- It is believed that priming becomes necessary if the voltage drops below 1V/cell. Primary alkaline and lithium batteries can be stored for up to 10 years with only moderate capacity loss. You can store a sealed lead acid battery for up to 2 years. Since all batteries gradually self-discharge over time, it is important to check the voltage and/or specific gravity, and then apply a charge when the battery falls to 70 percent state-of-charge, which reflects 2.07V/cell open circuit or 12.42V for a 12V pack.

How to Handle a Dead Car Battery The average car battery will last for about three to five years. In some cases you'll find it fails right in the middle of this scale and needs replacing at the four-year mark. The exception to this rule of thumb is the modern AGM (Absorbent Glass Mat) technology. This is found in batteries rated for 6 or 7 years.

Car Battery Life - How Long Does a Car Battery Last Under ideal conditions, one automobile battery can last up to six years, but several factors decrease this optimal lifetime. A study of 2,769 sample 12 volt batteries conducted in 2004 showed that the average lead acid battery life is 50 months. Batteries in the northern US had an average life of 56 months compared to those in the south which had an average life of 43 months. Lead acid batteries last longer in cold climates as warm climates increase water loss and sulfation. Car battery life span range is 2 to 5 years. The most simple and effective way to extend the life of an automotive battery is to keep it charged close to 100%.

- When storing your notebook for longer than 1 month, HP recommends discharging your battery to 50% and removing it from the system. Be sure to store at a reasonable room temperature (~25 C). If storing for more extended periods, it is recommended to recharge the battery to 50% every 6 months or so. If the notebook will be unused for more than 3 months, discharge the battery to approximately 70% before storing. For prolonged storage, check the battery capacity every 6 months and charge back up to 70%.
