Aside from the prohibitive initial cost, this is an excellent battery. The reviewer who gave this a 1 star rating and said it doesn't last as long as his 4ah battery must have gotten the wrong battery, because this 5ah battery is bigger and heavier, and definitely lasts longer than the 4ah battery. I have a Greenworks 80v mower, and this 5ah battery allows me to mow my entire yard (about an hour, nonstop) without needing a recharge. My mower came with a 4ah battery, which wasn't quite enough. Now I have a 5ah, 4ah, and 2ah battery, so I never run out of battery power (I run out of juice long before the batteries do... haha). My review is based on initial use... durability and longevity remains to be seen, since I've only had my Greenworks products for about 2 months. I have a Greenworks mower, blower, weed whacker, and chainsaw, and I am absolutely happy with each product, as well as the battery life. I highly recommend Greenworks products if you are looking for top quality.
