What does Vf in li-ion battery mean (Chinese Imitation Batteries)

[drakejest]

i have encountered a cordless tool that has weird markings on it



I dont intend on buying this tool but i could not figure out what this Vf rating mean, I know this just some marketing crap but it muust have some bearing on something. I just could not get it of my mind.

Could not find a definitive answer, Any ideas?

Just a name for one of their "standards", they're free to make up whatever name they want. Also, if it's not already obvious, that's definitely not a 22.8Ah battery, just take a look at the size of a Ryobi 9Ah to get an idea of how big it really is. (The picture looks like 4-5Ah at best.)

Violently flammable?

Surely it's just a model number?

Big clive had a 24V battery pack charger that said 24V-98Vf. But it was just 24V inside.
So that doesn't really add up with the 588 number here at all.

Here is one thats 98Vf and 12000H (mAh). The 12,000 at least could be viable, 2400mAh * 5 = 12000.
98 makes no sense at all though... peak 4.2V per cell * 5 = 21V

Violently flammable?

incidentally... when the look and price is good... look at the "Very feedback"... to see its "Very fake"

Is that lump of partially burned plastic the remains of that TA2110 charger?
Or is it what’s left of an exploded battery pack that you tried to charge with that charger?
Or maybe a combination of both items?
