HART 40-Volt 7.5 Ah Lithium-Ion Battery

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.

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!

This battery is amazing. it lasts a very long time. i can do the front yard and the backyard, and only one bar goes down, so i would definitely recommend this brand and the battery.

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.

Super fast shipping! Very good product quality at a fair and just price. Very good seller communication. Product worked out perfectly. I highly recommend this product for all your 40V Hart Products. Thank You Walmart for yet another pleasant buying experience.

I bought this battery because the two 6Ah batteries were not enough to cut both front and back yards if the grass got high. Surprisingly, this 7.5Ah battery covered both of them. I will say that there has been a bit of a drought, so that may be huge factor. Nevertheless, 3 batteries should suffice now.

Ordered to add to my Hart Lawnmower, purchased over a month ago. Mower came with a 6ah 40V battery, but can't even do front and back yard on a single charge with that battery, had to charge it 5 times). Ordered the 7.5ah 40V battery, can now do front and back yard. Do front yard, recharge both batteries and do back yard.

Overall, the batteries are ok. However, the battery life has been very disappointing. This was a replacement purchase as my previous purchase lasted just over 6 months before it would no longer charge.

This battery sucks purchaed it only a month ago and it does not work. After just a few uses. I made sure I stored the battery in the garage in the dryer cool place. To make matters worse I cannot get through to hard customer service to get a replacement. $140 for battery do not waste your money

We purchased a weedeater, and it only ran for about 30 mins before the motor started smoking and weedeater stopped working. We returned and got a new one, and it was done the same thing. very dangerous. The battery will only stay charged for about 20 mins before you have to switch it out with a charged battery. Dont waste your time or money with this battery or weedeater
