If your charging a dc battery and reverse the leads what will happen to the battery A- trickle charge B- drain or discharge C- explode?

Both B and C. DC is polarity specific, by reversing polarity with a charger you are causing current to flow backwards through the battery (internal) this could cause the electrolyte to heat up giving off a gas that expands and could eventually cause the battery to explode or just crack and leak. Most electrolytes in batteries are corrosive.

Is it possible to accidentally reverse the polarity of a 12 volt battery?
Yes it is possible, the most common way is the battery is very very drained, then you hook up the charger - to + and + to - . then it will take a while but it will do it. I do not recommend you try it as it can wake up half way thru reverse charging and explode.
How to charge a dc battery with ac output?
The best way to charge a battery from an AC source is to use a high-quality commercial battery charger that is of the correct voltage and charging profile for your battery. By "charging profile," I mean a charger that is matched to the battery's chemistry and amp-hour capacity. WARNING: Not every type of battery is rechargeable, and even rechargeable batteries can do nasty things if they are not charged properly. If you are not sure you have the right charger, please ask someone for help. If you want to make your own charger, the answer to "how" depends upon the AC source, the kind of battery, and how "good" a charger you want to make. At a minimum, you need some kind of rectification of your AC power. Your battery will tend to discharge during the part of the cycle where it is not reverse-biased, so you will need something like a diode to make sure the battery can't drain itself back into the charging circuit. Cheap chargers for car batteries, for example, are sometimes nothing more than a transformer (to convert the mains voltage down to something suitable for the battery) and a rectifier (two or four diodes). More sophisticated charger circuits are used to maximize battery life (heat from recharging can damage batteries, so charging circuits use various strategies to control the heat) and to provide the appropriate charging profile for the battery chemistry. You'll see a pretty dramatic shortening of the life of your batteries if you don't use a specialized circuit to charge some kinds of batteries. For this reason, you may want to use a commercial charger. If you really want to build a charger, try to get a kit or build from a known-good circuit.
What can cause nonstart and all electronics to not function on a 1994 Chevy Suburban?
Bad ground, Bad Battery. Or The battery was connected improperly. I.E Reverse Polarity.
What causes a battery to reverse polarity?
Discharging it to 0V (ie. absolutely empty). And not battery, but "cell" (even a small AA or AAA battery is consider a "cell" - think Duracell).Batteries are usually made up of individual cells (like car batteries, RC batteries etc.), and even if not all of them are discharged completely, if even just one cell reverses polarity, it will do irreversible damage to the battery.
Can reverse osmosis water be used in batteries?
In a pinch, you can use tap water in a lead-acid battery. Since the minerals dissolved in the water will eventually poison the battery it isn't advisable to make a habit of it. If your reverse osmosis device removes most of the minerals you can probably substitute it for distilled water but you should confirm the quality of the water it produces before making a habit of it. A quick method to check the quality would be to check the water's conductivity. Using an Ohm meter, compare its conductivity to that of distilled water at the same temperature. If the measurements are close then have at it.
If you connect a battery for charging in reverse connection will it get charged or not how about the efficiency of the battery?
If you reverse the connection of the battery charger you will discharge the battery. You may be able to correct the connection and charge it properly, or the battery may be ruined.
If the battery is not connect right to the post can that cause it to explode?
If you reverse the battery cables, yes the battery can possibly explode.

Why could a 12 volt car battery explode or burst?
Normally connecting the cables in reverse order can cause it to explode. Overcharging can also cause the battery to rupture but it is highly unlikely it would explode.
What would cause a battery on a forklift to explode?
Overcharging by the alternator or if it is connected in reverse polarity.
Will a car battery charger ruin my battery if I accidentally reverse the cables while charging?
Yes it will damage your battery if you reverse the cables. There is an article on Wikipedia about it at this link http://en.wikipedia.org/wiki/Rechargeable_battery.
How does a car battery polarity change into reverse polarity?
Car battery polarity can only reverse if the battery is completely dead and then charged with the neg. and pos. leads of the charger are reversed. This is very dangerous as hydrogen gas which is given of buy a dead battery may explode and cause personal inguiry.Likewise if the car's battery cables are accidently reversed while the battery is dead. Regards - S.S.
Where can I get the best car battery charger possible?
The Deltran Supersmart Battery Tender is the optimal choice in battery chargers for cars. It switches from a full charging mode to a float charging mode to ensure that battery is kept at maximum, it has a reverse polarity protection to ensure the user cannot be harmed, and it comes backed by a 10-year-warranty. You can buy it on amazon.com for approx. $43.
How could a car battery explode?
Auto batteries contain Sulfuric acid and all batteries produce a very small amount of hydrogen gas which is highly volatile. If the battery is overcharged it will produce more hydrogen gas than the vents on the battery can safely release. Any spark can then cause an explosion. Also connecting a jumper cable in reverse can cause the battery to explode.
Type of battery reverse polarisation during charging?
The positive electrode in a lead acid battery is lead plate coated with lead dioxide. The negative electrode is a special porous lead sheet or plate, both separated by an insulating permeable barrier. The electrolyte is sulphuric acid. Charging is the process of reversing the process that happened during discharge or use of the battery. At the negative terminal the lead sulphate converts to lead. At the positive terminal lead changes to lead oxide. Hydrogen ions, water and sulphate radicals combine to form sulphuric acid. In the next stage during charging the current electrolyzes water in the electrolyte, producing hydrogen and oxygen in a process known as gassing at which stage, charging current should reduce to a trickle or stop.
If you reverse polarity on the battery and the fuses are fine and the alternator check out ok why would an 81 Toyota pick-up wont stay on whithout having your foot on the gas pedal?
When the truck is idling at low RPM, the charge supplied by alternator is not sufficient to run truck and charge battery of reverse polarity. Alternator expends majority of amperage toward charging (which never takes) and increase in RPM is required to spin alternator fast enough to accomodate ignition system and charging system in unison.
