Rated 1 out of 5Â by LazyJacques Replace charger first!!!
The chargers that were sold initially with the 48V mower are defective. They will overcharge the battery and destroy it, usually within a year or two of purchase. I have just gotten off the phone with Ryobi at 1-800-860-4050. If you own a charger with a FLAT LED light (as opposed to a domed one), they will ship you the improved charger and a replacement battery FREE of charge.

I purchased this replacement battery just a little over a year ago. I've been very careful to keep it charged and out of the weather. It ended up bursting inside of the mower leaking battery fluid everywhere. The worst part is that it's no longer covered by the warranty just like the last one that failed right after the one year mark.

Rated 1 out of 5Â by TryingToBeResponsible So much for that.
Haven't purchased the replacement battery yet, but the original battery pack from March 2012 swelled up and leaked today. Ryobi said to take it to Home Depot, and Home Depot said send it to Ryobi (because they don't do anything after 90 days). Not exactly stellar customer service. Ryobi says I have the updated charger, so all they could say is that my failure is "unusual". Doesn't keep me from having to spend $130 on a battery of dubious quality, though. Not very happy, and I'll remember this episode when considering future tool purchases.
Oh, and since I'm not getting warranty support, I decided to see what's inside. See pic for one of the two batteries in the pack. Note how the top is bulged upward.

I had the same battery problem as a lot of people here. Called Ryobi and told them my batteries were dead. The rep asked me to look at the LED lens on my charger. He said that if it is flat, it is a defective charger. He is sending me a new charger and battery - no charge. The charger with the domed LED lens is OK. If you have a flat lens on the charge indicator on your charger, call Ryobi and get a new battery and charger.
He didn't even ask me for purchase information so, even if you think you are out of warranty, I would try this.

Rated 5 out of 5Â by Flash Ryobi replacement battery
I've owned my Ryobi lawn mower for over 2 years. Since I have to mow about 5000 sqft, I had to mow my lawn in 2 sessions, but lately I found myself in my yard mowing my lawn more often than I really wanted to. I purchased a battery replacement which quickly reminded me I don't have to live in my backyard in order to have a manicured lawn.
I'm very happy with the replacement battery. I was able to mow more than half the lawn in just one session and since my old battery still holds a charge, I was able to do my whole property in just one outing.
