A very good Ryobi battery
This battery provides extra power for my Ryobi grass trimmer...the trimmer will run for a longer period of time. It works very well. It will charge up to full charge in about 2 hours after it is totally discharged. It has 4 lights built into it to show the amount of battery life left when using it. I highly recommend it.

Ryobi 40 volt 2Ah battery
I made a mistake and ordered without checking further. I just assumed that I was getting the 2.6 Ah like I already had. However, the price was right and the product is smaller & lighter than the two that I have which do not accept a charge any longer. Time will tell, but it should be a good backup while the main battery is charging.

Ryobi OP40201 2ah 40V Lithium-ion battery
Great battery--smaller and much lighter than the original that came with my blower, but seems to last just as long as my old, heavier battery. Only wished they would have packed it better, as it was flopping around in the box (no packing whatsoever). But it works, so I am happy.

Charged up & seems to have good run time! Thanks!
Still too soon to tell for sure, but so far working well. I have had troubles with these 40 volt batteries in the past.

Great source of Li-ion cells!
I have purchased over 40 of these 40 volt 4 amp batteries in the past three weeks. Some were new, some used, and some defective. There are 20 cells in each battery, so I have approx. 800 cells to build a power wall. Of the 800 cells, 20 were bad. That's 2.5 percent! 97.5 percent were excellent! Each cell is 2 amps with maximum current of 20 amps. Most are Samsung. .
