to me any tool is good as long as it does what it does and survive that job

i always buy cheapest china no names ones unless the more exp ones give me superior performance - eg the riveter & tin snips

anyhow, this is my bulldog after 3 weeks. she's been a good pup. a lot of bruises. very powerful... just one regret... i bought it rm700 too expensive



btw, dun belip that hype over vibration control. it hurts. my right arm is full with salonpas after drilling about 20 holes @ 14mm / 75mm deep.

Didn't use dust collection cover? So much concrete dust of the tool.

Oops my bad.
The thick Battery at the left is clone 4AH.
The thin battery at the right is ori 2AH.

I have no test equipment to validate their capacity but the thicker battery does lasts much longer than 2AH on a circular saw.

If that 10pcs battery is 4ah, than should be correct. Given it run 5pcs series and 2 set of parallel.

You need some discharge device to check the capacity.

Next time kong liau, can just change the battery to higher capacity. 6ah possible. Even 9ah or 12ah. 

But you need to use the high discharge type.

I never like Stanley tools. Their finishing are rough and not fine. More to medium quality. The grip can give me high torque to push.

That clone battery probably not 4ah. Probably 1/2 of it only. There is no 4ah battery yet in the market.

the clone batt pack is using what cells? samsung?

Have to check with Yushin.

Depend how cheap. Those too cheap will just use non brand type. Which have short charge cycle or lower capacity.

Brand battery will be more expensive. If they want keep it low cost, they will use lower capacity and label it at 2ah.

But fake or Ori, they must use high discharge type. If not will over heat or catch fire.

No idea, didn't open the wrapping, the cells are wraped in brown paper.
The seller says its samsung cell but I dunno how to validate.

Used the clone battery on my circular saw, doesn't feel the heat at all, a bit warm only.
Never really put the battery under high drain condition, I don't have a grinder. 

There is 2 type of battery cell. Normal discharge and high discharge. High discharge battery can discharge as high as 10A. Without heat the battery. Or catch fire.

It is normally use on vaping device. So you want to buy this type of battery, look for vaping people. They sell 100% ori.

For fake battery to achieve higher Amp but using normal battery, they parallel it the battery. So your drill motor require 10A to run, 10/2= 5A each battery discharge. So it won't heat up the battery.

I open the paper wrapping and saw these numbers
A UHG9RX8
035850

No idea what it means

Capalang battery. 

Normally will print like UR18650NSX which is Sanyo battery. Or INR18650-25R5 which is samsung.

I guessed so with such low price

Ok la. seldom use.

Cheap ma.

rm120 for a OEM 4ah 18v high drain batt pack?

bosch "outlet price" is only rm210 for the same spec

luckily i opted bosch 18v platform

Doubt average users have access to those "outlets".
I'm lucky I got my bosch 4AH @ RM240 last time, thanks to voucher war of online vendors. 

it was on garage sales in LYN. dunno he is doing it now or not

i got my stocks liao. 6x 4.0ah batteries really last me about almost 2 days worth of cutting and drilling.

about 2 hours of non-stop grinding if use all. 

Wahhh thats a lot of batteries you need.
My 2 x 4AH I already fell very sufficient already. I think charge only once a month.
