Things to look out for in a replacement battery.

Before you get a new replacement for your battery, these are a few things you need to consider – 

  • Size of the battery

Every vehicle has a specification for battery size, and our team will consult your vehicle manual and make sure that the battery is the right fit for your car.

  • The freshness of the battery

A code written on the battery indicates the month and year of manufacturing. The latest the battery is, the better.

  • Reserve capacity

This capacity indicates the duration for which the battery can run without recharging it again. The higher the reserve capacity, the better. This will ensure that your battery does not give up during extreme temperatures.

  • Power requirement of the battery

The power requirement of the battery is determined by the Cold Cranking Amps (CCA) and Cranking Amps (CA). CCA refers to the energy required to start the engine at a temperature of 0 degrees, and CA refers to the energy needed to start the engine at 32 degrees.

  • Maintenance of the battery

You can either opt for a low-maintenance or no-maintenance car battery based on your time commitment and investment. The best would be to do your research and find out about the pros and cons of each battery type.

  • Battery warranty

Make sure that the replacement battery comes along with a warranty certificate so that you can get in touch with the manufacturers in case something goes wrong.

  • Position and types of the terminals

Certain terminal positioning can be short, so make sure that none of the terminals touch the car’s metal body when installed.

  • Ampere hour

This refers to how much electricity the battery is capable of storing.

Battery diagnostic service.

When you need your car battery replaced, you can contact instaMek, and our team will arrive at the scene to make sure that your vehicle is up and running. But before actually proceeding with the battery replacement, they will first conduct a thorough diagnosis. You will be aware of the actual issue and can take the following steps accordingly. This is a crucial step of our battery replacement service.

Cleaning of the battery terminal.

While we spend so much moolah on ensuring that our vehicle appears in top-notch quality, why do we always ignore the inside of the car? By that, I mean that why do we not put thought and effort into making sure our battery is clean and healthy? If you have not thought about this till now, it’s time for things to change. Besides replacing and repairing car batteries, another important aspect of battery care is cleaning the battery, especially the battery terminals.

Regular cleaning of battery terminals will result in better battery performance and increase the battery’s life. You can easily clean the terminals of the battery at home, with the help of some simple materials.

Materials needed for battery terminal cleaning are baking soda, water, protective gloves, petroleum jelly, an old toothbrush and a washcloth.

Clean the battery terminals in 5 simple steps – 

  • Mix one tablespoon of baking soda in one cup of water.
  • Turn off the vehicle engine, remove the negative battery cable and then the positive battery cable. Check the battery and inspect the corrosion buildup. If you notice that the battery is swollen or is leaking, then you will have to replace the battery as soon as possible.
  • Dip an old toothbrush in the baking soda and water solution you made earlier and scrub! Scrub the terminals with the brush until all the buildup on the terminals has come off.
  • Once you feel all the buildup has been removed, rinse the battery with water. This is where your washcloth comes into play. Wet the cloth and wipe the battery clean.
  • Now, lube up the terminals with petroleum jelly, and reattach the cables. Your battery terminals are now clean!

Battery cable end replacement.

Now that your battery terminals are clean, the battery cable end should also be checked for any damage or weathering. If the ends of the cables are damaged, then no matter how much you clean or maintain the battery, you will still not get the desired performance. So if you notice that there is some visible damage, call us, and we will replace the cables as soon as possible.

Commonly Asked Questions -

Q. When to replace your Auto Battery?

  • Your car doesn’t start. A new battery has a definite capacity to provide power. This capacity is referred to as the cranking amps rating of the battery. The actual amps that a battery can supply become lower than its original rating as a battery age. Once the cranking amps fall below a critical threshold, it will be hard or impossible to start your car.
  • The battery or charging system warning light is illuminated. A mechanic must perform a few basic tests to pinpoint if a battery replacement is necessary when a battery or charging system warning light illuminates.
  • Electrical components don’t work. Vehicle electrical components such as the security system can malfunction once a battery has started to fail, and the voltage produced by the battery drops. If you are experiencing electrical malfunctions, it’s a smart idea to have the battery tested.

Q. How to change a Car Battery?

  • A temporary power source might be installed to avoid the possibility of losing radio presets or stored data in the PCM while the battery is out. When the battery is already completely unusable, this step is not needed.
  • The vehicle’s negative cable is detached from the battery, followed by the positive cable. The battery tie-down system is loosened and the old battery will be taken out.
  • Cable ends and wiring is carefully examined to ensure no corrosion and cleanliness. Corrosion can be extreme and cable replacement or wiring repair is necessary in some cases.
  • The new battery is installed and the tie-down system is reinstalled. Anti-corrosion compound is applied to the battery terminals. The positive terminal is reconnected followed by the negative terminal.
  • Some vehicles, like some models of BMW, VW, and Audi, may need PCM programming to input battery parameters. This step, achieved using a specialized scan tool, is essential to maximize battery life and avoid electrical system malfunctions.
  • The car is started and charging system output is measured and compared against the factory OEM specification to guarantee that the new battery will properly recharge. In general, charging output will be in the range of 13.8 to 14.8 volts but the exact specifications depend by the built and model.

Q. Is it safe to drive with a battery problem?

Yes, however, if you have a weak battery you might be left stranded somewhere if the battery dies completely and you cannot start your car. A faulty battery may also unnecessarily overload the alternator and could badly affect the operation of the vehicle’s electrical system, including the vehicle security system and the shift interlock.

Called to get a battery replacement Doug was our service rep and it was done quickly and efficiently. Battery replaced in no time and car was ready to go. Saved me from calling a tow truck to deliver it to my dealership. Great service and pricing was good.

I've used Instamek a couple of times before and had Doug as my mechanic this time! He came and replaced my battery for me and was super friendly and fast! 5 stars to Doug!! My only issue is that instameks pricing is quite a bit higher than others for the same services!

I really appreciated Doug from InstaMek coming and installing a new battery in our car (in -30, I might add) and getting the vehicle up and running. He came at the scheduled time and was thorough and efficient and I wouldn’t hesitate to recommend.
