The other day, I tried to use it and charged it, but the lamp wouldn’t light up?
That’s strange, it was working yesterday…

I happened to have the latest 22V model, so I used the cooling jacket that day.
The next day, I charged it again just to be sure, and the lamp started flickering.
“Ah, it must have been a poor connection.”

I charged it fully.
But when I unplugged the AC cord, the lamp went out.
When I plugged the AC cord back in, it flickered at 20% and started charging again.
No matter how many times I tried, it wouldn’t come back to life, so I thought it had passed away.

Since I’d be in trouble without a spare, I went ahead and bought another 22V.
But if it breaks again around next year, I’ll be saying goodbye to Bartul for good.
It’s been a while since I’ve encountered a battery that dies this quickly. <\/p>\n\n\n\t\t

THE design! That was it.
I had a faint hope that maybe there was some kind of switch on the back?
But that was way too optimistic… <\/p>\n\n\n\n

<\/div>\n\n\n\n

It’s frustrating that it charges slightly? <\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

When I plug in the AC cord, it starts charging from 20% to full every time. <\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n


Interestingly, even after it’s fully charged, the switch doesn’t work at all. When I unplug and plug it back in, it starts again from 20% flickering.
I’m so frustrated that I’ve tried it over 10 times now, but it’s not working. <\/p>\n\n\n\n

I’ve always been a genuine battery person! Kyocera’s reliability has gone down. <\/h2>\n\n\n\n
\"\"<\/figure>\n\n\n\n

Basically, I’m a genuine battery person.
I have the impression that those suspicious batteries sold on Amazon and such break down quickly.
So even though it costs more, I’ve always had the policy of never using anything but genuine batteries.

Given the short usage period and number of charges, and that I haven’t been rough with it, this failure is a bit shocking.
Looking at the Amazon reviews, it seems there are similar cases. <\/p>\n\n\n\n

It seems like there are many people who have had it even worse than me.
Looking at this, you’d think it’s just a matter of luck, right? No, no, that’s not it.

So that’s why I bought the latest 22-volt model, and I really hope this one lasts longer. <\/p>\n\n\n\t\t
