Today we're checking out batteries
Previously on Gwangalli
When we compared basic models, the batteries showed surprising results
defying everyone's expectations
(Comparing high-performance batteries!) To learn the differences between premium and standard batteries
We also included Daiso Neo Cell, the winner of the first round
(Bexel Platinum, Energizer Max Plus, Duracell Ultra, Daiso Neo Cell) Today's products
(Tidbits, capacity test, duration test) Today's test
(Bought them all myself today~) All batteries were purchased by us for this test

(Review with self-purchased products!) Appearance comparison before exploration
First up is Bexel Platinum
Based on a 20-pack, it's 595 won per battery
Next is Energizer Max Plus
Based on a 20-pack, it's 845 won each
Third is Duracell Ultra
Based on a 20-pack, it's 595 won each
Last, Daiso Neo Cell
Based on a 20-pack, it's the cheapest at 150 won per battery
I also measured the weight of each battery
Duracell and Daiso are a tiny bit lighter, with a 1g difference
So, what are the differences between these four batteries?
Let the test begin!
(Review with self-purchased products!) Battery tidbits
(Before the test starts!) Batteries with different types and names
(What are the differences between various batteries?) What differences do they actually have?
First, Let's compare disposable and rechargeable batteries
(Battery types) Generally, you can think of batteries as disposable
The most commonly used are AAA and AA
There are also various other types like coin, C, and D
And for rechargeable batteries, AA and AAA are the most used
(Battery's main component) What are the key differences in battery compositions?
Batteries are generally alkaline, lithium, or manganese
(Easy to find) Alkaline batteries are common in everyday life
(Long usage time) They have the advantage of lasting a long time considering their price
(High price) And lithium batteries, although expensive
(High voltage) perform exceptionally well, ideal for high-voltage devices
(Short usage time) Also, manganese batteries have the disadvantage of short usage time
(Low price) but they are very cheap
(Rechargeable batteries) Also, nickel-metal hydride is common in rechargeable batteries
They need to be fully discharged before recharging
to maintain their performance well
Here's a reference for the voltage change over time
for the most basic alkaline batteries and nickel-metal hydride rechargeable batteries.
Now, some questions about disposable and rechargeable batteries!
(Can batteries maintain their functions after being charged consistently?) Can rechargeable batteries maintain their initial functions?
(Life drops with charge count) Basically, rechargeable batteries have a set limit of charging cycles
As it gets closer to this number, the lifespan gradually decreases
So, you can't use rechargeable batteries forever
Second, AAA battery can work as an AA when used with foils?
When putting AAA battery inside, filling the space wrapped with a foil, makes it work temporarily
Third, wrong battery can cause malfunction?
A low output battery in an overloadable product can lead to breakdowns
And battery leak causes trouble occasionally
This is usually because of using disposable and chargable battery together
or when changing batteries partially
or using batteries from more than two brands at the same time
So, let's see which battery is for which product
First, for a low load products like clocks, remote controllers, and audio
a manganese or an alkaline battery is suitable
And for a middle load products like portable lanterns, toys, game players
I recommend a alkaline battery
Lastly, for camera flashes and door locks
A lithium battery would be good since they are high load products
Capacity test
(How to: Find a larger capacity battery when checking of each battery using the measurement equipment)
First, let's start after connecting four batteries to the device in a row
(After a while, the result?)
The measurement has finished
Bexel goes 1951mAh
Energizer goes 2275mAh
Duracell goes 2086mAh
and Daiso goes 1958mAh
The highest one is Energizer
(Review with self-purchased products!) Sustainability test
(How to: Find a one with a better sustainability using battery with a low/middle/high energy consumtion) When using a battery with from a low consumtion
to high consumption products
let me find the one with the best sustainability
First, the representative of the low consumption
A microphone
Let's put in a new battery and start
Time goes at the same time
and will keep them until they are dead
(Daiso's Neocell) After about 13hrs and 58mins
the microphone with Daiso battery shows a low battery sign
It is measured about 1.21V with the low battery sign on
And after keeping them running
About 14hrs and 17mins later
Bexel got the low battery sign
Bexel Platinum is measured 1.18V on the same basis
And as time goes by more
About 15hrs and 17mins later
Duracell got the low battery sign as well
On the same basis too, Duracell Ultra is measured about 1.20V
Lastly, about 15hrs and 37mins later
Energizer got the low battery sign
Energizer Max Plus is measured about 1.18V
It was Energizer which made the microphone work for the longest
When activating a microphone
Daiso discharged first
Energizer‘s running time was the longest
Next, for the representative of medium rate discharge products
The toys
We are putting in new batteries in each toy again
And starting them at the same time
The trains are running well
(Run time approximately for 9 hours) Approximately 9 hours later
(Gradually getting slower) The speed is slowly decreasing
(Daiso Neocell) Daiso’s train stopped at around 9 hours and 34 minutes
Daiso’s remaining battery is around 1.02V
The rest of the trains are still running
Next, Duracell’s train stopped at around 10 hours and 49 minutes
Duracell’s remaining battery is around 1.11V
Now there are only 2 left
Which one will last longer?
The time continues to pass by
At around 12 hours and 19 minutes, Energizer’s train stopped
Energizer Max Plus’s remaining bettery is around 1.07V
We will watch the only survivor, Bexel till the end
It is continuing to run well after 12 hours and 30 minutes
It continued to run
Until it stopped at around 12 hours and 48 minutes
Bexel Platinum’s remaining battery was around 0.95V
Bexel’s train ran the longest
When it was used for toys, Daiso’s battery discharged the fastest
And Bexel’s ran the longest
Next, to test high-rate discharge product
Door locks
We put in new batteries in the door locks
And we will turn it on while recording the number of times
We turned it on 3000 times in the same way
Now we are going to check the remaining battery mid-way
These are the remaining batteries after turning them on 3000 times
After the checking, to create the most realistic conditions
We let them naturally discharge
And after, we continued to turn them on while we recorded the number of times
After 3 days of manually working them
It’s almost over
We continued to use the door locks
And completed using them 10,000 times
First, this is the remaining battery after using 7,300 times
This is after 8,000 times
And finally the remaining battery after 10,000 times
The results of manually turning them on 10,000 times
(At the limit of manual work) It will take a long way to completely discharge
Because further manual work is too difficult
We set them up to work automatically for 4 days
And after 24 more hours of turning them on
These are the remaining batteries of each one
And this is the remaining after 48 hours of use
Lastly, this is the remaining after operating the door lock for 72 hours
And, when we turned the door lock on for one more day
we could see that the daiso battery ran out first
the remaining was 0.80v after it has ran out
When we turned it on for three more hours, back cell had ran out
The remaining was 0.94v
We had the remaining two locks on for five more hours
and the Duracell ran out
Duacell had left with 0.84v
The Energizer kept working for two more hours before it ran out
The remaining was 0.81V
That was a long test run of door locks!
Please check out the amount of time it took for each battery to run out
The Energizer battery was working for the longest
The final result of batteries
It took us one week to film this result of batteries
When we measured the batteries with the discharge 250mAh rate
the battery with the biggest storage was Energizer Max Plus
However, we used a store-bought measuring device
So the value might differ
And, we also measured the duration value of the batteries
The camera mic with low rate discharge
was on for 15 hours and 37 minutes with Energizer
It was able to be used the longest
and the shortest one was from Daiso with 13 hours and 58 minutes
And, when we had the batteries in a toy with moderate discharge rate
Backcell came in first place with 12 hours and 48 minutes
and the Daiso battery ran out the earliest with 9 hours and 34 minutes
When we had a door lock on until it ran out, which is a high-rate discharge product
Energizer was able to be working for the longest
while Diaso, again worked for the shortest time
However, this test was ran in a special condition with the purpose of a battery run out
and the hours of operation
may vary by the type of your door lock or the environment of use
Lastly, the cheapest battery per one battery compared to the price
was the Neocell from Daiso
