the writers workbench: rechargeable power

With the development of mobile technology, the demand for running the technology is also expanding.
This could mean using a lot of batteries, which could mean replacing a lot of money.
As a result, many people use charging batteries as an option.
Maybe the biggest problem with charging batteries over the years is that they don\'t keep charging for a long time after sitting there, so when you need to put in a new battery, it\'s a bit of a lag, waiting to charge things back to speed.
A new type of rechargeable battery was developed a few years ago.
Discharge battery (LSD)
Also known as \"pre-
Charge.
They can advance
Charge and then pack as they charge well.
LSDs will charge 85% per year and 70% for five years, although all of them are stored in perfect conditions.
The point is that you can charge them at any time and put them aside so they are ready when you need them.
In addition, they can be charged 1,000 times.
Alas, I haven\'t had a year (or five years)
Look at this.
The most famous and popular battery in this field is Eneloop, developed by Sanyo, through many other batteries, including the well-known white top Dulak, AC Delco (
Offering a range of mAH-both high and low-
Rated, the latter is best for slow charging instead of fast charging)
And the Powerex that sells its own brand Imedion.
This makes a particularly highend, long-
Non-Life brand
Rechargeable lithium battery
Including its recently improved Ultimate Lithium line
Also extended to the charging field through a series of Chargers (
More information about them below)
And the charging battery itself.
As long as you know, despite what they said on the website, a company spokesman said that the power recharge line was upgraded last fall and is now ahead of schedule
Like their competitors, charge a 80% fee a year later.

HR CHARGERAmid in the above battery is a brand that may not be familiar with, Powerex.
I noticed them because Powerex also made a brand charger.
After all, if you\'re going to have rechargeable batteries, you have to charge them at some point. The Powerex MH-C801D (
This name is also called Maha)
It\'s an impressive device and in this area you may think things should be very basic.
Most notably, it comes with eight slots for charging eight NiMH (
Nickel Metal (hydrogen)or NiCad (Nickel Cadmium)
AA or AAA batteries are independent of each other.
This is not a trivial matter: Most chargers can only charge one battery size at a time.
Also, they usually require at least two batteries to be charged before the device starts.
The latter is a special problem because the weaker batteries affect the charging of the other battery because they share one circuit. (
Also, you may only have one battery to charge. )
Powerex can charge one battery at a time, or it can charge different sizes, different startup times and mixed brands at the same time.
This is because each slot has its own circuit. (
Note: When charging multiple batteries, the company says to insert them from left to right with no empty slots in the middle.
The right side of the charger is hotter than the left. )
The car is a \"smart\" charger.
When the battery is plugged in, the battery automatically gets high power, and when the battery is fully charged, the device is lowered to trickle charge.
It stops when charging.
The device can be charged quickly or soft, but it can also charge the battery in depth. (
There will be more later. )
In general, fast charging takes an hour and soft charging is completed within two hours.
Of course, time is flexible depending on the situation.
Be aware that a quick charge may reduce the life of the battery because it runs hotter and the heat reduces the life of the battery, although degradation should be minimal, possibly 10%.
This loss is offset by the time saved by faster charging.
Soft charging works at cooler temperatures.
Given that the soft charging process of the unit is very fast, it seems to be the best way to do it unless you are particularly rushed.
By default, the device starts charging at the highest level, instead of asking you to press the \"quick charge\" option like many fast chargers.
When the inserted battery is detected, it quickly checks how much power is in the battery and starts charging.
If you want to charge more slowly and softer, you can press the button labeled \"soft\" within five seconds after the battery is charged.
Given that soft charges may be better unless there is a rush, although this is not a big problem, it is better to adopt the default mode.
No matter what mode you are in
Fast or soft charging
For all batteries currently plugged in, the device will be charged in that mode. (
Note: The AA battery charges quickly at 80 mAh on 2000, and AAA charges quickly at 700 mAh.
Therefore, you should only use fast charging mode for batteries that can handle this high current.
Of course, if the rated capacity of the AA battery is 2000 mAh or higher, the rated capacity of the AAA battery is 700 mAh or higher, this will be the case.
Otherwise, if the rated power of the battery is low, a slower soft charge should always be used.
Battery packs always give a rating. )
The above depth adjustment function is usually used for batteries that have been placed for a long time and may lose their charging capacity.
This is also a problem with the old nickel and cadmium (NiCd)
You may still have the battery instead of the nickel metal hydrogen salt today (NiMH)ones.
The adjustment will restore the battery to its best condition. (
If the shape of the battery is good enough, it can still be fully charged, which can take 14 hours, although the process will take less time if the battery can no longer be fully charged. )
To make a condition adjustment to the problem battery, you can also press the condition adjustment button within the first five seconds of inserting the battery.
While NiMH batteries are not required, it is still a good idea to have them fixed once in a while.
This may provide them with more years of service.
There is an LCD display on the 8001d that provides more information about the status of each battery than the typical green/red \"charge\" light.
When it shows a bar, it means your battery has 0-
50% of the cost, the two bars shown are 50-
80%, 3 charges are 80-
Complete 100%.
When the word \"done\" is displayed, the battery is fully charged.
Also, the empty battery icon without the bar means that your battery must be adjusted first. (
As mentioned, this is usually a very old battery that has been sitting around all the time. )
The flashing stick indicates a battery failure.
The LCD is very convenient and although there is no backlight, it is sometimes difficult to read the icon or text.
There are a few other nice features.
The most important of these may be its comprehensive safety protection.
This can prevent non-
Rechargeable alkaline battery inserted (
This is a very good thing because it is possible for them to explode if charged. . . )
And prevent you from mistakenly putting the battery back in the case of polarity reversal, which prevents the device from accepting charging.
In addition, the function prevents short circuit.
Under microprocessor control, a very small voltage difference can be detected in the range of 0 by the qq1d.
001 V, allows accurate charging of the battery.
This is the reason to charge the battery to its maximum capacity without charging too much or under charging.
Its power cord is also a universal AC power adapter worldwide, so it can use foreign current without the need for a transformer.
Although the company itself produces cheap power cord adapters (around $7).
Result, MH-
If you choose to take it with you on your trip, the qq1d will charge the battery anywhere in the world.
Two issues: you have to unplug the device when not using it because there is no on/off switch.
The wire for the power block is also a bit short (around 16\")
, Which makes it a bit inconvenient to run the charger on a table with a power block on the floor.
The Powerex MH-
The 8001d is more expensive than the basic unit you can usually find.
While $65 can be found online, it retails at $100 at the time of writing this report.
However, many of its features may be good if you\'re not just charging the battery for a rare charge --
It is worth it in the long run.
As mentioned earlier, ENERGIZER has a range of chargers in addition to rechargeable batteries.
The universal model can charge batteries of all sizes (
AA, AAA, C, D and 9 v).
Depending on the size, there are four brackets, each allowing one or two batteries. (
For example, it can charge up to 8 AA. )
Each battery has its own charging light tested separately.
You can also charge batteries of different sizes at the same time, which is a very good thing.
A good protection feature is that it does not charge until the lid is closed.
The LCD screen displays the charging status in each charging bracket.
Universal is a \"smart\" charger so it can detect when the battery is full and automatically stop charging.
It will not charge if the battery is bad.
Although the charger does not charge the battery as described above, this is not a real problem with the NiMH Battery today.
The charger usually does quite a good job of keeping the battery charged differently, although it seems a bit inconsistent.
However, it is important that the documentation shows that the charger is optimized for the Energizer brand battery and looks very temperamental on different brands, so if you tend to use non-
This may be a problem.
Time will vary, but it usually charges quickly in about three hours and takes seven hours on a soft battery, so it\'s not the fastest charger you\'ll find.
This is not a real problem for most people.
First of all, fast charging will be hotter and will shorten the life of the battery, so in any case, people may prefer to charge slowly like overnight.
Since the charging device is well maintained today, you may have a spare if there is an emergency.
Like the generic charger mentioned above, it doesn\'t adjust the battery, but it shouldn\'t be a problem for most people.
The charger works with the AC transformer and also with the universal voltage, so you can use it as a world charger (
Of course, you need to install the adapter plug. )
On the positive side, Energizer has good charging performance with some good \"smart\" features that can be used for world travel, very portable and cheap.
The best is to commit people-Battery only (
There may be problems with other brands)
A little slow.
At the time of writing this report, the strength is generally visible for $ months. 88.
ENERGIZER power charge RAPIDThe recharge does a lot of things quickly, universal, but focused and fast charging.
It can take up to 4 AA or AAA batteries at a time, and it can also charge \"widow --
One or three batteries.
It also does not allow you to insert batteries with wrong polarity.
As a smart charger, it uses trickle charging so you don\'t overcharge.
In addition, the slots work independently, which means (as noted)
You can charge odd batteries at the same time.
If there is a problem with the battery, the \"bad battery\" detector will inform you, although it looks a bit sensitive and finds that some of the batteries that are charged elsewhere are blocked.
According to its name, the charging speed is quite fast.
Although the time is different, it takes basically 15 minutes to charge two batteries and 30 minutes to charge three or four batteries.
However, they recommend placing the battery for another 10 minutes after charging because the battery will get hot. (
Similarly, as mentioned earlier, the fast charger is more disruptive to the life cycle of the battery. )
There is a built-inin cooling fan.
While there is a light that will inform you of the charging status, it is just a light.
So, if the light flashes to indicate that the battery is broken, you have to take one out at a time to check.
Also, like all Energizer chargers, it is optimized for Energizer Rechargeable batteries and is not always as good as other brands.
Also be aware that it won\'t affect the battery, though as you may have discovered now, this is not really a problem with NiMH batteries today.
It is equipped with an AC adapter as well as a convenient car adapter plug.
In addition, it has a universal voltage and can therefore be used abroad (
Even though you need the adapter plug. )
One of the benefits of fast charging is that the speed is very fast and there are several useful \"smart features that can be charged
The numbered battery is very portable and can be used for world travel at a cheap price.
The negative side is that it is limited to AA and AAA batteries, there is no soft charge and does not work for non-batteries
Battery charge.
When writing, you can find it for $29. 71.
With four AA batteries.
Smart charging is a basic charger that adds some useful features.
For example, it has an LCD indicator that shows the charging status, and a countdown timer that shows the rest of the time.
The bad battery alert detects that the battery does not charge when installed, and then turns off the charger.
There is a built-in
So it doesn\'t need an AC adapter.
It accepts AA or AAA batteries and charges two to four times at a time.
Unfortunately, it can only be charged in pairs.
In addition, the countdown timer is not particularly effective, and the company says it may take half an hour to read accurately.
For four slots, the battery charge meter will show up to four bars, which is fine, but there is only one meter per slot-
Therefore, if there are two batteries in one slot, the meter will control the two batteries.
It also seems to default to lower-
This means that another battery may be overcharged.
These devices charge the battery in about 7 hours.
It does use universal voltage, so it can travel around the world.
Smart charging devices are cheap and easy to carry and can be used for travel around the world.
