Features To Consider When Buying Batteries For 6.7 Cummins
Finding the right battery is not as simple as choosing the most powerful battery that fits the budget. There are several other features you must consider. Knowing that, buying batteries can seem complicated.
Here are five features you must consider to buy the right battery for the 6.7 Cummins:
#1 Battery Size
When it comes to buying the correct battery for your 6.7 Cummins, one should be well aware of the dimensions of the battery. It’s because not every battery is the same. And even if they look the same, they differ in dimensions.
It’s better to be pre-prepared than being confused while finding your batteries. You can take your owner or user manual along with you to the shop. If somehow you lost your user manual, it’s better to consult the battery owners. They can provide you with guides from which you can refer and find the one for your car.
Note: You have to be precise about the size of the battery because an oversized one won’t fit the battery tray, and the under-sized one will wear out before than expected.
#2 Price Of The Battery
An essential thing to note while buying a battery for your Cummins engine is to be on a budget.
Today most lead-acid batteries are available for under $200, while the price of deep cycle batteries is above $250
#3 Battery Age
Have you ever thought about why your lead-acid batteries fall short of service so quickly? Well, here’s why!
Years ago, lead-acid batteries didn’t come in robust packaging but rather in a naked form. They were vacuum sealed that could be removed. Further, the owner could fill the acid or water at his convenience, and everything worked well. Moreover, these batteries lasted very long.
But today, the case is different. Manufacturers fill the batteries with acid for the chemical reaction to take place. It results in the deterioration of the metal rods/plates inside the battery due to the response.
It implies that the minute these chemical batteries are set up, the reaction starts taking place at a prolonged rate, reducing the battery’s shelf life.
Today, this is the case in almost every battery that is available in the market. Therefore, it is advised not to buy a battery that is older than three months from its manufacturing date.
Moreover, if your car batteries are imported, ensure that they are fresh and not more than 1 or 2 months older than their manufacturing date.
#4 Reserve Capacity
The standing capacity of the battery is shortly referred to as RC or Reserve Capacity. In other words, the reserve capacity is the amount of power your new battery has by default.
If the new battery has a high reserve capacity, then your car can run on the battery itself even if the alternator trips off. Don’t randomly choose a battery solely based on its reserved power.
Refer to the owner manual and tally the range mentioned in the table. Odyssey Batteries comes with highest reserve capacity among the ones discussed above.
#5 Location And Category Of The Terminals
The next thing is to check that your battery fits the system. For that, you have to look for a new battery that has the exact dimensions as your previous one.
Don’t forget to check the terminal positions; there is a positive and a negative terminal on every battery. But, they should be in the right place as per the fit. The terminals can be on the top or side-mounted.
It is also possible that they are in their proper place as per the requirement but flipped in positions.
If the latter happens, the cables won’t reach the terminals properly as cables cannot intervene. Stretching and straining the wires can damage the entire system. Thus you will end up paying a heavy bill.
Therefore, to ensure that you are getting a suitable battery for your diesel engine, check the BCI number.
Starting your diesel engine in chilled winters may seem like breaking the ice with your head. But worry not, this guide highlights one of the top-performing batteries that provide a high CCA value to start your engine even in the nail-biting winters.
