Power tools beta · DeWalt
Owners keep FlexVolt batteries because they power both 20V and 60V tools from one system, though many end up sorting out which cells last and which ones don't.
Owners are divided on battery life: some report a battery still going strong after nearly a decade of regular use with no bogging down, while others have had batteries fail or need replacing well before that.
Battery reliability is also split among owners. Several describe cells failing or losing voltage on the larger 60V tools while still limping along on 20V tools, and some have shifted back to plain 20V batteries after multiple 60V failures, while others report no problems at all.
Pick up to three. You get a page with just those, side by side, on the subjects owners raised.
Once the FlexVolt system settles in, owners describe the cross-platform trick, one battery running both 20V and 60V tools, as the thing that keeps paying off day to day. It becomes routine to grab whichever battery is charged and put it on whatever tool needs it, and some owners keep a mix of battery sizes on hand to match runtime to the job, pairing a smaller battery with a lighter tool and a bigger one with something that draws more power.
What owners adjust to is tracking which individual batteries are behaving. A battery that develops a weak cell can still run smaller tools while refusing to power a high-draw tool, so owners learn to notice when a battery that used to run everything suddenly can't handle the big saw anymore. Price is also something owners watch for: several wait for sales since batteries can cost more than the tool itself, and some point out that other line batteries are lighter and slimmer for jobs that don't need FlexVolt's extra capacity.
Owners describe a real split in how these batteries age. Some have had a single battery run for years without issue, including one used almost daily for a decade. Others have lost multiple 60V batteries to bad cells, usually blaming high current draw or letting the battery discharge too low, and have gone back to standard 20V batteries after repeated failures.
When a battery does fail, owners report DeWalt replacing it, sometimes after being asked to send photos, and in at least one case swapping a failed 12Ah battery for two smaller ones. The accounts behind battery longevity and tool durability are too few to say much more about the long run: three owners apiece, not enough to call a pattern either way.
Nothing has a clear majority against it yet. Counted from the owners who raised each subject, not from everyone. A subject is judged once at least 4 owners raise it.
14 more subjects came up from fewer than 4 owners each, which is not enough for a fair reading. To see how it stacks up, compare it with another machine.
