How to jump start a car with cables


Face it, there will be days where you forgot to turn off your headlights. If not, even for the most diligent of car owners who check their car battery routinely, car batteries might lose their charge and fail to start your car engine.


In this scenario, you can try jump-starting your car's battery with another can and simple jumpstart cables. Here's how:


1. Park both cars with their front facing each other, and then turn off the engine


2. Connect the first end of the red (positive) cable to the positive terminal of the dead battery


3. One the same red (positive cable), connect the other end to the positive terminal of the good battery on the other car


4. Next, connect the first end of the black (negative) jumper cable to the negative terminal of the good battery


5. Then, on the same black (negative) jumper cable, connect the other end to a clean, unpainted metal surface under the disabled car’s hood


6. Start the car with the good battery and let it run for at least 5 minutes before attempting to start the car with the dead battery

How to change dead battery car especially for those in Petaling Jaya


Most of us would instinctively search for how to change dead battery car if we face a dead car battery. While there are plenty of trusted repairmen out there who provide the labor to change a dead car battery service, the ability to change your dead car battery is useful in many situations.


If your car battery is in need of replacement and you've managed to secure the right battery for your car, here's a step-by-step guide on how to change a dead battery car.



Step 1: Put your car in parking, open up and stabilise the hood


Safety is a priority, so make sure the car is parked and the emergency brake are engaged.


If possible, avoid changing your car battery if it is parked on an inclining slope. This is to ensure your car stays secure when you're working on the car battery. 


Once your car is ready, open up the vehicle’s hood and allow it to cool enough that you can work on the parts of your car hood without the risk of burning yourself.



Step 2: Identify the positive and negative terminals


One of the similarities of car batteries to your regular AA batteries is that they both have positive and negative ends.


On most cars, the positive (+) terminal comes with a red plastic cover, and is connected to red wires. On the opposite end, the negative (-) terminal comes with black covers and is connected with black wires.



Step 3: Detach the cables connected to the terminals


At this point, it's important to remove the negative/black cable first. You can use something like a wrench to loosen the nut holding the cable on the negative terminal of the battery. Next, detach other cable (red/positive) from the battery.



Step 4: Remove the entire car battery


You should see several clamps holding the battery in place. Inspect them carefully and then remove them.


Once you set aside the clamps and fasteners, you should be able to remove the battery entirely. Be careful to keep your hands steady in order not to spill any chemicals from the battery.



Step 5: Clean the terminals and connector cables


You can utilize a wire brush or the rough surface of a sponge together with a battery cleaning solution to clean the battery tray and the cables. Then, proceed to dry them completely and thoroughly. Never install a car battery if there are any wet parts remaining!



Step 6: Insert the New Battery


It should be straightforward from here - just remove plastic covers on the ends of your new battery. You can then place your new car battery in the tray while aligning the positive and negative ends of the battery to the matching cable positions.


You can then reinstall the clamps - connect the positive end (red or positive cable to the red or positive terminal) and tighten with a wrench. Next, do the same with the black or negative cable and terminal.


You should also double check your connections are secure by attempting to move it around - it shouldn't be shifting and it should feel tight and secure.



Step 7: Close the hood and start the car


Your car battery should be working well! If your car still has trouble starting, it's time to contact your repairman who provides change a dead car battery services!

Malaysians love road trips; that's a fact! With COVID-19, road-tripping is going to be an even more popular way of travelling for many Malaysians! In fact, the roads are already loaded up with vehicles and people who are trying to escape the everyday grind and find an escape somewhere. However, nothing spoils your travel plans like a car breakdown when you're far from home and away from your usual mechanic or service centres! As road trips are supposed to be for fun and relaxation, but a car breakdown will turn that time for pleasure into absolute misery. But you can avoid that if you take some time beforehand to get your car ready for that long trip! Before you leave for your next road trip, here's a quick car battery checklist before long journeys to other states! We'll also cover where you can get your car battery checked for free and where's the best supplier of car battery replacements! A quick checklist before you go on a long journey: a) Check that all your car's fluids are good to go You can either send your car in to a service centre/workshop or do it yourself! Just park your car on a flat ground area and wait a few minutes after you switch the engine off. Then your readings will be correct! If you know how to do it, check the brake fluid , power steering fluid, engine oil, coolant, transmission fluid, and even windscreen wiper fluid. If any of them are low or look like they're in bad condition, top them up or change them entirely! b) Pay special attention to your engine oil Road trips involve long hours of driving at high speeds - this stresses the engine significantly if it's not performing at its optimal condition! You should perform the standard dipstick test - if it's showing heavy, black signs on the dipstick, or if it's been more than 6 months or you have driven more than 5,000 km since the last engine oil change, consider replacing your engine oil entirely (and even your oil filter) before you depart on the long road trip. For example, CHEMPIOIL Ultra XTT engine oils are fully imported oils that are of high quality for the latest generation of modern gasoline and diesel engines with and without turbocharge! They are a Swiss brand of vehicle lubricants and fluids that can promise: Optimum protection for your car's engine at all temperatures Worry-free driving for the long run Quality 100% synthetic ester technology Reasonable pricing that boasts superior quality over many other engine oils c) Keep a wary eye out for your car's timing belts and hoses Timing belts and cooling system hoses are the most notorious parts for breaking down during road trips. Your car's belts will need to be replaced if they've become loose or worn - this can be detected via screeching sounds or vibrations. If you know how to, you should also inspect your engine's cooling system hoses in the case of cracks, leaks or any other damage to avoid overheating your engine on the road! d) Check the car battery Nothing ruins a road trip vacation like a dead car battery! Hence, it's important to keep your car battery in tip-top shape before going on a long drive! Typically, a lead-acid car battery can last around 4-5 years, but it's always safer to have a quick check even if it's a new-ish car battery. You can have it checked for free at Ex Power Battery ! If your car battery is old, you should definitely get it tested and replaced, as you won't want to wake up the next day with a dead car! A few signs that tell you need a battery replacement include slow or sluggish starts and dim headlights, especially when your car is idle!
