Has anyone noticed on 9ah batteries the little silver terminals on the top? They don’t seem to be on my older 9ah battery. Any ideas what this is for?

Old batt at tip, new below –

DeWalt switched from 20700 battery cells to 21700 battery cells now that they are more readily available.

The 9.0ah now uses the latest battery cells, just like the 12.0ah. This is a good thing. It is a rolling change that began happening in quarter 2 of this year.

@The.Handyman will/do kits sold before the new battery came out start shipping with the new battery?

Yes, everything is getting transitioned over to this 21700 cell 9.0ah battery.

My FlexVolt cutoff saw came with the 21700 cell 9.0ah batteries.

@The.Handyman wow cool. Any power difference between the new 9’s and the 12’s?

There may be under heavy loads on tools that have high power consumption.

Hard to measure just how much.

I wouldn’t think there is any power difference if both use 21700 cells. Runtime obviously yes, power no. Metabo claim something like 3400w of power from tbeir 2x18v 8.0 21700 LiHD batteries.

The newer 9.0s are reasonably heavier than the older 9.0s… I just got one of mine replaced under warranty and received the new type. Old one weighing in at 1292 grams… New one 1458 grams.

Just ran them thru the mower..Old one dropped a level on the power gauge quicker but new one lost all 3 bars of power 1st. Was it’s 1st use tho, so might need to run it in more before it reaches max capacity.
