Hey guys,

So my brother jumped in his '94 camry this morning and went to start the engine, only to cause a massive bang and steam to come from the engine bay. The battery had exploded, blowing one of its sides mostly off.

Any ideas what could have caused this?

Cheers

he just had the alternator replaced, does that give any help? sorry to ask, but im just interested in knowing, if the bonnet was open and/or someone was nearby they could have got a good splash of acid. also, want to avoid this ever happening to my car lol

Just last month, the same thing happened...

I'd hate to imagine what could happen if your cranium was under the bonnet and you asked someone to start the donk > :)

OR...

would it be any less tragic for it to happen to my battery next to the petrol tank. > RIP

Happens more often than you'd think, mostly on machinery that has a rough ride. Trucks, earthmovers, tractors etc.

The connections from the posts to each cell deteriorates and eventually you get a weak link just waiting for you to hit the starter.

Big amps and a spark in an atmosphere with hydrogen makes short work of the battery case.

Lucky it was just a single battery.

Bigger machines have 24V with 4X6V batteries side by side, so when 1-blows it usually takes all the others with it.

Lots of acid..........................................

here you go , the battery can crack down the side from being held by the bracket allowing gas to escape through the top seal , explosion caused by the gas mixed with air and the inrush current through the battery internally when starting . see it happen from now and then

Need to be a member to see that link terry..

Apologies - just noticed the deja vu so soon after an '06 Forester battery went Kabooom

I wonder "grigor" if this is what can happen with boats too? = a combo of evaporated fuel + deteriorated connections to the cells (especially in salty air)?

    • Sounds like you've got an interesting adventure ahead here with local support if you have trouble! My guess is that, unboosted, you will be OK with a small upgrade like -9. What will happen is that once the stock ECU sees more airflow than it expects it will add a heap of fuel and pull a heap of timing to be safe because it can't understand how it could get that much air without there being an issue. You will see clouds of black smoke and it won't pull hard through the midrange and top end. So, overall it will be a bit frustrating but should be OK. If you are still nervous set the base timing back 2o through the CAS, but it will be even more sluggish everywhere. As said above through...this is not my guarantee your engine won't be blown into a million pieces, leaving you looking for very hard to find parts A better idea is get a computer with logging ASAP, wire in a wide band O2 sensor and a use remote tuner. I've done multiple cars this way and while it is not as good as a specific tune on a dyno they can get it 90% right. I'd suggest if you can afford an R33 GTR these days you can afford an ECU and tune. And if you can't afford that you sure won't be able to afford the rebuild if it goes bad in the meantime,.  
    • Yeah it would be nice if someone took the time to put that sort of information together, but there are a lot of variations in looms. I think you are making this way hard for yourself if you just want to get it running....sourcing an SR20 with the right wiring will be a billion times easier than matching the RB loom to an S15 chassis. If you do end up going this way, you just need to trace every wire in the loom with a multimeter, 95% of them will go to a location you can confirm at the ECU.....and then post it up for the next person who needs it  
    • Just top it up with water, and keep a general idea of how much you added. It is normal for water to be pushed into and pulled out of the reservoir through the cap, and it should not be more than half full or it will be likely to overflow when hot. Any decent mechanic can do a pressure test of the cooling system to confirm if you have a leak. Keep in mind if it is only leaking a little and when hot it may well evaporate before you see it hit the ground
    • I'd ask the shop what they used and use that. Mixing coolants is sometimes OK, sometimes not, and you have know the details of each coolant to know whether it's a good idea or not.
    • Is it alright to top up with just another green coolant?
