Rated 2 out of 5 by from Not functioning correctly [This review was collected as part of a promotion.] Purchased with a trimmer & blower. Batter after 3 uses needs extended time to fully charge and half the time after 10 minutes it dies again. Worked good initially but now seems like a lemon.

Rated 1 out of 5 by from Does not last Tried to use this battery for the first time this season and it died shortly after starting. Thought that was weird but maybe it had just discharged a bit over the winter. Went to hook it up to the charger and get the flashing red and green lights. Tried 2 other chargers and have the same issue. Googling seems to suggest that the battery has a fault, so now I have a very expensive paperweight.

Hi I have a Ryobi auger with a 40 V lithium 4ah battery. I was wondering if the battery has to be completely dead before recharging? I know I?ll be able to recharge it but will it lessen the batteries run time while using the auger If charged early?

I have two batteries for my mower. I run one until the power runs out. Than I use my other one. Now when I had 1 battery i did charge after every use and that has only about half life on it. But I have had that battery for 5 years . It's much better if you have two.

Asked by: Kenneth
Should. Didn’t fit in my 14in chainsaw because the opening was too small. If your weedeater has the battery just slide on the bottom should be fine.

Should I keep the battery on charge until I need it?

Asked by: Darrell
No , for the simple reason as a firefighter lithium batteries when overheated which could result from being overcharged can create a fire which cannot be easily extinguished

I have an older model RY40805 snow blower. What battery will fit? The space it slides into is very narrow and one other 40V we have will not fit!
