As it heats up, the acid in the battery gives off gases and pressure builds inside the case. some venting can occur releasing the gas (which is explosive). Any ignition source can cause the battery to explode.

What causes a caravan battery to boil?
If there is a cell damaged the voltage will not rise sufficiently and the charger will keep on charging and will eventually boil the battery dry. You should however check the voltage of the charger by disconnecting it from the battery and using a digital volt meter voltage should be no more than 14.5 volts.
What happens if you overcharge a leisure battery?
Overcharging causes excess heat that can cause the plates within the cells to buckle and shred their active material. The battery will also react to the overcharge by producing excess hydrogen and oxygen as the water within the electrolyte breaks down.
How do you prevent battery explosions?
However, there are a few things you can do to prevent such an incident from ever occurring with your device.

How much charge should a leisure battery have?
As a general rule, the charging current should not exceed 0.2C, where ‘C’ is the amp-hour capacity of the battery. Once charged, it’s important to drop the voltage back to about 13.6 volts to avoid damage.
How often should you charge a leisure battery?

Some types are more resistant than others to this phenomenon but, as a rule of thumb, batteries in storage and not in circuit should be charged every three months or so. A lead acid battery will not perform well if it is completely discharged.
What should a 12 volt leisure battery read when fully charged?
The reading should be between 1.1 (discharged) and 1.28 (fully charged). To determine how long the battery can go between charges, check the capacity, which is normally measured in amp hours (Ah).
What to do if a battery explodes?
If the battery explodes — which is rare, but possible — you could get this chemical on your skin or clothes or in your eyes. The remedy is to flush with plenty of water. After removing most of the chemical with water, neutralize what remains with vinegar or lemon juice.
Can batteries explode when not in use?
Luckily, major explosions caused by Li-ion batteries are an uncommon occurrence. If they are exposed to the wrong conditions, however, there is a slight chance of them catching fire or exploding.
Can a maintenance free battery explode?
‘maintenance free’ automotive type batteries that cannot be periodically topped up with water in conjunction with constant float charging can produce explosions with the associated potential of injury to anyone present and the risk of fire.
How long do leisure batteries last?
The performance of leisure batteries decreases over time, meaning that they probably won’t last longer than five years. To give it the best chance of lasting for as long as possible, it’s important to: Apply a thin layer of grease or Vaseline to the battery’s terminals.
Does a caravan leisure battery charge when driving?
If everything is wired correctly, yes, your car will charge your caravan battery whilst driving. When you start the engine of your car, if the caravan is plugged in, the current of the car (alternator + battery) will recharge your caravan battery.
Why does my caravan smell like rotten eggs?
A common cause of why your RV smells like rotten eggs is that anaerobic bacteria in your RV water heater tank reacts with the sulfur and magnesium of the anode rod. This interaction produces hydrogen sulfide gas – your rotten egg odor.
How do I know if my leisure battery needs replacing?
If you have an old battery, consider getting it replaced if it’s been in use for more than a few years, as most batteries will no longer be effective after approximately five years. However, the lifespan of a battery depends on many factors, including how many appliances it’s having to power.
Why does my leisure battery keep going flat?
The main causes of battery drain is a faulty leisure battery. The battery may be old, cold or just need to be replaced. A faulty piece of equipment such as the charger or anything connected to the leisure battery could cause a drain.
How does a leisure battery charge in a campervan?
Most motorhomes offer two methods for charging the leisure battery: via the on-board mains charger when on hook-up and from the engine-driven alternator when on the road.
Does electric hook up charge leisure battery?
If you use mains hook-up, the leisure battery will be being charged by the on-board charger, and in most caravans and motorhomes this is not a very sophisticated system. It can actually damage the battery, this time by over-charging it, causing gassing and drying out of the battery.
Can I charge my leisure battery with a car charger?
There is nothing wrong with using a car battery charger to charge a battery that is described as a leisure battery. The important point is that it should not be left charging a battery for long periods of time…….so it is not a charger for people that want to fit and forget. You do need a smart charger for that.
Are Aldi Battery Chargers any good?
Aldi Car Battery Charger – waste of time and money.
I have just bought this and I have had similar problems to others. The Mode button doesn’t change the function as specified in the user guide so it looks like it thinks the battery is a 6V battery not a 12V battery. Probably only good to trickle charge.
How long will a leisure battery last without charge?
A 110 amp hour battery may give 110 hours at 1 amp but at 11 amps it wont give you 10 hours it will probably be nearer 8.5 hours,this would be to fully discharge the battery. It is recommended that deep cycle batteries are never discharged to less than 50% so in effect it will only last app 4 1/4 hours.
