Can I Charge a DeWalt 20V Battery on a 60V Charger?

Yes. Any DeWalt charger labeled 20V/60V MAX automatically detects the pack you slide in and charges a 20V MAX battery in 20V mode. The charger does not force 60 volts into a 20-volt pack. The DeWalt DCB118 8A Fast Charger, the most common charger in this category, lists 12V MAX, 20V MAX, and 60V MAX as supported platforms on DeWalt’s own spec page (Source: asia.dewalt.global DCB118 spec, verified 2026-09-24).

This is the single most repeated battery-charger question in DeWalt’s ecosystem. The confusion is understandable: 60V sounds like it would fry a 20V pack. The engineering says otherwise. Charger compatibility in DeWalt’s lineup is keyed by the pack, not by the number printed on the charger.

Why the voltage on the charger does not overcharge the pack

DeWalt’s FLEXVOLT system is built around auto-sensing electronics on both sides of the connection. FLEXVOLT packs contain two internal 20V cell strings that wire in parallel for 20V output or in series for 60V output depending on the tool or charger attached. DeWalt product manager Ward Smith stated in a 2016 trade-publication interview that FLEXVOLT batteries “automatically change voltage when the user changes tools” (Source: Contractor Supply Magazine, via search snippet verified 2026-09-24).

Chargers work the same way in reverse. A 20V/60V MAX charger reads the pack’s identity on insertion. A 20V MAX pack gets 20V charging voltage. A FLEXVOLT pack gets charged in whichever mode the charger and pack negotiate, typically 20V mode on multi-platform chargers. The identical connector rails on 20V MAX and 60V FLEXVOLT packs mean one charger receptacle serves both pack families (Source: SlashGear: Can You Charge A 60V DeWalt Battery On A 20V Charger?, verified 2026-09-24).

PowerToolBench’s read: the “60V charger” is a misnomer. It is a 20V charger that also speaks 60V. Your 20V pack never encounters the higher voltage.

Charger compatibility matrix (Last verified: 2026-09-24)

The directionality matters more than the voltage number. Chargers charge across the full range below their rated ceiling, while batteries have stricter one-way limits in tools.

Charger	Charges 12V MAX	Charges 20V MAX	Charges 60V FLEXVOLT	Output
DCB118 8A Fast Charger	Yes	Yes	Yes	8A premium / 4A compact
DCB1112 12A Fast Charger	DeWalt listed 20V+60V; 12V not listed	Yes	Yes	12A (highest DeWalt rate)
DCB1106 6A Charger	Yes	Yes	Yes	6A
DCB115 4A Charger	Yes	Yes	FLEXVOLT in 20V mode	4A
DCB107 2A Standard	Yes	Yes	FLEXVOLT in 20V mode, slow	2A

DeWalt official DCB118 spec and Ohio Power Tool DCB118 listing, verified 2026-09-24; DCB1112 via Home Depot Canada snippet, verified 2026-09-24.

The DCB118 is DeWalt’s current-volume 8A option at a $149.00 street price (Source: Ohio Power Tool DCB118, verified 2026-09-24, in stock). Its published charging benchmark: the DCB606 6.0Ah FLEXVOLT pack in 60 minutes. The DCB1112 at 12A is DeWalt’s fastest published rate for the 20V MAX and FLEXVOLT range, but it is a step up in cost and bulk that only heavy multi-pack users justify.

The reverse question: 60V pack on a 20V charger

Users ask this one less often, but the answer matters for anyone who bought FLEXVOLT packs before upgrading chargers. FLEXVOLT batteries are backwards compatible with most existing DeWalt 20V MAX tools and chargers (Source: DeWalt product manager statement via Contractor Supply Magazine, verified 2026-09-24). On a 20V-only charger, the FLEXVOLT pack charges in 20V mode.

What you sacrifice is time, not the pack. SlashGear’s explainer notes the 60V FLEXVOLT pack takes about 60 minutes on the all-purpose fast charger versus about 40 minutes for a 20V pack at the same point (Source: SlashGear, verified 2026-09-24). Drop to a standard 2A 20V charger and a 9Ah-class pack can exceed two hours. The battery-management system handles the rest.

Myth vs fact

Myth: “A 60V charger will push 60 volts into my 20V battery and destroy it.” Fact: FLEXVOLT-compatible chargers negotiate voltage with the pack before and during charging. The charger’s 60V mode is only offered to packs that identify as FLEXVOLT. A 20V MAX pack is charged at 20V with a current the charger sets based on the pack’s size class (8A premium, 4A compact on the DCB118).

Myth: “You need a separate charger for each voltage line.” Fact: DeWalt’s DCB118 covers 12V MAX, 20V MAX, and 60V MAX on a single charger with a 6-foot cord and an internal cooling fan (Source: Ohio Power Tool DCB118 listing, verified 2026-09-24). One charger for the entire DeWalt cordless catalog is the design intent, not a loophole.

Myth: “FLEXVOLT packs charge at 60V even on multi-platform chargers.” Fact: The DCB606 is sold as a 6.0Ah pack at 20V MAX and a 2.0Ah pack at 60V MAX: the same stored energy, reconfigured. Multi-platform chargers charge FLEXVOLT packs in 20V mode, which is why a 6Ah pack still takes 60 minutes rather than charging at triple voltage.

Myth: “Charging speed is the same regardless of charger on any pack.” Fact: This is the one place the myth is backwards. Charge rate is the variable. The DCB118’s 8A rate on premium packs is double the 4A of a standard fast charger, and the DCB1112’s 12A is DeWalt’s fastest published rate for the platform (Source: Home Depot Canada DCB1112 snippet, verified 2026-09-24).

Which charger to buy

Three cases cover almost everyone.

You own only 20V MAX tools and charge a few packs per session. A 4A charger is the right match. The DCB118’s 8A rate earns its $149 price only if you routinely cycle many packs per day and the saved minutes convert to work.

You own 60V tools, or you are adding your first one. Buy the FLEXVOLT-capable charger once. The DCB118 handles your whole kit: 12V MAX, 20V MAX, and 60V MAX FLEXVOLT on one charger, 60 minutes for a DCB606-class pack. If you are expanding into 60V tools and need a charger for the new kit, browse cordless power tools at Rockler (affiliate link) .

You own FLEXVOLT packs but only 20V chargers. You do not strictly need to upgrade. Your existing chargers charge FLEXVOLT packs in 20V mode. Upgrade when charge time becomes the bottleneck, typically the moment a second or third FLEXVOLT pack enters the kit.

For the full one-way rules on tools, not just chargers, see the DeWalt FLEXVOLT battery compatibility guide. The 20V MAX vs 60V FLEXVOLT voltage question is covered in depth at DeWalt 20V MAX vs 60V FLEXVOLT. If you are comparing DeWalt against Milwaukee before committing to a platform, the M18 FUEL vs FLEXVOLT comparison runs that decision. Our testing standards and spec-verification process are published in the methodology.

Frequently asked questions

Can I charge a DeWalt 20V battery on a 60V charger?

Yes. Any DeWalt charger branded 20V/60V MAX or 12V/20V/60V MAX detects the pack voltage automatically. The DCB118 8A charger is listed by DeWalt as covering 12V MAX, 20V MAX, and 60V MAX FLEXVOLT packs. Your 20V pack charges in 20V mode; it is not stepped up to 60V.

Will a 60V charger damage a 20V battery?

No. FLEXVOLT-compatible chargers identify the inserted pack and deliver the correct voltage. The charger's 60V capability only activates for a FLEXVOLT pack signaling 60V mode. A 20V MAX pack never sees 60V on the charge rails.

Can I charge a 60V FLEXVOLT battery on a 20V charger?

Yes, but slower. FLEXVOLT packs are backwards compatible with DeWalt 20V MAX chargers and charge in 20V mode. A large FLEXVOLT pack on a standard 20V 2A charger can take over two hours versus 60 minutes on the DCB118. You lose speed, not safety.

Does the DeWalt DCB118 charger work with 12V batteries?

Yes. DeWalt's DCB118 spec lists 12V MAX, 20V MAX, and 60V MAX as the three supported platforms. One charger covers the full cordless range.

How long does a 20V battery take on the DCB118?

DeWalt publishes 60 minutes for the DCB606 FLEXVOLT pack at 6.0Ah, which charges in 20V mode. Smaller 20V packs at 4A/8A rates finish faster: a 4Ah compact pack charges in roughly 30-40 minutes at the DCB118's 8A premium rate. Exact times depend on the pack's capacity and remaining state of charge.

Is the DCB118 worth buying if I only own 20V tools?

Only if you charge enough packs to justify the $149 street price. The DCB118's 8A rate materially shortens cycle time for crews charging many packs per day, but for a homeowner charging two or three packs per session, a 4A DCB115-class charger is the cheaper match. The DCB118 earns its price when a FLEXVOLT pack enters your kit.

Can a standard 20V battery power a 60V FLEXVOLT tool?

No. Standard 20V MAX packs cannot produce the 60V series output and do not seat in 60V tool compartments, which are keyed for FLEXVOLT packs. Only a FLEXVOLT pack powers 60V and 120V MAX tools. See the full one-way rule in the DeWalt FLEXVOLT battery compatibility guide.
