Water in its purest form is not a good conductor of electricity. However, the story changes the moment water contains dissolved substances especially salts, in which case it instantly becomes a pretty good conductor. It is for this reason that saltwater conducts electricity very well.
Generally speaking, one must not handle any electrical equipment that has fallen into the water until such equipment has been unplugged from the supply outlet or socket. If you handle any electrical appliance that has found itself in water, electricity will pass through you into the ground and this may harm or even kill you in extreme situations.
To guard against this ugly occurrence, most electrical appliances such as car battery chargers, hairdryers, and many others, now come with grounding conductors through which electric current can be discharged into the ground without necessarily passing through you with disastrous consequences.
Having said all these, it is pertinent to ask, can I change A car battery in the rain? Yes, it’s perfectly safe to do so (on a moderate downpour) and the reason is that the 12 volts delivered by car batteries isn’t enough to electrocute you.
While there may be some splash of water on both terminals and some amount of current flowing, it is still not enough to cause a short circuit. So yeah, you can change your car battery on a medium downpour.

Does Rain Affect Car Battery?
On its own, rainwater does not affect a car battery as such, particularly when it is not connected to the electricity supply outlet. However, before you re-install such battery back into the vehicle, you must make certain that it is completely wiped off every trace of water by using a clean and dry rag to clean it.
In addition, even after wiping it clean of moisture, you may need to open dry it for absolute certainty. There is the matter of the effect of temperature on car batteries, since low temperatures, as may prevail in the rains, is likely to make batteries sluggish.
This is the reason why cars start with a lot of difficulty in the cold as against when the weather is warm or hot. In essence, rainwater makes car batteries sluggish such that they may not be able to start the car at once but rather after repeated attempts.
What Happens If A Car Battery Gets Wet?
When a car battery gets wet, the chance of electric shock increases when naked conductors connected to it are carelessly handled. For this reason, great care must be taken by wiping it free of any traces of moisture before handling, to guard against any accidents from electric shock.
Furthermore, when a car battery gets wet, there is the possibility of a slight drop in its voltage, which makes it a little more sluggish such that it may not be as effective as it should be. This battery sluggishness is due to the fall in temperature that is caused by the cooling effect of water on the battery. It is for this reason that cars start with difficulty in the cold unlike in warm weather.
Can You Charge A Battery In The Rain?
The general rule is that you must not charge your car battery in the rain, but where that has become absolutely unavoidable such as when it begins to rain after you might have started charging, then you are advised to immediately remove the battery charger cord from the supply outlet or socket.
Furthermore, you must not use the charger again until you are absolutely certain that the charger is completely dry. The problem is not as grievous as it was before now since most electrical appliances now come equipped with a grounding conductor which minimizes the risk.

Some specialists recommend the use of long cables that will effectively connect to the battery in the car outside in the rain, while maintaining the car charger and electricity outlet away from the rain, in order to prevent the charger from getting wet and any attendant problems that may result.
Despite all these procedures, it is still preferable that you do not charge/change your car battery in the rain, but where you unavoidably must, this is how to go about it. (Read Also:How To Recharge A Car Battery Unturned)
How Do I Safely Charge A Car Battery In The Rain?
Charging a car battery in the rain is not very different from charging it in other cases except that in this case, you must ensure that the grounding conductors are fully operational for your protection. After all, it is in the anticipation of these kinds of situations that modern electric gadgets are provided with these conductors.
Unless it is absolutely unavoidable, you are advised to desist from charging your car battery in the rain. In order to charge your car battery, the following steps must be executed in the sequence they are given, but as stated earlier, if you must do that in the rain, the grounding conductors must be in place throughout the procedure.
Step 1: Find Suitable Charger
Before you embark on any car battery charging whether in the rain or not, the first thing to do is to find a suitable or appropriate charger. In this step, you should first test the voltage of the battery with a multimeter or a voltmeter so that you can set the dial to read DC voltage.
Set the dial to 20 which will measure between 0-20 volts. Thereafter, connect the red cable to the positive(+) terminal and the black capable to the negative(-) terminal of your battery while the engine is turned off and preferably parked throughout the previous night so that you can get a more accurate reading.
Step 2: Check Contact Points
You should check to make certain that the contact points or the battery terminals on the upper surface of the battery are not suffering from any corrosion.
If they are, rid them of this corrosion with a piece of sandpaper, while wearing gloves as you do so, in order to avoid any contact with your skin.(Read Also:Can I Use Jumper Cables For Inverter?)
Step 3: Disconnect Battery
In this stage, you are required to disconnect the battery starting with the negative or black lead before the positive or red lead, and move them to one side. The disconnection of the battery may reset your dashboard and most other settings such as the radio. For this reason, you should have the security codes at hand so that you can reset them afterward.
Step 4: Connect Charger
This step involves connecting the charger and keeping it as far away from the battery as the cables will allow. Thereafter, you should proceed to attach the lamps of the charger to the correct terminals by connecting positive to positive and also negative to negative, before plugging in the charger to the electrical outlet from the mains.
Step 5: Turn Car Charger On
It is at this stage that you will turn on the car charger, but be sure to find out from the user manual whether the charger stops automatically or not when the battery is fully charged. If it does not, you will have to manually disconnect it once the charging is completed.
Some very classic chargers are capable of monitoring the battery condition and adjusting their charge cycle to suit the requirements of your particular type of car, in order to avoid overcharging the battery which may lead to the destruction of its cells.
Step 6: Disconnect Charger When Fully Charged
Finally, disconnect the charger and reconnect your battery, but before doing this, make sure that your engine is switched off and also remove the charger lamps.
During the reconnection of the battery, connect the positive or red lead first before the negative or black lead next. This is the reverse of the procedure used during disconnection where you have to disconnect the negative or black terminal first before the positive or red terminal.

Can You Jump Start A Car In A Thunderstorm?
The most important thing when charging your car battery is to avoid sparks while doing it and because of this, it is not recommended or safe to charge your battery in a thunderstorm.
However, if you must, you are advised to make the connections as carefully as possible in order to avoid creating sparks and also to stay as far away from the vehicle as possible through the use of long cables.
Though expert opinions on the matter vary, with many opting to avoid car battery jump starting in a thunderstorm, the few who entertained the idea actually emphasized the use of very long cables, if you have, and also maintaining a reasonable distance away from the car.

What Are Some Of The Causes Of High Engine RPM?
The acronym RPM stands for revolution per minute which is the number of times the crankshaft rotates around its axis every minute. This factor determines the fuel consumption of your vehicle and hence, if you wish to keep fuel consumption down in your vehicle, then courtesy demands that you maintain it at normal levels.
Apart from excessive fuel consumption, high RPM also leads to environmental pollution due to the emission of hazardous gases. What causes high RPM in vehicles? In the case of automatic vehicles, transmission fluids convey power from the engine to the transmission and it also lubricates the various parts of the transmission system.
However, when the transmission fluid begins to leak, your car is bound to start to rev higher than normal. This may occasion delayed or erratic gear shifts. In addition, worn or slipping clutches will cause the engine to rev higher as the transmission overworks to function properly.
Furthermore, a slipping clutch will cause your vehicle to lose power and labor to stay up to speed. A faulty sensor that determines when gears should be changed will cause an abnormal increase in the vehicle’s RPM and the engine has to work harder.
