【3rd Upgrade】 6.0Ah 40V Replacement Battery for Greenworks 40V Battery G-MAX 29472 29462 29252 20202 22262 25312 Cordless Power Tools Lithium-ion Battery

I'm always a bit reserved with third party parts, especially batteries that could potentially ruin a device if not to standards. However, this battery fit and worked well both in the charger and the mower without any disfunction. The battery casing looks well finished without flaw and appears as durable as the OEM battery, but for a significant price reduction as compared to OEM.Update: After a couple of uses, the battery works well, but does not last as long as the OEM 40v 5 Ah battery. The power ran out at about 80 percent completion in very similar conditions. The OEM was able to finish the task a week earlier and still have about 1.5 bar remaining on the meter. I would estimate that this battery was more equivalent to a 4 Ah than the advertised 6 Ah. However, it did again fit and power well. I still am satisfied having this as a backup battery.

Matched perfectly for my model of leaf blower and weed eater. I was worried that it would fit but it's perfect. Glad I didn't have to go and buy all new equipment

I have the leaf and snow blower and this works in both to a degree. It works perfectly in the leaf blower, but in the snowblower, it releases itself and then the snowblower stops until you push it back in. You can hear it click in and lock, but it works its way lose again. My OE 4ah battery does not do this, so it is the battery and not the tool. Overall, it does last longer than the OE 4.0 battery does so I'm happy about that. Maybe I got one that's just out of specs, but I will use it for the leaf blower and as a second for the snowblower. Maybe I'll have to wedge something in it to make it stay locked in place.

Well I purchased this battery in October of 2023 and mowed the first time this month (April 2025) and the battery last 10 to 12 minutes. Thought maybe I forgot to fully charge it before I mowed. I just mowed a second time on a full charge and once again it lasted 12 minutes.The batteries don't last more than 50 charge cycles. The warranty means nothing since there is no way to contact the seller for their 18 month replacement!

Better than the factory original

Seems like a great replacement and much lower cost than OEM. It charges fine and works fine. Seems very similar in power, usage, charge time to old one, but hard to say for sure. Close enough for me

I'm not real big on most knock-off brands, especially when dealing with battery powered tools. That said, I was pleasantly surprised at this battery for the price. I hope I get several years you said of it

I have three different 40v Greenworks tools (Trolling motor, Snow Blower, 19' Lawn mower) and the battery would not fit unless modifying but cutting off two plastic channels. Worked once on snow blower for 5 minutes before draining and will not charge on any of my Greenworks chargers. Charger shows fully charged but it is not. The advertisement states it works on 60 different Greenworks tools (it doesn't) and also has a 1 1/2 year warranty (it doesn't and could not return to AMZ. Buyer beware.****** Update March 21, 2023 The seller reached out with apologies and full refund. It was mentioned that the batteries have been updated to correct previous issues. I have revised my review to reflect a seller who does back their product and warranty.
