#battery test

Anyways, let's go on the results of my pics taken to see some device's battery display was. However I excluded some other items like my stylus pens from Blackweb or my two headphones set; even I would be save it for next time, but nah....

The first one is my Samsung Tab E back in March 15th, 2020; but not after wanted to charge the power bank full to 100% first. Anyway, I used the originally Samsung USB cable with it and the results was not bad so far as 33% battery left.

Back in March 18th, I usually going for another Samsung Tab E's charging again, but this time letting my tablet's battery drain out completely to 0%. Next, I'll be using a Kikkerland USB cable plug as alternative and luckily it works the same thing from my orignally Samsung USB plug. With my old iPad Mini 2 also, I can set up a timer to see how long it would charge to beginning and at the end. Once it's done, the result was little disappointing for some reason. It takes about 25% battery left and thought it would've take more than that. At least knowing from the timer can take 1 hour and 14 mintues for charging.

(Still wondering for the USB cable thing that could be an error or something. =/ )

For the second one back in March 22nd, it's my old iPad Mini 2 that I barely use it for long time; since I got my Samsung Tab E years ago and such. Kinda shamed cause when I do use an iPad for occasion, sometime the battery's precentage will go down quickly....or just saying that originally it will live for 10 hours/5-11 hours can take. Anyways, I tested on my iPad's charging; again by letting an iPad power down by 0%. Of course, I had to used the orginally iPad USB cable plug this time and It too luckily works as well. However for reason, I had trouble of battery charging progress cause of using my iPad while charging offers little bit of help. So I happen to try this again with my tablet turn off while charging. The results was 45% battery left of 2 hours and 29 minutes than 33% for my Samsung tablet. (First Try)

Shamed that I can't use my iPad while charging, So bummer....T_T

(A timer result pic in the middle is from my Samsung Tab E, by the way.)

Finally as you know, I tested on my Nintendo Switch (Back in March 29th),  but had to turn down the battery's power by 0% again for the third time. Surprise that it was charge the same from my old iPad Mini 2, but the time was 1 hour and 48 minutes in 45% battery charge. Whatever it was, not bad result still.

Now that's settles, I had some thoughts for my Kikkerland's power bank, it's capacity of 3600 mAh, and the charging: it's was a little bit mixed. the fact sometimes I had to let it charge for a moment; even I would use my devices while charging from my power bank whether on the ride or someplace, it can only charge for one/two hours and minutes. Though nothing as a big deal, however it "kinda" does....

🐰🖌Maxwell: Guessing it was a cheap one, huh? So sorry it had to come with this.

🐰👊💥May: Even thought the results looks okay, one hour and minutes for almost medium battery charge was something little bit off. Guess it only works for most smartphones, but almost not for tablets or gaming handhelds.

The mobile phone lithium battery is a finished battery composed of battery cell and battery protection board. The mobile phone lithium battery will be activated before leaving the factory. After a series of processes of filling the battery case with electrolyte-sealing-forming-dividing, the activation of the mobile phone lithium battery is completed.

The activated mobile phone lithium battery also needs to be functionally tested. The purpose of the test is to verify whether the battery quality is qualified and to prevent the circulation of inferior batteries from the source. The mobile phone lithium battery test mainly uses power, switches, electronic loads, multimeters, and other instruments to test the battery’s over-current and over-voltage, and checks whether the battery protection board can react quickly to protect the battery.In this process, we also need to use the battery test module – high current shrapnel microneedle module, which is mainly used for conducting current and transmitting signals.

Mobile phone lithium battery testing is mainly carried out for functions such as functionality, safety, and reliability, because lithium batteries are prone to heat, expansion and even explosion due to overcharge, over-discharge, short circuit, and other reasons, so they must be tested to confirm whether it can be applied.

The purpose of a mobile phone lithium battery functional test

To test whether the function of the battery can be achieved. The test content: high and low temperature charge and discharge, charge retention capacity, battery rate, capacity, life cycle, etc.

The purpose of a mobile phone lithium battery safety test

To test whether the battery protection board can cut off the current loop in time when the battery has abnormal conditions to avoid the occurrence of dangerous accidents. Test content: overcharge, over-discharge, abnormal charge, forced discharge, external short circuit, power limit detection, etc.

The purpose of a mobile lithium battery reliability test

To test whether the battery can work normally in different external environments. Test content: low pressure, vibration, impact, crush, free drop, impact, temperature change, shell stress, etc.

The mobile phone lithium battery test must ensure the stability of the current flow. As a battery test module, the high current spring micro pin module has good current transmission ability and can carry out current transmission in the range of 1-50a, and the over-current is stable and smooth, with no current attenuation. In the small pitch field, it can adapt to the pitch value between 0.15mm-0.4mm. It has excellent service life and stability, can maintain a good connection, and won’t be stuck with a PIN or broken needle.

In addition to battery quality, cell phone lithium battery testing must also consider how to increase battery output, reduce production costs, and maximize benefits. Under the high-frequency test, the average service life of the high current shrapnel microneedle module can reach more than 20w times. If the operation, environment, and maintenance are good, the service life can reach 50w times, and the shrapnel head has a self-cleaning design, which can maximize the use, and greatly improve the testing efficiency of mobile phone lithium batteries.

It’s that time of the year where a lot of car batteries are going bad.

A Toyota Corolla battery failed the battery test. There was also corrosion on the battery terminals.

You know the story – you wake up one morning, get ready for work, start your car and … nothing happens. A car battery going bad is a common occurrence, and one that is often easy to fix.

But if you want to avoid having one of those mornings where your car won’t start, getting your battery checked out regularly identifies problems with your battery early.

The battery helps start a vehicle, provides extra power when needed, and even helps certain computers run after the car is turned off.

Batteries should be checked as part of a normal oil change service. Following the battery test, you should receive information on the health of your battery, so you know if the battery will need a replacement in the near future.

Did you know the best way to test a battery is to take it to an auto parts store for a free load test?
