correct way to store batteries
How to store batteries
The battery is deteriorated from the beginning, right now, VGP-BPS8, VGP-BPS8A, ,VGP-BPS8Bthey leave the factory perishable products. There are some simple precautions, the battery users can slow down the aging process. This article provides guidelines to reduce the ability of age-related loss, and how the Prime Minister and save the new battery.
For the majority of the recommendations of the battery storage temperature of 15 ℃ (59 ℉). While the lead-acid batteries must always remain fully charged, nickel and lithium-based chemicals should be stored at a 40% state of charge (SoC) of the. The level of the minimum age-related capacity loss, but maintaining a business, and even with some self-discharge the battery conditions.However, in the electrode and electrolyte electrochemical differences between manufacturers vary the voltage slightly. 50% of the chip to read about 3.8V, and 40% of 3.75V. Store lithium in an open terminal voltage of 3.75 - 3.80V ions. Rest time to allow the battery voltage reading charges 90 minutes.
Figure 1: Non-recoverable capacity loss of lithium-ion batteries and nickel-based battery post. High fee levels and high temperatures speed up the capacity loss.
One lithium-ion family, has a cobalt-manganese (spinel a slight advantage in the storage area) at high temperature. Temperature of nickel-based batteries have also been increased, but more or less than lithium-ion batteries.
Lithium-ion power, most of today’s notebook computers. Many notebook computer battery box up to 45 ℃ (113 ℉ during operation). A high level of charges, the combination of ambient temperature to enhance the adverse conditions of the battery. This shows that a number of notebook computer battery life.
Nickel-metal hydride can be stored for about three years. A reduced ability in the storage time is permanent and can not be reversed. Cool temperatures and some fees aging. Ni-Cd store is quite good. Field trial wrapped up in nickel-cadmium storage batteries started 5 years later, is still good performance cycle. Alkaline and lithium batteries (primary) can store up to 10 years. Capacity loss is minimal.
In a sealed lead-acid batteries can store up to two years. A regular class fees, also known as the ‘refresh charges, must be prevented from opening the battery voltage drop below 2.10V. (Some lead-acid batteries may allow a lower voltage level.) Is responsible for acid-induced shortage, it can suppress the negative plate charge and discharge current oxide layer. Class fees and / or riding a bike in the early part of the loss recovery capability.
Start a new battery
The manufacturer’s recommended 24-hour trickle charge of the nickel-based batteries, the new and long-term storage. This service will be equal for all cells, the level of fees and redistributionVGP-BPS9, , VGP-BPS9/B, VGP-BPS9/S , VGP-BPS9A, VGP-BPS9A/B of the electrolyte to remedy dry spots on the separation of the electrolyte caused by gravity. The best is to verify prior to use with the analyzer battery capacity. This is especially important in critical applications.
Riding a bike (start), proposes to restore the lost capacity, nickel-based batteries have been 6 months or longer preserved. A slow charge by one or several discharge / charge cycles will do so. Is subject to recovery under the condition of the battery to be stored. The longer the warm storage temperature, the more cycles will be required. Prime Minister of the Kai-tat cell analyzer program will automatically apply the required number of cycles to restore full capacity.
Nickel-based batteries are not always fully formed when the leave the factory. Application of multiple charge / discharge cycles through normal use, or with the completion of the formation of the battery analyzer. To achieve the required number of cycles at full load the difference between battery manufacturers. Cells to regulate the quality of after 5-7 cycles. Those lacking formation may need 50 or more years of the cycle, to achieve an acceptable level of competence.
What is the difference between start-up and the formation of? For the user, regardless of symptoms for their own lack of capacity. The difference may be due to the formation needs to be done in this only once when the battery is new, at the same time start to be long-term storage, each repetition.
Lithium-ion battery provides full functionality of the initial fee. Lithium-ion battery manufacturers insist on not to start is essential. However, the boot is a useful starting point, preliminary verification of battery performance. Excessive cycling should be avoided because of wear-type effect.
Li-ion battery protection circuit inside the battery is known to cause some problems after long-term storage. If the battery is discharged and left to use, self-discharge will further drain the easy battery pack and eventually drip of about 2.5 volt battery protection circuit. At this point, the charger will no longer recognize the battery and the pack appears dead. Advanced battery analyzers (Kai-tat) function to start protection circuit of the step-up program, so that charge. If the battery voltage has fallen below 1.5V/cell, and in the state maintained for a few days, a recharge should be avoided for security reasons.
In order to reduce the production of new batteries self-discharge, advanced lithium-ion pack features sleep mode, to maintain, until they are activated by a short charging protection circuit. Ex post, the battery is still operational and the advantages of sleep mode no longer applies.
Cited the use of lead-acid batteries should be fully responsible for, followed by discharge and recharge. Verify through the discharge capacity is important, especially if the battery is critical applications, such as in the medical device. Once started, also suggested that the deposit of 6 months and longer battery life. Battery analyzer services will start automatically.
It is believed that partial or full compliance with the application every 6 months or so, improve the performance of lead-acid batteries. Sufficient to avoid excessive emissions, because it will wear down the battery unnecessarily.
Although the battery capacity loss of life can not be eliminated, the simple guidelines to minimize impacts:
Stored in a cool dry storage area battery. Frozen proposal, but should be avoided. When refrigerated, the battery should be placed in a plastic bag to prevent condensation
Is not fully charged Li-ion batteries and nickel-based batteries before. So that they can apply to use pre-charged, and some fully charged. About 40% of the country store lithium-ion charge (3.75-3.80V/cell open terminal). Lead-acid batteries must be stored fully charged.
Do not store lithium-ion fully depleted. If empty, charge for about 30 minutes before the store. Since the depletion of the battery discharge may lead to the line protection circuit to prevent charging.
Do not store lithium-ion battery, the date of purchase to avoid the stock, even with a lower price. Observe the production date, if any.
Never left the nickel-based battery charger sat for more than a few days. The long-term trickle charge causes crystalline formation (memory).
Has always been stored in battery for camera a lead-acid battery is fully charged state. Observe the open terminal voltage and charging the battery every 6 months or recommended by the manufacturer.
