Replacement Kobalt 40V Battery 6.0Ah for KB-540-06/KB440-06/KB240-06 Series | 40V MAX Lithium-Ion Battery | Compatible with 40 Volt Kobalt Cordless Power Tools | Fast Charging & Extended Runtime

I held off on reviewing this for a bit, as I wanted to see how the battery charge held over time. I'm happy to say that this battery is holding its charge and seems to have even better runtime than the OEM batteries when they were new. One battery has been able to cover my entire lawn, when previously I needed two to three batteries. I'm pretty pleased with the price, especially compared to what you'll pay for an OEM (if your local store even still carries them).

I have bought several 40 Max 6.0 Ah batteries works well last long and you can’t beat the price. Tom

Works like a charm ! Only 2 lights down for an hour of mowing. I like it !

Battery is perfect. Adds more mowing time to our mower. Well worth the money.

last less time than my old 2.0 amp battery

I ordered this battery to replace a bad one for a leaf blower. It has been good so far. Seems to be better than the original, although it is a bit pricey.

Great customer service! Battery wasn’t holding a charge... they sent a replacement overnight and it works great!
