What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Stop the tool when the battery is depleted or the tool starts slowing down; remove the pack rather than forcing the work to continue. If you have a charged battery that the manufacturer lists as compatible with your exact tool model, swap it in. Otherwise, charge the pack with its specified compatible charger and pause or switch to another suitable tool while it charges.
What to do right now
- Stop and remove the battery. If the tool has slowed or is labouring, do not keep pushing it through the work. Makita Canada advises removing the pack when this happens. Follow the tool’s instructions for removing it safely.
- Check for a charged spare. Confirm that the spare is listed as compatible with your exact tool model and battery platform. A pack that fits physically is not necessarily approved for that tool.
- If there is no compatible spare, charge the pack as instructed. Use the charger specified for the battery and follow both the pack and charger manuals. If the manufacturer’s guidance for that battery says to let a hot pack cool before charging, do so.
- Use the waiting time safely. Pause the job, or switch to a suitable corded tool or another tool with a compatible charged pack if one is available and appropriate for the task and worksite. Charging still takes time; a different charger or an unapproved pack is not a safe shortcut.
How to check whether another battery will fit
Use the tool model number and the battery system—not appearance alone—to confirm compatibility. Check the tool manual and the battery maker’s compatibility list, and verify the charger separately. Battery platforms are brand- and system-specific; compatibility within one platform does not imply compatibility with another.

For example, Milwaukee identifies M12 packs for M12 tools and chargers, M18 packs for M18 tools and chargers, and MX FUEL packs for MX FUEL equipment and chargers (Milwaukee Tool battery and charger guidance). Bosch describes its POWER FOR ALL compatibility within that battery platform and its participating alliance (Bosch DIY POWER FOR ALL system). These are examples of their respective systems, not a cross-brand compatibility rule.

Check the exact model, not just the brand
Compatibility can vary even among tools from the same maker. Dremel, for instance, lists its B20V20 battery for the US20V cordless compact saw and MM20V oscillating multi-tool. Its compatibility information also identifies B815-01 and B816-01 packs for models 8240, 8250 and 8260, while excluding model 8220 (Dremel battery compatibility list). Confirm the precise pack and model before swapping.

Charge the battery safely
Use the charger approved for the specific battery system and follow the instructions for both products. Do not force an incompatible pack into a tool or charger, or rely on an altered, non-genuine or otherwise unapproved battery. Makita warns that non-genuine or altered packs can pose fire risks and have unknown performance (Makita U.S.A. service FAQ). Metabo recommends original packs and chargers or those from its CAS partner system, warning that other systems can create safety risks (Metabo battery pack systems).
Battery care instructions can differ by product. Makita Canada’s guide advises letting a hot pack cool before charging and removing it when the tool begins to slow or labour (Makita Canada battery care guide). Follow the instructions for your own battery and charger rather than assuming every pack has the same charging or cooling requirements.

How to avoid another interruption
- Bring a charged spare that the tool maker lists as compatible with the exact model. Dremel recommends a second battery to reduce downtime, and its B20V20 product guidance says another battery can be used while one charges (Dremel 20V Max 2Ah battery product page).
- Before starting, check that the tool, battery and charger belong to compatible systems and that the spare is charged.
- Choose a pack based on the job as well as compatibility: capacity can affect pack size and weight. The manufacturer sources cited here do not establish a universal runtime, so estimate needs from the specific tool and work rather than assuming a general number of hours.
