Knowing Your Interstate Marine Battery Warranty

On the brighter side of things—Interstate marine batteries (among others) are one of the most affordable and high-performing cells you can find. On the darker side of things—those Interstate marine batteries at your local Costco may not be in your best interests. Arrays can get “old” and thus, you may wish to read up on this piece to know whether your Interstate marine battery warranty is right on the dot.

Do Interstate Batteries Have (Or Provide) A Warranty For Their Performance Products?

Indeed, the batteries at Interstate do possess a warranty clause so that your satisfaction is in priority—there is more to the situation, though.

To put in some little bit of context, and among the Interstate brand, there are categories of batteries that are rather popular among consumers:

1. Interstate “marine” batteries with a division in between starter batteries, deep-cycle batteries and dual-purpose batteries, often in use for all kind of boat applications.
2. Interstate “M” batteries which are usually in widespread use for their function and performance with regards to RV or Rental Van applications.

For either category, the warranty period usually falls in between 12-months or 6 months.

But, specifically, one should be wary of a battery, especially when you take into consideration a specific factor:

The Battery Manufacturing “Age”

This context is more of an issue and more of a problem from the outsourcing outlets of a brand to another site (say a Costco) and thus, it is quite essential to know how long a “battery shelf life” to estimate if a battery is “old.”
The kind of battery above is overdue for a much, much shorter battery lifespan than in the previous estimation.

How Long Should Performance In An Interstate Battery “Last” In An Outlet

Fortunately, getting to know the battery manufacturing estimation of your battery is not that hard:

1. Remember to find the “code” for the date of manufacturing at the top of the cell.
2. Remember to find an alpha-numeral code (which can be 4 or 5 digits long) and will usually be in a battery casing in the corner part of the battery.
3. Remember to go and find a (+) label of the positive terminal of your battery—this is just in case the corner part of the battery does not give you the “code.”
4. Remember to make a note of the information so you do not forget—the first code digit will be usually be manufacturing “month” with a “letter” as a form of indication with March as C and a month like June as F.
5. Remember that the second code digit will be in numbers and the numbers indicate a year—with 5 reporting 2005 and with a 0 indicating 2010 (these repeat with cycle runs of around ten years).
6. Remember that if the “stars align,” an F5 will be the equivalent manufacturing re-charge date of June of 2005.

Are Interstate Batteries Relatively “Maintenance-Free”?

The batteries at Interstate are, indeed, maintenance free—this is in so far true in that they make a point to let the customer do relatively little for the battery to stay safe.

In particular, and to maximize—for example—an Interstate marine battery warranty lifespan (of around 12-months), the company makes it a point to create high-quality structural casing as well as performance parameters in balance (to avoid overheating, sulfating and over-charging).
