Hi All, Just thought I would share some info. After having a dead battery replace by the RAC last night I discussed the idea of relocating the battery to the rear of the Zed for better weight distribution. The chap from the RAC said that they have noticed a very high rate of sealed batteries being used in older cars for racing going flat within 12 months, this has happened to a friend of mine also. the RAC have had people looking into this and it appears as though the charging cycle of these new batteries is not suited to older vehicles hence they go flat within a year. This info is purely for information, please make up your own mind.
sure if your alternator is 30 years old !! the battery can go flat. R33 GTST, and r32/33 GTRS all have there battery in the boot from factory.. if your cables arnt fat enough tho when relocating you can run into issues (huge voltage drop) and can lead 2 poor charging
the MF, sealed battery installed in black bess prior to my purchase lasted me more than 4 years .. and it was an el cheapo "super charge" brand ... go figure .... ... and my blue zed, purchased last December had a RACQ, MF sealed battery fitted .... seems your man could be spouting a bit of home grown bollocks ...
The guy is talking out his arse to a degree.... There has been a move over a couple of years now to lead/calcium based batteries as they are better suited to high current needs of newer vehicles. They are designed to give alot of current in one hit, and then recharge very quickly. For daily driving this is ideal. Older batteries were made with lead/antimony plates which break down quickly when used with "modern" electrical systems due to the high current. The trade off here is the calcium battery will go flat sooner (if not used) because that is the way it is designed to operate. If you have a race car that is rarely used then you are better off using a deep cycle battery, although this will take a prolonged period to recharge to 12.6v compared to a regular lead/calcium battery. This has absoloutely nothing to do with sealed/unsealed, it's more about choosing a battery that suits your requirements.
Well guys as usual the members on here are all professional experts so I will bow to there experties as I'm sure they all work for formula 1 teams or work in laboratories, i shall refrain from passing on any information in future.
Also just wondering who would have a 30 year old battery in a 18 year old car hmm. Gosh that would be silly.
:W: What answer did you want? Just confirmation that your RAC man was right? So you could listen to so-called 'experts' or people that have actually put one in their Zed
sealed...good! well on the sealed vs not front i can definately say that my next battery will be the sealed variety! It was the servicable (non-sealed) battery that sealed the fate of my zed as the spilt battery acid destroyed the passenger turbo wastegate vacum line causing over boosting and thus a destroyed piston! :mad2:
... little do you know what you say ... Rob 260 IS a professional/expert and does work in the battery field ...!!!!!! .. a check of his posts will reveal a long history of providing good advice to members on battery care and battery issues in general .... so ignore his advice at your own peril ... !!! ..as for my post, it was based solely on personal experience with two zeds over at least a 4 year period .... take it or leave it ...!!!!!
MY parents WRX goes flat if you dont drive it for a week or so. It gets little use these days. Apart from when i drive the slow POS to get parts for my car. 150awkw just doesnt do it for me sorry. LOL.
? Dude no need to pack up your toys and go home... You were half right in what you posted, and now you have some more info at your disposal. Everyone wins yeah?
They have a pretty pissweak small battery to begin with. You could fit something with a higher RC (reserve current) if you change the terminals and get an aftermarket bracket (7 1/2", cheap as). Or get yourself a ctek xs800 battery charger from Repco or similar. Should be less than $100 and good for lead/calcium batteries due to high charging amps (.8). You can leave it hooked up indefinately and it will stop your battery going flat in the first place.
