  • Quality
Love this replacement battery for my Hart lawn mower. I have a 4 that doesn't last long enough to do my whole yard,got this and it has plenty of life left over doing my whole yard. I don't even use the 4 amp anymore. You won't be disappointed. It's worth th money.

  • As advertised
I received the used battery as promised and it has come in handy with my new battery operated lawn mower. I have two batteries and my mowing time has doubled.

  • Hart Battery
This battery quit charging on September 2, 2023, and I contacted the Hart company for support and warranty service. The battery was only 3 months old. Here it is October 13, 2023, and I'm still waiting for help. Worst company to deal with. I have had 5 different customer service personal contact me and they wanted to have the same questions answered. One hand doesn't know what the other hand is doing. Finally received a replacement battery on October 17, 2023. I do regret purchasing anything from this company. ... show more

  • You can't get your money back.
My battery arrived in a box, but the battery container inside looked like it had been dropped several stories to the concrete below. It would not charge and demonstrated a fault. I applied to return it, followed instructions, and shipped it. Six months later, my account shows the approval for a return, but nothing else. No money. The online help is circular and keeps you going around from menu to menu and back again. There are no phone numbers, email addresses, or forms to post a direct complaint. ... show more

  • Worth the investment
Works as well as I expected it would. Sadly, this battery costs as much as the mower.

  • Just like the original
I brought this because my lawn is a little to big for one charge that the battery came with a mower. Perfect!!! I am very happy with this battery!!! Had to charge it when it first came but it lasted just like the original! Identical!! Get purchase!! If you need a backup battery for your electric mower, this will not disappoint! ... show more
