What Battery Does the Makita DUC353 Use?
The Makita DUC353 is a twin 18V (36V) tool that requires two Makita 18V LXT batteries simultaneously. Both battery slots must be filled for the chainsaw to operate. It uses two 18V LXT packs together for 36V, so no separate 36V battery is needed.
About the Makita DUC353
The Makita DUC353 is a twin 18V (36V) LXT brushless chainsaw with a 350mm (14 inch) bar and chain. It runs on two 18V batteries at once for 36V. Makita lists tool-less chain tightening, variable speed, a chain brake and a brushless motor, with a chain speed of 0–20 m/s and a 200 cm3 oil tank.
Compatible Batteries for the Makita DUC353
The DUC353 requires two Makita 18V LXT batteries at once. Makita’s manual lists packs from the BL1815N (1.5Ah) to the BL1860B (6.0Ah); we have no Makita guidance on mixing capacities. Here is how each pairing compares:

| BL1815 x2 | 1.5Ah | 0.35kg | Not Recommended |
| BL1820 x2 | 2.0Ah | 0.37kg | Not Recommended |

Recommended Battery
BL1860B (x2) — This tool requires two 18V batteries simultaneously. Two 6.0Ah packs give the most cutting per charge of the packs Makita lists.
Minimum Battery
BL1850B (x2) — Two 5.0Ah batteries will run the chainsaw, but by capacity, two 5.0Ah packs hold about 17% less charge than two 6.0Ah packs.
Battery Compatibility Notes
Important: This tool requires two 18V LXT batteries simultaneously. Both battery slots must be filled for the tool to operate. We have no Makita guidance on mixing capacities.
All Makita 18V LXT batteries use the same slide-on mount. Star Protection batteries communicate with the tool to prevent overheating, over-discharging, and over-current for optimal performance.

Battery sizing, runtime & troubleshooting
Recommended pack: Makita’s manual lists packs from the BL1815N (1.5Ah) to the BL1860B (6.0Ah); larger packs give more cutting per charge.
Compatibility caveats: 2× 18V LXT only — both slots must be filled. Makita’s manual lists packs from the BL1815N (1.5Ah) to the BL1860B (6.0Ah); we have no Makita guidance on mixing capacities.
If it won’t start or cuts out: Makita’s manual says that if the saw does not start, check that two charged battery cartridges are installed, and recharge them if the battery voltage is low.
Runtime: No official per-charge figure; chain speed 0–20 m/s, 200ml oil tank.
Versus the adjacent model: Unlike the single-battery LXT saws here (DSS611, DHS680), the DUC353 needs two packs — budget for a matched pair.
