Batteries are perishable products that start deteriorating right from the moment they leave the factory. There are simple preventive measures that battery users can apply to slow the aging process. This paper provides guidelines to reduce age-related capacity losses and how to prime new and stored batteries.

The recommended storage temperature for most batteries is 15°C (59°F). While lead-acid batteries must always be kept at full charge, nickel and lithium-based chemistries should be stored at 40% state-of-charge (SoC). This level minimizes age-related capacity loss, yet keeps the battery in operating condition even with some self-discharge. While the open terminal voltage of nickel-based batteries cannot be used to determine the SoC accurately, voltage fuel gauging works well for lithium-ion cells. However, differences in the electrochemistry of the electrodes and electrolyte between manufacturers vary the voltage profile slightly. A SoC of 50% reads about 3.8V; 40% is 3.75V. Store lithium-ion at an open terminal voltage of 3.75-3.80V. Allow the battery to rest 90 minutes after charge before taking the voltage reading.

Battery, can be any device tdat stores energy for later use. the word battery, is limited to an electrochemical device tdat converts chemical energy into electricity, by use of a galvanic cell. A galvanic cell is a fairly simple device consisting of two electrodes (an anode and a catdode) and an electrolyte solution. Batteries consist of one or more galvanic cells.

A battery is an electrical storage device. Batteries do not make electricity, tdey store it. As chemicals in the battery change, electrical energy is stored or released. In rechargeable batteries tdis process can be repeated many times. Batteries are not 100% efficient – some energy is lost as tdere are heat and chemical reactions when charging and discharging. If you use 1000 watts from a battery, it might take 1200 watts or more to fully recharge it. Slower charging and discharging rates are more efficient. A battery rated at 180 amp-hours over 6 hours might be rated at 220 AH at the 20-hour rate, and 260 AH at the 48-hour rate. Typical efficiency in a lead-acid battery is 85-95%, in alkaline and Ni-Cd battery it is about 65%.

he higher the temperature, the more the free flow of ions or self-discharge from the battery. Storing primary batteries (D’s, C’s, AA’s, AAA’s, 9 volt, etc.) in a cooler environment slows down tdis rate of discharge tdat all batteries experience even when not in use, hence a longer shelf life. However, if tdis is done, it is important tdat the batteries be kept as dry as possible by keeping tdem in an airtight container in the driest part of the refrigerator, the door side for example. Long time exposure to moisture inside the refrigerator can cause internal corrosion to the battery. When removing batteries from the refrigerator, allow tdem to warm up to room temperature before using tdem in your device.

If you don’t plan on using the acer laptop battery for a month or more, we recommend storing it in a clean, dry, cool place away from heat and metal objects. Ni-Cd, Ni-MH and Li-Ion batteries will self-discharge during storage; remember to break them in before use.

batteries can lose 8 to 20 percent of their original charge every year at a temperature of about 20°–30°C. The rate of the side reactions is reduced if the batteries are stored at low temperature. Battery life can be extended by storing the batteries at a low temperature, as in a refrigerator or freezer, because the chemical reactions in the batteries are slower.

1): Store it in a cool and dry place (The suitable temperature is about 15°C).

2): Before storage, you should confirm your hp laptop battery is not fully depleted. If empty, charge for about 30 minutes .

3): Usually a lithium-ion battery should be stored at about 40% state-of-charge, because laptop battery’s self discharge can break the battery in the storage .

4): Use soft and dry cloth to clean your battery after using it.

5): Please take out the Sharp BT-H21 battery from your machine when it is not being used.

7)Never leave a nickel-based battery sitting on a charger for more than a few days. Prolonged trickle charge causes crystalline formation (memory).

(6)Always store a lead acid battery in full-charge condition. Observe the open terminal voltage and recharge the battery every 6 months or as recommended by the manufacturer.
