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

Figure 1 illustrates the repayment capacity of the storage temperatures and different levels load of more than a year.

Figure 1: No loss of repayment capacity lithium-ion and nickel batteries after storage. The high load levels and high temperatures accelerate the loss of capacity.

Among the lithium-ion family, the Cobalt has a slight advantage over the spinel Manganese () in terms of storage at high temperatures. nickel-based batteries are also affected by high temperature, but to a lesser degree, that lithium-ion batteries.

Lithium ion most laptops today. The battery compartment on many laptops rises to about 45 ° C (113 ° F) during operation. The combination of high charge level and elevated ambient temperature presents an unfavorable condition for the battery. This explains the short lifespan of many laptop batteries.

Nickel-metal hydride batteries can store about three years. The decline in capacity that occurs during storage is permanent and can not be reversed. Cold temperatures and a partial charge slows aging. Nickel-cadmium stores reasonably well. Test reveled that field NiCd batteries stored for five years and are still performed after priming cycles. Alkaline and lithium batteries (primary) can stored for up to 10 years. The capacity loss is minimal.

The sealed lead-acid battery can store up to two years. A load of topping newspapers, also known as "discount rate" is necessary to prevent the open cell voltage from dropping below 2.10V. (Some batteries lead-acid may allow lower voltage levels.) insufficient load induces sulfation, a layer of oxidation on the negative plate that inhibits the current flow in loading and unloading. Topping loading and / or bicycle can restore some of the lost capacity in the early stages.

Priming new batteries

Manufacturers recommend a charge of nickel-based battery for 24 hours when new and prolonged storage. This service offers all the load cells at equality and redistributes the electrolyte to remedy dry spots on the separation caused by the gravitation of the electrolyte. You should check with a capacity battery analyzer before use. This is especially important in critical applications.

Cycling (priming) is recommended to recover lost capacity after a nickel-based battery is stored for 6 months or more. A slow loading, unloading followed by one or several charging cycles will do this. The rate of recovery is governed by the conditions under which the battery was stored. The longer and hotter than the temperature of storage, more cycles will be necessary. The first program of the Cadex battery analyzers automatically applies the number of cycles required to recover full capacity.

Nickel-based batteries are not always fully formed when leaving the factory. Applying several charge / discharge cycles through normal use or with a full battery analyzer training. The number of cycles required to reach full capacity varies among manufacturers of the cell. Cells perform the following quality specifications 5-7 cycles. Those who lack training may need 50 or more cycles to reach acceptable capacity levels.

What is the difference between the primer and training? For the user, both symptoms manifest as lack of capacity. This difference can be explained that the training needs is performed only once when the battery is new, although priming should be repeated after each prolonged storage.

Lithium-ion batteries deliver full power after the initial charge. The manufacturers of lithium ion cells, insist that no priming required. However, priming is beneficial as an initial contribution and to check the battery performance. Cycling should be avoided due to excessive wear effect.

The internal protection circuit of lithium-based batteries is known to cause some problems after prolonged storage. If the battery is left discharged after use, the self-discharge will further drain the pack and eventually drip the protection circuit of about 2.5 volts per cell. At this point, the charger no longer recognizes the battery and the pack appears dead. Analyzers Advanced Battery (Cadex), the feature of Boost program triggered the protection circuit to enable a recharge. If the cell voltage has fallen 1.5V/cell below and has remained in that state for several days, a recharge should be avoided for safety reasons.

To reduce self-discharge batteries new manufacture advanced lithium-ion battery packs have a sleep mode that keeps the protection circuit until activated by a short position. Once engaged, the battery remains operational and the advantage of sleep mode does not apply.

Lead acid batteries should be prepared by applying a full charge, followed a discharge and recharge. Checking through capacity management is important, especially if the battery is dedicated to critical applications like feed for medical devices. Priming is also recommended after storing a battery of six months and more. Battery analyzers provide the Priming service automatically.

It is believed that a partial or total discharge, is applied once every six months or so enhances the performance of lead-acid batteries. Avoid too many full discharges because this would erode the battery unnecessarily.

Although the loss of capacity over a battery life can not be eliminated, simple guidelines to minimize the effect of:

* Keep batteries in a cool, dry storage. Refrigeration is recommended, but freezers should be avoided. When refrigerated, the battery must be placed in a plastic bag to protect against condensation.

* No charge for lithium and nickel batteries before storage. Keep them partially charged and apply a full charge before use. Store lithium-ion at about 40% state-of-charge (3.75-3.80V/cell terminal open). Lead acid batteries should be stored fully charged.

* Do not store lithium-ion fully depleted. If empty, before.storage load for 30 minutes. Auto-discharge of a dead battery can cause the protection circuit trip, preventing a recharge.

* No store lithium-ion batteries and avoid buying dated stock, even if offered at a reduced price. Observe the manufacturing date, if available.

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

* Always keep a lead acid battery in full load condition. Observe the open terminal voltage and recharge the battery every 6 months or as recommended by the manufacturer.

EN Denaq a good battery for a Dell laptop?

my Inspiron 1420 battery needs to be replaced and I found one on ebay I want to buy. IT is a Denaq battery, my question is, is a good battery? and I get a message in windows that I have to replace a battery from Dell and buy only from them, is this true? help.

You do not have to buy a Dell battery in your Dell laptop. That said, the laptop will behave more happy if the battery replacement is a Dell - and you have a larger share of mind, because you do not know how good it is Denaq. spend the extra money - It is worth it.
