A dry battery one without an electrolyte will maintain on the shelf indefinitely. Once the electrolyte is placed in the cells, the process begins. With usage and age, however, the flooded lead acid builds up sludge in the sediment trap, which causes a soft short when this semi-conductive substance reaches the plates.
This can cause issues when the battery gets old. I assume it happens at a slower rate while on the shelf, but will still happen over time as it becomes aged.
What this means is, a battery with acid in the cells can only sit on the shelf for so long before it must be recycled or it will not work right. Have no fear, though, lead from batteries is one of the most recycled things we humans pull out of the ground. A battery which has sat on the shelf for too long, while it may not provide you good usage, will still be able to be exchanged for a new one under the normal battery warranty programs.
I'm sure batteries are sold beyond their expiration dates, but they are also easily replaced. The warranty date code is located on the top label of the battery. The first character is either a P or S.
The next two digits determine the month, the third digit is year and the fourth digit indicates the manufacturing plant. For example, P N means the battery was made in September See the answer below for more information about battery life. Either way, the warranty period for your battery starts from the time of purchase. It pays to get a Solar brand battery tester which uses a conductance test to evaluate how many CCA is left in your battery.
Made with Absorbed Glass Mat AGM technology — this no maintenance battery was engineered with safety and longevity in mind. These long-lasting batteries have an impact- and break-resistant plastic case for durability and a terminal design that resists acid leaks and seepage corrosion.
This durable design protects against the worst enemy of a truck battery — road vibration — and is optimized to be corrosion-resistant. Designed to minimize acid leaks, seepage, corrosion, and black post to help keep the terminal posts of your battery clean and corrosion-free.
Certainty Starts Here: with aftermarket parts that follow the same step quality approval process as GM Original Equipment. Due to manufacturing defects, some batteries will end up not charging, no longer holding a charge, or not working as intended. ACDelco batteries are one of the most popular batteries on the market and are well-known for their reliability, ruggedness, and longevity. ACDelco backs their batteries with to month warranties , well within the average lifespan of most batteries.
If you are having problems with your ACDelco batteries, have it checked at their service and retails centers. There may be a material or workmanship defect on your battery that warrants replacement. Battery date codes are used by manufacturers to indicate what when and where the batteries were manufactured.
It also allows you to determine the age of your battery and whether it is still covered by the warranty. A typical car battery lasts between two to five years. If your battery is old, it may no longer hold a charge like it used to and needs a replacement. Also, it may no longer be covered by a warranty since the coverage period was way past. When buying a replacement battery, a newly manufactured one, needless to say, is better than old stock.
Before purchasing a new battery, however, it is important to determine whether your old battery is still covered by the warranty to avoid unnecessary expenses. The battery date code on ACDelco batteries is in the alphanumeric consisting of letters and numerals format.
The date is preceded by either a P or S, the next two numbers indicate the month and the third number indicates the year. I understand that AC Delco encodes the month of manufacturing a car battery using two digits and encodes the year by one digit. I'm puzzled by this ambiguity regarding the decade of manufacture.
Just as importantly, how can a manufacturer of AC Delco's renown make the date this ambiguous? Is it, for instance, the case that a battery that has been sitting on a shelf for 11 years will be so unusable that it could not possibly be sold as a one year old battery? NOTE: Much of your question seems to be a rant, so I will answer the last part, which seems to have gone unanswered to this point. This means if a battery sits on the shelf too long, it will need recharged after a period of time to be fully operable in a vehicle.
That is for a battery which is stored wet with acid in the cells. A dry battery one without an electrolyte will maintain on the shelf indefinitely.
