With the progress of science and technology, more and more No.5 batteries are replaced by rechargeable lithium batteries. However, in many cases, No.5 batteries have strong compatibility and are easy to use. Next, let's see whether the perfect combination of lithium battery and No. 5 battery - Shuerbo USB rechargeable lithium battery can meet our daily life.

Unpacking

Minimal packaging, only one plastic box and one label paper, on which the battery parameters, instructions, precautions, etc. are marked.

Local details in different directions. There is a rubber rope between the battery body and the charging plug cover to prevent loss.

Experience 1: Outdoor strong light flashlight

The standard strong light flashlight with 5400mAh capacity of 26650 lithium batteries is equipped with a battery converter, which can be replaced by three No. 5 batteries in an emergency. Here we put the Shuerbo USB rechargeable lithium battery into the converter.

There is no need to worry about the large size of the battery due to the complex structure, which is just suitable for the converter.

Visually check that there is no difference between the brightness and the original battery.

After the flashlight was used intermittently for 1 hour and 21 minutes, its brightness quickly darkened, and it was nearly not bright within 10 seconds. However, the original 26650 battery began to darken slowly due to the power when it was used for about 1 hour. This indicates that the voltage of the Shorebo USB rechargeable lithium battery is stable during use, and there will be no voltage drop due to the reduction of power, which will lead to the failure of normal use due to the insufficient power supply of electrical appliances. It is suitable for audio, camera, 4WD, electric light and other appliances with strict power requirements.

2、 Repeater

With the development of science and technology, tape has gradually faded out of our lives, but some English textbooks (such as Foreign Language Research Edition) still use tape to provide audio and listening training for textbooks, and the repeater has survived so far. Although the repeaters are equipped with external power supply, sometimes it is inconvenient for the power supply to move back and forth. In particular, most boarding junior and senior high school dormitories do not have power sockets, so battery power supply is particularly important.

Repeater is also a big power user. Ordinary dry batteries need to be replaced frequently, which is neither economical nor environmentally friendly. Rechargeable batteries are a good choice.

The repeater plays high school English (foreign research version) on 13 and a half sides, and each side lasts about half an hour. In total, it can play for about 7 hours after one charge (intermittent play, span 3 days, and stay in standby during the period). During the play process, there is no slow down or voice change due to insufficient battery power. After the power is exhausted, the power is cut off completely, and the display goes out.

3、 Radio

Although many radios now have built-in lithium batteries, many high-end full band radios still use No. 5 batteries. The radio we tested uses two No. 5 batteries. During the use, the intermittent play exceeds 10 hours. Due to the time limit, the battery is not exhausted.

4、 Charging

The Xiaomi charger I bought a few days ago has just 4 sockets. It will charge for about 90 minutes after all the sockets are plugged in. During this period, there was no overheating. Mobile power supply can also be used for charging.

Summary:

1. The voltage is stable and will not cause damage to electrical appliances
   

2. The charging is fast. Compared with the traditional Ni MH and Ni Cr rechargeable batteries, the Shuo Erbo USB rechargeable lithium batteries charge quickly and have larger capacity

3. No need for special charger, easy to use

4. Disadvantages: Without a charger, if there is no hub device or multi port USB charger, it is impossible to fully charge 4 batteries at one time
