cranking amps. There is no mention of capacity so when I look at Li-Ion options it is impossible to choose a size. The exiting battery is positioned under the carbs and is a total pig to get in and out so I am looking for a smaller unit.Antigravity suggested a unit that is 30 amp/hr and 800 CCA but it is the same size as the existing one. Demon-tweeks list Varleys ranging from 13 -20 Ah and 156-230 CCA as possible choices. In the end, I am looking for rating advice as I will have to source here in Canada.On a separate topic, I have discovered that the car has a LSD which is exciting but can anyone tell me what sort came with HPCs and what oil to use?As usual it is going down to -23C windchill tonight with the usual mix of snow, ice, gales and general winter pestilence but, one day, the snow will go, the roads will loose their frost heaves and the garage door will open again.As always, any advice will be much appreciated.

Kpcseven Posted February 26, 2019 Share Posted February 26, 2019 Odyssey PC680 should be widely available in Canada. Fits easily in space below the carbs, in and out without removing carbs. I have a 93 HPC Vauxhall on carbs and it fits without a problem.Ken Link to comment Share on other sites More sharing options...
Tazio Posted February 26, 2019 Share Posted February 26, 2019 The diffs would have been ZF Plate type, I use Castrol B373 in nine. Link to comment Share on other sites More sharing options...
Support Team Shaun_E Posted February 26, 2019 Support Team Share Posted February 26, 2019 Varley Redtop 15 should work nicely as well. Started my high compression K series easily and now my 2L Duratec. Link to comment Share on other sites More sharing options...
