W3526602 Posted April 18, 2010 Share Posted April 18, 2010 Hi, I have had a battery explode ..... big bang. Somebody suggested that I had reverse charged it. Thats possible as it had only just come off the charger .... but you can only fit the charger clips the wrong way round if the battery is absolutely flat. And a neighbour had a battery explode, for no apparent reason. A flat battery can freeze, and split the case. I've had that too. 602 Link to comment Share on other sites More sharing options...
hallii Posted April 18, 2010 Share Posted April 18, 2010 I had a battery explode on a rescue boat (private sailing club), it blew the fibre glass panels apart and deafened me for a couple of minutes. Luckily it was a semi inflatable so it didn't sink! Hallii Link to comment Share on other sites More sharing options...

spospe Posted April 18, 2010 Share Posted April 18, 2010 Batteries can explode due to the hydrogen given off during charging and discharging igniting. Usually the bang is not too loud, more of a "PHFFFFAAAAAAAAT" kind of sound. Link to comment Share on other sites More sharing options...
PJay Posted April 18, 2010 Author Share Posted April 18, 2010 colin It was Ok on last check about 3 or 4 weeks ago We had an accident back in september, so it may have got cracked then, and we did not spot it, as was still working then Link to comment Share on other sites More sharing options...
PJay Posted April 18, 2010 Author Share Posted April 18, 2010 Spospe we dont need to charge batterey, as we nearly always use hook up when in the van As we were not in van, (haven't used it yet this year) not sure when it happened, so don't know what sort of noise it made. We will be taking it to Adventure Motorhomes on tuesday, so it will have a really long run, should sort out any mor problems prior to our trip to Spain/Portugal next month. P Glad we are not the only ones to have this happen, never heard of it before. Just shows you're not too old to learn something new P Link to comment Share on other sites More sharing options...
Brambles Posted April 18, 2010 Share Posted April 18, 2010 If it is just a crack in the battery then may well just be the plates swelling from sulphation and not actually exploded. Did any acid leak out? Batteries do not normally expode when just sitting and no sparks around. They can explode if stored at very high temperatures and an internal short developed causing even more heat and then they can thermally run away. If the accident was caused quite a shunt, it is possible it caused a plate short, a short from lead falling of plates or fractured and internal connection which may have caused a spark when next charging or discharging. Or as already mentioned if discharged it could have frozen. Link to comment Share on other sites More sharing options...
