I bought a new Ryobi One + and for the first two mows it was hard to know if it was actually on, as it was so quiet. On the third mow it became a lot noisier - sounding more like a traditional petrol mower. It has been noisy ever since. How do I go back to it being a quiet/noiseless mower ? I have a small lawn which takes no more than 15 minutes to mow, so I always have enough battery power and I mow it regularly on the 2nd to highest setting available, so the blades are never under pressure from the grass being too long.

Hi there,
my sisters and i put some money together and purchased my mum a Ryobi chordless lawnmower. Since mum already had a fair few of the other products. However. None of us thought of getting the battery pack for the lawn mower. When i look at the prices they are well into the $200 mark which currently non of us can afford. I had a quick look on Ebay and Gum tree and there are a few for sale however i am unsure if this is the way to go. Would anyone recommend buying that way as the cheaper option or steer well clear for the very reason i am dreading.

Any advice would help? :)

I am the original poster. I would be sceptical of second hand batteries as all batteries, including lithium-ion have limited shelf life, hence Ryobi only guaranteeing these batteries for 3 years. Also, if they've been completely discharged, this will negatively affect the electrlytics and hence battery life. Unlike ni-cad batteries, lithium-ion don't have a 'memory' and are best not be discharged to a low level. I would not buy second hand batteries for the above reasons as you can't tell how they've been used.
By the way, I purchased new batteries for the original 36V one+ mower, but this didn't help. I then purchased the " newly designed" 18V one+ mower, which has so far performed flawlessly.
