Car Batteries Buying Guide & FAQ
Now that I have gone through the reviews of the best car battery, let’s delve into the buyer’s guide.
As I have mentioned in the beginning that car batteries come in different models and other parameters such as cold cranking amps, size and amp hours. That said, you need to be vigilant when making purchases to avoid wrong purchases.
What features to look for when buying car batteries?
Size of the battery
It’s important to ascertain that you’ve chosen the right size of your battery. Normally, batteries fall under different groups which signify the right size.
The best way to clear the confusion of wrong battery sizes is to consult your owner’s manual. It will come in handy as the battery size is always specified. Alternatively, you may directly measure the size of your old battery or look for size prints on it.
Cold cranking amps
If you are driving in cold climates often, consider the battery with high cold cranking amps. The cold cranking amps (CCA) indicates your battery’s power to start the engine in cold weather so the higher the better. It is important to have this high number because in winter cars struggle to start instantly.
However, do not confuse the cold cranking amps with the cranking amps rated at 32 degrees Fahrenheit which is equivalent to 0 degrees Celsius. But this number is not as significant as the cold cranking amps in showing the power of the battery to start the engine at extremely cold temperatures.
Regardless of whether it is used or just sitting on the shelves, the battery is continually losing its discharging/losing its value. For this reason, I reckon you look for a fresh battery.
Oftentimes, batteries have the manufacture date printed on. The date is shown as two characters which may be, for example, B0 where B refers to February and 0 refers to 2010. Ideally, you should only opt for batteries that are a few months old. More strictly, I would choose a 1 month old.
Maintenance or Maintenance free battery
The other battle o decision making is whether to buy the sealed or unsealed battery. If you are like me and hate maintenance, I would opt for the maintenance-free battery despite being expensive.
The traditional lead-acid batteries require maintenance on a regular basis. You have to replenish water and the acid. Oftentimes, there could be a leakage on the battery. However, they tend to be inexpensive but heavy too. To avoid the maintenance stress, opt for the sealed batteries.
In my review I have included only the sealed AGM batteries. AGM refers to Absorbent Glass Mat, which is a modern technology that differs from the flooded lead acid batteries with the way the electrolyte solution is controlled.
In AGM batteries, the electrolyte solution is held in the glass mats hence absorbent glass mat. Lead acid batteries, on the other hand, have the electrolyte freely flooding the plates hence the leakage possibilities when it malfunctions. The surface area in AGM batteries is increased by thin glass fibers woven into a mat to hold the electrolyte solution for a long time.
Lead acid and AGM batteries both contain acids. AGM electrolyte solution is composed of sulfuric acid. The best characteristic feature of AGM batteries is that they can withstand low temperatures and they self-discharge slowly which gives them longevity compared to lead acid batteries. Also, they charge faster than lead-acid batteries.
Without doubt, I would opt for an AGM battery anytime in spite of an expensive price tag. It’s a lifetime investment and your car will not experience problems due to non-maintenance.
Battery reserve capacity
Battery’s reserve capacity is also an important consideration when making your purchases. If your alternator fails or if you are charging electronic components while the car is off, a reserve capacity can still charge for a limited time.
It is measured in minutes and denotes a fully charged battery at 80 degrees Fahrenheit that will discharge 25 amps until it depletes below 10.5 volts.
It’s important to consider how the manufacturer takes you, the consumer, serious with their products. Usually, there is the warranty and prorated period which entails a partial reimbursement.
If the warranty is represented as 36/84, it means that 36 months warranty and 84 months prorated period. This differs from manufacturer to manufacturer.
How to take care of your battery?
Taking care of your battery is also important. Although AGM batteries are referred to as maintenance free, you still have to take a good care of them.
There could be a build-up which leads to terminal’s corrosion. Watch this YouTube video as a guideline on how to generally take care of your battery.
Batteries dos and don’ts
When using batteries, regardless of which type, you need to exercise extra caution on them. Safety first! Safety first! Safety first!
Conduct regular inspection to monitor how the battery performs especially in hot weather conditions. After using the battery, recharge it.
Do not add new acid solution to your battery and do not use incompatible, high-output chargers when charging your batteries. Also, avoid adding tap water into your batteries (flooded batteries) as tap water could contain minerals that can corrode your battery. When the engine is running, do not disconnect the battery cables.
I have reached the end of my buyer’s guide and the reviews. I believe that this information will help you choose the best battery for your car. Batteries are important and, surprisingly, many car owners only consider replacing their batteries after experiencing a shutdown of power. It’s important to continually monitor your battery performance. If you are incapable of doing that, seek the services of the mechanic nearby.
I have reviewed AGM batteries, which have become standard in modern batteries. If you are still using the old lead-acid batteries, it is high-time you consider upgrading unless you enjoy the maintenance part. AGM batteries are, however, expensive, but worth the price of money. They are corrosion resistant and spill-proof thanks to the advanced technology of the absorbent glass mat that holds the electrolyte solution.
