40V Lithium-ION 4.0 AH Battery

Have only used battery 1 time. In this instance it oerformed well

Bought as a refurbished battery, working as new. The battery fits devices and charger as expected. Charges as well as a new battery. Performs like a new battery. A excellent value for the price paid. I hope to find such a great deal again.

Still using long lasting it

Product is as described. I find that all of these style batteries are way over priced but this was the best value out there and you always need a second one. If I run my leaf blow at the highest speed, the battery last about 20 minutes but goes considerably longer at lower setting, so find the lowest speed that is effective.

These batteries were delivered on time. They work perfectly. I don’t know why this order still reflects a delayed delivery. My husband is using them in his Ryobi tools. I think the UPS tracking numbers got mixed up; the original tracking number was not the one on the package when delivered.

wish they were cheaper. but they are alittle less expensive than the local hardware store.

Battery would not charge .... blinked Red and Green which means a defective Battery or Charger (The charger was fine since I had another 40V Ryobi which charged with NO PROBLEM.) : Internal electronic failure in the pack or a malfunctioning charger base. Returned to Amazon. Purchased a new one at Home Depot.

Amazons the best! Battery in stock delivered same day!!

Was shipped right away. Works as advertised. Happy it was not damaged, suggest some foam or bubble wrap around it in box.Otherwise, happy with purchase.

I had ordered the 40V 4.0Ah battery, and it worked out of the package. Because it was February, I didn't need to use it right away. Unfortunately, it wouldn't charge, and I wasn't aware of the problem until after the 30 day return policy. I wrote the vendor, and explained what happened, and they replaced it at no charge to me. I've been using the blower and trimmer with this battery since then, and it works perfectly. Things go wrong at times with everyone, but what a vendor does to fix it is what makes a company good or not. I would not hesitate to buy from this company again!

Delivered before expected date, very grateful for this. Easy to charge and can feel the power of the battery when its working. For now I have used it twice and did not have to recharge while in use. I have a large area to trim so I was pleased for now. Longevity & Battery Life will depend how I care for the battery. All in all, very pleased with the results.

This was an older purchase so this review is based on extensive use. This battery powers my Lawnmower. The Mower came with 2 2ahr batteries that lasted about 5 years before degrading to such an extent that they would not work in the mower anymore so I needed a replacement. This battery is a replacement. This battery is so much more powerful and longer lasting. I can cut my whole lawn with a singe battery where it took both 2ahr batteries before. If you need a 40v battery than I would recommend you obtain this kind.

Amazon will NOT stand behind this item. This battery lasted me for 5 months (approximately 10 mows) and will NOT recharge . Amazon does NOT stand behind this seller (Phanton Intl.) Contacted Phanton and they do not respond. DONT BUT THIS ITEM!!!
