Much better than the 6
This battery is a must if you've got the Hart 40v tools. the 6ah battery that came with my mower only powered it for half my lawn, so I bought this one so I could get the job done in one day. But, shocker, I got the whole lawn done in about an hour with this battery, and never had any drag in power like I did with the other one. Hopefully it keeps up, but it's already proven to be a great value, i just wish the mower came with this size to start with.

About time!
It works. Still trying to get a warranty or insurance refund on a bad battery (6 Ah). This 7.5 Ah battery should have been what all HART self-propelled electric mowers came with!
Verified Purchase
Bigger battery and cheaper than smaller battery in store. Great price compared to the physical store. Hart is a quality product have had it since first came out and finally had a battery quit working so decided to get another one.
