Customer Reviews for RYOBI 40V Lithium-Ion 7.5 Ah High Capacity Battery

[This review was collected as part of a promotion.] Works just like a battery. Just like it is supposed to.

Monster of a battery. Charges fast in the charger. Is nicely balanced which is nice because of how big it is so it sits nicely in the tools.

Extended the run time of my brushless leaf blower by 100 percent.

I received two of these battery packs with my RY408100VNM snowblower. When used in my Ryobi 40 volt attachment capable string trimmer one lets me edge and trim all of the lawns I mow. This task usually takes a 4 ahr. and most of a 6 ahr. battery packs.

Can’t go wrong with Ryobi products.

[This review was collected as part of a promotion.] This battery I got with the purchase of the leaf vacuum and leaf shredding. Bag is big enough to do a large area before you have to empty it.

[This review was collected as part of a promotion.] i wanted extended time to get my yard work done without stopping to recharge the baTTERY

[This review was collected as part of a promotion.] Runs a long time on a charge and charges fast. I will buy 2 more in the near future. These work a long time in my other Ryobi tools. Buy it you won't regret it!

All my tools are Ryobi and I like the versatility of the batteries which you can use for different kinds of tools. This specific battery is just a back up for my Ryobi lawnmower. It’s great!

Works and lasts a long time.

Great battery, very large. It doesn't fit in many of my 40 Volt tools but I bought it for the portable Inverter power source so for that purpose I give it 5 Stars.

Lawnmower needs this big battery. Now I have 2 and can cut all the yard!

Great battery! Now I can do my lawn with just one battery.

While I like the idea of going battery operated, the biggest battery made by Ryobi only last 15 mins for my leaf blower. Then 3 hours to charge. It’s good while there’s power.

[This review was collected as part of a promotion.] I brought it 2 months ago. I really like it. I work long time. I recommend for everyone how like long work.

I get about 34 to 36 minutes out of a battery. So it takes me two batteries to mow my yard. You cannot immediately put a battery back on charge after it discharges, the batteries are too warm to stay on charge. So if I do need a third battery (this has happened once), I have to put it on charge after the second battery has discharged and the first battery has sufficiently cooled to allow it to be put back on charge. Fortunately, I don't need it fully charged to finish mowing when that happens (again not often). But I'm not sure of the effect of partially charging a battery and then using it, on battery life.

Great a few weeks in

This thing goes forever! Love it

Works well so far. Last charger died within a year. Will see how long this one continues to hold a charge. This battery is huge and heavier than others.

I bought 4 of the 7.5AH 40V for inverter generator for power outages. All 4 inserted into inv/gen ran my 18 cubic foot Frigidaire ref/freezer ( purchased winter of 2017 energy efficient model) for a continuous test time of 14 hours and 9 minutes, during which I opened the fridge door 3 times and the freezer door 4 times briefly. Oddly my repeat test using 4@ 6AH 40V did not meet the same output per AH ratio I had calculated and expected. For some reason the output draw % increased more than anticipated considering running 1st test total AH of 30 and 2nd test total AH of 24. I was expecting the 4@6AH to run for 28.3 minutes per AH as that is what I got using the 4 @7.5AH. I discontinued test seeing such and increase in the draw%. 4@7.5AH ran 8000BTU AC on low continuous with thermostat set on high to keep compressor running, low fan and it ran for 2 hours and 8 minutes.

performs as expected. it would be great if they were stocked in the store instead of having to order them on line!
