Can this 20v 8ah battery charge with the dewalt dcb115 charger?

All of the Dewalt 20V Max chargers should be interchangeable. I have a DCB107 charger and the DCB 208, DCB203 and DCB207 batteries I have all work fine with it.

I’m using 2 of these in my Dewalt lawn mower and they only last about a total of 30 minutes and then dead. Should these run longer??

Battery run time may vary depending upon factors including but not limited to charging conditions, usage of the tool, storage, environmental conditions, age, etc. Because of these factors, DEWALT is unable to provide a run time. Please contact DEWALT directly for further questions or concerns.

How long does it take to charge?

Not very long. Great battery, last long time

Can this fit a Dewalt 20v 1/2 impact that comes with the 4ah

Yes. Any 20v tool can accept any 20v battery. The 8ah will just be appt bulkier to handle the compact impact driver.

DEWALT 8.0 Ah, great choice , good value.

Genuine DW, charges on standard kit chargers , I should have ordered this before... good value, reasonable charge rate and beats dealing with changing out 1.3 Ah 'kit' batteries before the task is finished.

Powerful - holds the charge& gets the job done

Love this baby! It is heavy, but lasts in those outdoor tools. Leaf blower only ran 10 minutes plus. This one gets me through the job.

Larger internal bus conduit, great for operating larger devices like chopsaw or weedeater

Not too big, not too small. Runs weed eater for 1acre lot.
