Adrian Posted April 18, 2018 Report Share Posted April 18, 2018 Hi all probably another silly question but I have a brand new Yaris battery doing nothing in the garage same size, just 440a rather than 420a. Is that ok or will things start to fry? Thanks Adrian Link to comment Share on other sites More sharing options...
Anglefire Posted April 18, 2018 Report Share Posted April 18, 2018 If it fits it will be fine. There are pretty much only 3 things regarding batteries. Voltage CCA (cold cranking amps) capacity. As long as the voltage is right (nominally 12v ) then it will fry nothing. If the cca is too low then it can struggle to turn the engine over - but tbh with petrol classics it’s not that relevant as they don’t need much to turn over. Capacity is again almost irrelevant as that is just the ability to have some storage for multiple starts etc. And largely governed by the physical size of the thing. 1 Link to comment Share on other sites More sharing options...
Anglefire Posted May 1, 2018 Report Share Posted May 1, 2018 Actually, I've just looked more closely - and the biggest thing to worry about is getting the wiring to fit - the posts look to be the other way around! Link to comment Share on other sites More sharing options...
dougbgt6 Posted May 1, 2018 Report Share Posted May 1, 2018 The blue one would be the better fit, -ve to the earth strap, so battery posts nearest the bulk head. The red one would have to be mounted the other way round posts at the front, problem then is the battery clamp shorting the posts. Doug Link to comment Share on other sites More sharing options...
Anglefire Posted May 1, 2018 Report Share Posted May 1, 2018 My battery is posts to the outside - not had an issue - and in fact having posts to the bulk head would concern me with the clamp shorting the battery out? Link to comment Share on other sites More sharing options...
Anglefire Posted May 1, 2018 Report Share Posted May 1, 2018 Or does the clamp go the other way? Also spot the missing starter Link to comment Share on other sites More sharing options...
dougbgt6 Posted May 2, 2018 Report Share Posted May 2, 2018 Mark, Yes, clamp on the front. Never considered you could put it on the back. Is it stable? I suppose yes, if you've done it. You can fail the MOT for no battery clamp. Doug Link to comment Share on other sites More sharing options...
Anglefire Posted May 3, 2018 Report Share Posted May 3, 2018 It was like that when I bought it nearly 2 years ago. Never have it a thought tbh. But seems secure enough ? Link to comment Share on other sites More sharing options...
Anglefire Posted May 3, 2018 Report Share Posted May 3, 2018 But it might explain why the rubber trim on the mud guard is missing and when fitted clatters the battery cables. ? Link to comment Share on other sites More sharing options...
