If you want to buy AAA smart chargers and rechargeable batteries, are there good quality and low pri

The domestic Pinsheng is good, it is recommended to charge quickly and easily, full of self-stopping, and fast charging.

500mA for 2 AAs, 1000mA for 2AAs, 500mA for 4AAs

Pinsheng's battery quality is also very good, the consistency is very good, the actual capacity is sufficient, and the discharge current is large.

Fast and easy to charge is about 35 yuan, and the No. 7 800mAh battery of Pinsheng is about 13 yuan a card.

It is recommended to supply Sheng's and Sanyo's, these two brands have the highest credit-to-price ratio. And the specifications are complete.

The rechargeable battery should be written as "rechargeable battery", and the rechargeable battery will generally indicate the capacity of the battery, such as 1600mAh, 2000mAh, and there will be a sign of the rechargeable battery type, such as Ni-MH (nickel-metal hydride), Ni-Cd (nickel-cadmium), there are currently five categories on the market: nickel-cadmium, nickel-metal hydride, lithium-ion, lead-storage, and iron-lithium.

As it says, warning:battery may explode or leak if recharged or disposed of in fireWarning:

If the battery is charged or thrown into a fire, the battery may ** or leak, this is not a rechargeable battery.

AAA is what we usually call a No. 7 battery, and the general size is: diameter 11mm, height 44mm

AAA is 7 and AA is 5.

Usually rechargeable batteries will have a capacity mark, will indicate the battery type, and the length of charging time, etc. Ordinary batteries such as carbon batteries and alkaline batteries are not rechargeable!

It's definitely not a rechargeable battery, AAA is a No. 7 battery.

The general carbon battery is characterized by the lowest price, and the retail should be below the yuan, and the international label of the 5 battery is R6 or R6C. This kind of battery has a short shelf life (within 1 year), and is generally only used on low-grade toys, which is easy to leak, so it is recommended that users try not to buy it.

No, and AAA is not necessarily a carbon battery.

According to the charger parameters, the charging current of the AA battery is definitely AA, and the charging time is roughly calculated to be hours according to the battery capacity and charging efficiency.

In addition, the battery is marked with a charging current of 250mA and needs to be charged for 16 hours. - Therefore, it can also be inferred that the charging time required is 16 * 250 175 = 23 hours.

For a 2700mAh high-capacity battery, it is not recommended to charge with a charger with such a small current.

Don't buy a No. 7 battery charger alone, it's best to have a charger that can be charged at both No. 5 and No. 7, it just has a larger active range of the electrodes, so that batteries No. 5 and No. 7 of different lengths can be charged inside.

Some batteries can't be recharged, and they can be dangerous! Use with caution!

Is it a number seven rechargeable battery? This kind of charger generally has a special charger.

AAA, the battery is very powerful and easier to use.

Domestic Pinsheng, Pinwei is very good within 50.

Pinsheng Xiaolingchong is less than 20.

First, the reference is different.

1. AA battery: No. 5 battery (i.e. AA, R6) is one of the types of batteries, 2. AAA battery: is a dry battery standard in the United States, and the No. 7 battery in Chinese mainland or the No. 4 battery standard in Taiwan Province of China is compatible with it.

Second, the size is different.

1. AA battery: its size is 14mm in diameter and 50mm in height.

2. AAA battery: The battery is cylindrical, with a height of millimeters and a diameter of millimeters.

Third, the use is different.

1. AA battery: with its economy and excellent environmental performance, it will replace alkaline batteries and nickel-cadmium batteries.

AA Battery:

No. 5 battery (AA) is one of the battery types, and its general size is 14mm in diameter and 49mm in height. (Rechargeable AA battery: A battery that can be reused multiple times).

AAA Battery:

No. 7 battery, the cell is cylindrical, millimeters high and millimeters in diameter. It is a common battery and is smaller than AA batteries.

Differences: The size is different, the No. 5 battery is larger than the No. 7 battery, charging AA is a rechargeable battery, which can be used repeatedly and repeatedly, and the AAA battery is an ordinary battery that cannot be used many times.

The difference between AA battery and AAA battery is that the size is different, AA is the No. 5 battery, AAA is the No. 7 battery, the general digital camera uses the AA5 battery, and the AAA7 battery is used in the *** medium, if the battery is abundant, try to buy the battery with a large nominal capacity, and it is best to buy the same brand of supporting charger as the battery, so that the efficiency of the battery can be maximized.

AA is a No. 5 battery, AAA is a No. 7 battery, and the size is different.

For rechargeable batteries, the real metric is how many milliamps are the capacity of the battery.

The former is a No. 5 battery and the latter is a No. 7 battery.

If you choose a battery, the larger the capacity of the same model, the better.

1. If the battery is marked rechargeable, it means that it is a rechargeable battery.

2. Look at the voltage, the voltage of the rechargeable battery is, and the voltage of the disposable battery is. Secondly, see if there is a capacity number on the label, if there is a label asking for capacity, it is a rechargeable battery.

3. Charge with a direct charger to see if the phone shows the charging status; If you use the universal charge, see if the indicator light is on, and if it is on, it means that it can be charged.

4. Use special instruments for testing.

5. Non-rechargeable alkaline batteries are allowed to carry the LR symbol, and the commonly used AA or AAA rechargeable batteries are mostly nickel-metal hydride rechargeable batteries, all with NI MH logo.

Non-rechargeable alkaline batteries with the word LR;

The most commonly used AA or AAA rechargeable batteries are nickel-metal hydride rechargeable batteries. Both have the words ni mh.

Without the words LR and NI MH, it is a cheaper cardboard battery, of course, it is not rechargeable.

The most intuitive measurement with a universal meter, if the voltage exceeds the above, it is a non-rechargeable battery, and if the voltage does not exceed it, but it can still light up the small bulb, it is a rechargeable battery.

A rechargeable battery cylinder should have a circular groove near the end of one end, while a non-rechargeable battery is a completely smooth cylinder.

The domestic ones will have rechargeable batteries written on them, or marked with the words NiMH and Nichrome, and the rechargeable batteries are particularly heavy. The most obvious is the ??? marked on the top ha h or ??? milliamps, there will also be a small icon with a power plug inside the battery on the top of the inlet.

rechargeable

There is this in the sense of rechargeable.

No, you cannot. The nominal voltage of the No. 7 rechargeable battery is, and the universal charger is to charge the mobile phone battery, the voltage of the current mobile phone battery is almost all, if the No. 7 rechargeable battery is charged, there will be a false situation that the No. 7 battery is not fully charged, and the No. 7 battery will be charged, so it is impossible to charge the No. 7 battery.

This is mainly to see if the voltage is appropriate, you see if the charging voltage required on the battery is within the voltage range of the universal charger, if so, you can charge.

However, in order to ensure battery life and safety, it is best to use a dedicated charger.

It doesn't make sense to look at the nominal capacity, the nominal capacity can be fake, you want 30000, add 2 zeros after 300 and you're good to go. The No. 7 battery is 900 mAh at most, but the cycle life of 900 mAh is a little less than that of 850 mAh, so it is better to buy one with an actual capacity of 850 mAh.

It is recommended that you go to **buy a Tianyuan battery with a Tianyuan charger, a good battery does not have a good charger, it is useless, just like an 850 mAh battery, charged with 20% power, only 170 mAh, it is better to buy a 170 mAh charge directly. Nowadays, the outside charger is generally charged 20%-30%, not more than 50%.

GP and the next generation have the problem of false capacity, you can buy Tianyuan batteries and then buy them to use in the same appliances to compare the battery life, or find a single-cell torch to discharge and test the capacity. And their cycle life is not more than 100 times, about 20-30 times, and the next era is a little shorter than GP. A dozen times, but the next era is cheap, and it's true.

Hello: The best brands of civilian rechargeable batteries are GP, the next generation, and the top ones in China. AAA battery is currently the most stable NiMH rechargeable battery, which can do 900mAh to 950mAhIf the capacity is elevated, there is a suspicion of false standard capacity.

In addition, you have a misunderstanding, the larger the capacity of the rechargeable battery, the better, depending on where you use it, the performance of the self-discharge and cycle times of the battery with high capacity is not as good as the medium and low capacity.

The best brands of civilian rechargeable batteries are GP and the next generation, which are among the top in China.
