The dangers of batteries is that one could blow up and could kill you ////batteries emit gases wich if exposed to ignition source could cause an explosion and severe burns handle carefully and keep away from sparks or open flame dtr
Lead acid batteries can have several problems according to the type of battery. Flooded lead acid batteries in starting-lighting-ignition use can have water loss and become dry. They can be deep discharged and thus lose part of their capacity. If left unused for too long sulphation can occur that will short the internal plates and kill the battery. The paste applied to the positive terminal can flake and fall off due to vibration or excess charging, resulting in decreased power. The lead plates may corrode. If overcharged, batteries can outgas and lose water. If left standing for too long without use or charging, stratification occurs.
Lead & Acids
Mainly, I heard that it is harmful for the batteries if you allow them to discharge completely.
Yes, they contain sulfuric acid.
No. They contain harmful chemicals which could poison you if you try.
You shouldn't wear jewelry next to batteries because energy from the batteries can easily transfer through your jewelry then into your body being harmful to your body.
I would consider this very likely; many batteries have toxic (poisonous) components. Even eating just metals can be quite harmful.
Car batteries have lead, which is very toxic to the environment. Take them to a hazardous waste disposal point for them to discarded properly. AAA, AA and D batteries are not harmful so they can be put together with normal garbage.
It could explode if subjected to high temperature and product poisonous materials that is harmful to live beings.
No batteries contain harful toxic material that soaks into the earth's soil and is very harmful to the soil. Instead, send them to your nearest hazadous waste plant, they have alternte methods of disposing harful material.
Solar power is one of the safest sources of power, but can still be dangerous if the electrical converters and batteries are over capacity. Also, when maintaining the solar power, you are out in the sun and excessive exposure to the sun has been known to be harmful. So in essence all you need is the proper power converters and batteries, and some sunscreen
In general, computer batteries contain toxic substances. The acid content is not the main concern, but rather the use of elements such as mercury, lead and cadmium that cause worry.
Lithium batteries use some type of lithium in their construction and are different from more traditional alkaline batteries. One of the key features of lithium batteries is the increase in the amount of electricity that is produced from a certain size of battery when compared to alkaline batteries. This feature also has a drawback, however, since a lithium battery can have a very harmful reaction when short circuited inside of a device. This can actually cause the battery to discharge electricity and heat very quickly, potentially igniting the battery itself.
Nickel Cadmium batteries contain Cadmium, a toxic heavy metal, which is harmful to the environment. Nickel-Metal Hydride batteries offer a higher capacity(runtime)per same size(voltage output) than NiCd batteries and mcVolt Litium Ion laptop batteries have a higher capacity than NiMh(those sold by most manufacturers). NiMh batteries are also lighter and have little memory effect compared to their NiCd counterparts. mcVolt Li-ion laptop batteries are light, have a higher capacity and have no memory effect compared to NiMh and NiCd batteries.
