Battery is leaking from the top

The battery in my 34 is leaking from the top where you put water in it from. Yesterday I had to take the horn fuse out from the engine bay and this caused the battery light to turn on and my turbo timer was showing 15.3v . At the time I didn't know it was the horn fuse but I drove my car like that for half an hour to get home then when I searched google I found out it was cause of the horn fuse. When I checked the battery today I saw that the tray had lots of water and a lot had leaked onto the railing and caused white deposits. I took it out and wiped it down. Car still has power to everything and battery doesn't seem weak but you u think I f**ked the battery by driving it for half an hour on 15.3v?l?

The battery should be able to handle that voltage. The question id be asking is, why is the battery leaking? Overfilled, or is it fubarred? I recently had one leak from where the top plate is joined to the body. Took it back as it was still under warranty and swapped it.

I made sure the water I put in the cells were about 2 inches from the top and made sure the caps are sealed. Had to use a screwdriver and hammer to loosen and tighten them because they were a weird design (two sideways triangles) and it ate into it a bit but don't think it's that. The water also came out black for some reason. The century battery didn't get hot after driving it on 15.3v and the battery hasnt swollen up or anything. But there were white deposits on the railing by the battery so that is almost guaranteed battery acid

alternator is overcharging and causing the acid to bubble up and leak out of the battery. check the voltage at the battery terminals while engine is running, anything 14.7 and above is a problem

its all good now i think its like 14.7 or slightly lower after i put the horn fuse back in and battery light turned off. Just wondering if the battery or alternator would go anyday now since i overloaded the battery and drove on 15.3 for half an hour.

Also whos bright idea was it at nissan to cause this battery overload problem by simply taking the horn fuse out?

id say the battery would be fine, maybe shorted life somewhat but hard to say. if fairly new it will cope better, just make sure fluid level is sweet and keep an eye on the voltmeter

i got non xenon headlights now but i got stock xenon wiring on my car. So since they dont match up i had to do a temporary wiring so the lights turn on from the spotlight cable lol i got no fuses in for the headlights and it still turns on. Could that be short circuiting it?

also the battery is still slightly leaking from where the 6 cells are. i made sure they wernt overfilled and tightened the caps. WHAT GIVES? its a year old century battery

it wont short it if its wired up properly, i mean its already a closed circuit. but its a great fire hazard if it fails.

get it replaced under warranty while you can.

      Ceramic turbine damage to engine - what did yours do?

      By Erelyes · Posted

      Ha, well, it's been.... a bit of a journey. Things have taken much longer than I'd hoped. I'll probably put up a thread at some stage. Hopefully soon. The car's not done any kms since my update in June though, put it that way.

      Here's the chart for fuel pressure vs. current draw, assuming your base fuel pressure is 3 bar and you run like 0.5bar boost on WOT, you should only momentarily hit 9amps here and there. (Ignore my prev post, I cannot read a chart these days it seems)

      Those comp test results are not hideous. Whether they are accurate or not (ie, when that comp tester says 140 psi, is the real pressure120, 140 or 160?) is unknown to us. The state of the battery used to crank it over is unknown, etc etc. Many people around here would say that the absolute values and the spread are perfectly fine to just add boost and keep going. I personally would be happier with a narrower spread than that, but even the diff between 125 and 145 is not terrible. That one cylinder at 125 though, has probably copped some damage relative to the others. You should inspect the valves seeing as you've got it open. Do you know how to measure installed ring gaps? That, and an inspection of the rings themselves, is how you will determine whether they need to be replaced. If you're not good to do these things, take the block and the pistons and rings to a shop that is, and ask them for the go/no-go on them. Do the bores need a hone at all? If so, you might well be justified in getting some different pistons in order to get away from the ring supply problem. Whether you're happy to spend a lot more money right now, on more gear, rather than less money, but an amount that looks stupid given that you will only get a handful of rings in exchange for that money, is for you to decide.

      Ok so i would love some advice here please, i purchased an R33 a few months back and its had a few mods done to the engine, its an RB25det running a Master ECU, 1200cc injectors, bigger turbo, oil cooler, oil filter relocation kit, Spool H-beam rods, acl/ross pistons. When i removed the motor from the vehicle (as its getting a respray) i thought i would compression test it and these are the following results. Cylinder 1-145psi, Cylinder 2-143psi, Cylinder 3-125psi, Cylinder 4-145psi, Cylinder 5-140psi, Cylinder 6-135psi this test was done with the motor on the ground and powering up the starter motor. I dropped the sump and found broken oil squirters on cylinder 3,5 and 6. I was told my rings are probably worn so i stripped the motor completely to get a new set of rings for it. The trouble is no one has these rings anywhere and they have to be custom made by Ross over in the states and will cost about $600+$200 delivery. My question is how can i tell if my rings are at fault and if they are still ok and is this price ok for a set of rings?
