Hi guys

just took the battery out of my RR P38 can anyone tell what size battery should be in there it is a 70Ah
i would of thought something like a 120Ah should be about right ??/

What battery are you using ??
 
CCA's are more important than A/h..get a battery that fits in the box with the highest CCA's you can.
 
If its a diesel thats not enough...i've got 800cca battery in a 90..i was looking for a few more but needed one quick..
 
No it,s petrol 4.6 / LPG so you dont think 570cca is enough
it was ok in the summer but in the winter i had to keep jump start it every couple of weeks
 
Thats cos in the cold..you need cca's..cold cranking amps..the more the better..in the summer you dont.
 
Yeps..A/h is of secondary importance..although still important..go for a balnce of the two..but for a big engine like that you need a lot of amps going in at start up in winter..i'm a tratter driver but i'd suggest at least 700cca and pref more...someones put a cheap battery in...be prepared to spend £100 on a good 'un.
 
SHOP AROUND!!

Theres zillions of places and prices vary...some of the internet next day free delivery are good...but measure your box to make sure it fits!!
 
Go to an agricultural supplier and get a tractor battery, good prices on big batteries at least that is so here in France. It's possible to get a 900CCA battery in.
 
second that. Had all sorts of probs with a replacement from Quick ****. I purchased a diesel spec one from the main stealer. Wow mega huge chunk and not let me down in 3 years and still oik if the kids leave there lights on overnight. It wasnt more expensive than one from a motor factors
 
Hi
I have a Numax marine 110 amp, 1000 cca and it only just fits, 2mm taller, wider, longer and it wouldn't fit, was a bit of a struggle to get the cables on as they were reluctant to exit out there allocated route, Ohh and it don't seem to have much problem spinning the engine.
 
Got a Yausa 1000cca battery from allparts for about £100 all in,... perfect fit!!

Try all the motorfactors... if ytou know someone with a trade account...that always helps too!
 
owners manual states diesel 1o7 amp, i put in a 110 , alls sweet now. go top quality varta, yuasa or bosch.
 
now thats better with the replys now i have some idea of what to put in to my p38 thanks guys

any more thoughts
