Thanks for the link to the Nissan Leaf forum. That was me, and I've been looking for that info for a couple days now! Forgot I made that post. Anyway, I'm in the market to replace the LiFePO4 batteries I installed in my CMM1200 back in March 2012. I had decided to not pamper them in any way, so they've been charged by the stock B&D charger and the mower has been sitting in the very hot heat here in Houston and also the chilly winters. Now it can mow only about 1/4th the grass it used to.

The batteries I bought 7 years ago don't seem to be available anymore. I'm zeroing in on this as a current replacement:

The down side is that, with a charger and shipping cost, it'll be about $440.

some might not work if you run in series, or, you need a special unit?, proceed carefully!

this one seems to be able to run up to 3 in series. https://relionbattery.com/products/lithium/rb20-x

not sure on any of these - maybe contact them?; https://www.lithiumion-batteries.com/ or https://www.powertechsystems.eu/hom...20ah-12v-lithium-ion-battery-pack-powerbrick/ or https://www.ebay.com/itm/12V-LiFePO...876970?hash=item3d8bf1aeaa:g:uHwAAOSwGBxc7X3i or https://greenlifebattery.com/product/12v-20a-lithium-ion-battery/

these claim to be replacements (gel) for your mower; https://www.mightymaxbattery.com/p3517063/12v-18ah-gel-battery-for-black-decker-cmm1200-mower.html

ouch - bet you paid a lot back then, too bad you didn't get more life outta them. Still, not 'horrible' I guess.

They were $350 back then. I probably should've gotten a dedicated charger but other things, like mower storage conditions, couldn't be helped.
I'll update this thread when I settle on a new battery system and get it installed.
