Lithium-ion tool batteries are safest when charged with the charger approved for their exact battery platform, in a visible, room-temperature location away from heat and flammable materials, and stored dry with a partial charge when they will sit unused. Stop using any battery that is damaged or behaving abnormally. These steps apply on construction sites and at home, but the battery manual and local fire, electrical, and workplace rules take precedence.
What do I need before charging or storing a tool battery?
Before connecting a battery to a charger or putting it away, identify its platform and check its condition. Use the charger supplied with the battery or one the battery manufacturer specifically approves for that exact platform. A plug that fits is not proof of electrical compatibility: using an unsuitable charger can create a fire risk. Health Canada recommends using the original battery and charger, and contacting the original manufacturer or retailer for replacement equipment; Milwaukee’s safety instructions likewise say to “Recharge only with the charger specified by the manufacturer.” See Health Canada’s lithium-ion battery safety guidance and the manufacturer’s power-tool safety instructions.

- Read the battery and charger instructions. Follow their requirements for compatible equipment, temperature, charging, and long-term storage. General safety advice does not replace instructions for a particular model.
- Inspect the battery. Do not charge or use one that is swollen, dented, cracked, leaking, unusually hot, or otherwise damaged. Check for a changed shape, odor, hissing, or other unusual behavior as well.
- Choose the charging location. Use a stable, dry, room-temperature surface where the battery can be seen. Keep the setup away from flammables, heat sources, and exits; do not charge on a bed, couch, carpet, or other soft surface that can hold heat.
- Clear the storage area. Choose a cool, dry location away from direct sun, extreme temperatures, combustible materials, and loose metal objects that could bridge the battery terminals.
In a workplace, these precautions are a starting point, not a substitute for site requirements. The Canadian Centre for Occupational Health and Safety (CCOHS) notes that its workplace guidance does not replace manufacturer instructions or legislation. Employers and workers should also follow applicable occupational-safety, building, electrical, and fire codes in their jurisdiction.
How can I charge a lithium-ion tool battery safely?
Charge with the approved charger in a suitable, visible location, and stop at the charging endpoint specified by the manufacturer. Keep the battery on a stable surface that does not trap heat, and do not leave charging batteries unattended or on a charger longer than the instructions allow.

- One-Handed Loading - Keep one hand free with a 1/4 in. hex chuck that accepts 1 in. bit tips
- Check the battery and charger. Do not charge a battery with mechanical damage or signs of failure. Confirm that the charger is specified or approved for the exact battery platform; do not rely on a connector fitting. Use charging equipment that meets applicable electrical requirements. CCOHS recommends recognized Canadian certification marks for charging equipment in its Canadian guidance, but certification and code requirements vary by jurisdiction.
- Let a cold or hot battery return to a suitable temperature. Charge at room temperature. Health Canada says not to attempt charging below 0°C; CCOHS similarly advises against charging below freezing unless the manufacturer permits it. Do not recharge a very hot battery. Follow the model’s instructions rather than assuming all batteries share one temperature range.
- Set up a safe charging area. Place the charger on a stable surface with airflow, where the charging battery remains visible. Keep it away from combustible materials, direct heat, and exit routes. Avoid soft furnishings and other surfaces that can retain heat.
- Connect and charge according to the manual. Do not modify the charger, battery, or connection to make incompatible equipment work. If the battery or charger behaves unusually, stop charging when it is safe to do so and follow the manufacturer’s guidance.
- End charging at the recommended point. Remove the battery or disconnect the charger when the instructions say charging is complete. Do not leave a battery on the charger for extended periods unless the manufacturer explicitly allows it.
- Store the battery appropriately after charging. If it will not be used for an extended period, follow the long-storage guidance below rather than assuming a full charge is best.
For a worksite charging station, keep the area orderly and visible so a problem is not hidden behind tools, materials, or equipment. The location should not block an exit, and it should comply with local site and electrical rules. CCOHS’s workplace guidance discusses charging hazards and fire controls; consult its lithium-ion battery charging guidance alongside the employer’s procedures.
Does a lithium-ion tool battery need to be fully discharged before recharging?
No. Hilti’s battery guidance says lithium-ion batteries do not need to be fully discharged before charging; partial charge cycles do not create the old “memory effect” concern associated with some other battery chemistries. For ordinary use, recharge according to the battery and tool instructions rather than deliberately running the battery flat first. Hilti’s battery and charger guidance is platform-specific; use your own battery maker’s instructions for model-specific recommendations.
How should I store lithium-ion batteries between jobs?
For routine storage, keep tool batteries dry, cool, protected from impact, and away from heat, direct sun, flammables, and loose metal. Prevent crushing or puncturing, and avoid placing heavy objects on top of batteries. A case or the original packaging can help protect batteries from impact and terminal contact, but it does not make a damaged battery safe or fireproof.

- Keep terminals from touching metal. Store batteries so loose screws, nails, keys, tools, or other conductive objects cannot bridge their terminals. Health Canada recommends a protective non-metal case for carrying batteries; CCOHS also recommends original packaging or a case for storage.
- Choose a dry, cool place. Avoid direct sunlight, heat sources, temperature extremes, and damp conditions. There is no single temperature range that applies to every tool battery, so follow the battery manual. Hilti gives a storage range of -4°F to 104°F for its own guidance; that figure is not a universal limit for other brands.
- Protect against physical damage. Keep batteries from being crushed, punctured, dropped, or buried under heavy materials. Do not stack heavy objects on them.
- Separate them from combustibles. Store away from flammable liquids, combustible building materials, and other sources of fuel. Do not treat a storage case as a substitute for a suitable location.
- Check stored batteries periodically. Look for swelling, cracks, leaks, unusual heat, odor, or other changes. If a battery appears damaged, take it out of service; do not return it to charging or use.
On a construction site, avoid leaving batteries in direct sun or in places exposed to heat extremes, impact, water, or loose hardware. The safest arrangement depends on the battery instructions and site conditions. Workplace charging and storage arrangements may also be governed by local fire, electrical, building, and occupational-safety requirements.
What charge level is best for long-term storage?
For extended storage, general guidance is to leave a lithium-ion tool battery partially charged, not full or empty. Health Canada recommends about 50% charge for batteries not in use for long periods; CCOHS recommends a 30–50% range, checking every three months and returning the battery to about 50% if needed. Follow the battery maker’s instructions if they specify a different storage level or schedule.
For a practical routine, charge or discharge the battery to the level recommended by its manufacturer before putting it away. Mark the date of the check if that helps keep a group of stored batteries on schedule. Recheck about every three months under the general Health Canada and CCOHS guidance, and bring the charge back to the recommended level if needed. These are general recommendations, not a guarantee of battery life or a substitute for the manual.

Health Canada’s wording is direct: “Store lithium-ion batteries with about a 50% charge when not in use for long periods of time.” CCOHS gives the slightly broader 30–50% range. Both sources support periodic checks rather than leaving a battery forgotten for an indefinite period. See Health Canada and CCOHS for their respective recommendations.
What should I do if a tool battery is damaged, hot, or smoking?
Do not charge or use a swollen, dented, cracked, leaking, or otherwise damaged battery. Do not open it, attempt a repair, or charge a battery that has been submerged. If it becomes unusually hot, smells, hisses, changes shape or color, or starts smoking, treat that as a warning sign and follow the battery maker’s and local emergency guidance.
- If there is no smoke or fire: Stop using the battery and do not put it on a charger. Keep people clear and seek the manufacturer’s instructions or local waste authority guidance for safe handling and disposal. Move it away from combustible materials only if that can be done safely.
- If it smokes or catches fire: Evacuate the area and contact emergency services. Do not approach a smoking or burning battery to retrieve it or move it. Follow emergency responders’ directions.
- Do not put it in household garbage. Ask the manufacturer or local waste authority how to dispose of a damaged lithium-ion battery. Disposal rules and available collection services vary by location.
Battery failures can be violent. CCOHS warns that “Explosions may shoot parts of the battery over 18 metres (60 feet), causing multiple fires.” That distance is from CCOHS’s safety guidance, not a safe perimeter for every incident. If there is smoke or fire, evacuate and call emergency services rather than trying to assess a safe distance yourself. See the CCOHS guidance and the National Fire Protection Association’s lithium-ion battery safety information.

What are the most common battery charging and storage mistakes?
The main avoidable mistakes are using unapproved charging equipment, charging in a hot or obstructed location, ignoring a damaged battery, and storing batteries where heat, impact, moisture, or metal can create a hazard.
Recommended Free Tools
| Mistake | Why it matters | Safer choice |
|---|---|---|
| Using a charger because its plug fits | Physical fit does not confirm electrical compatibility. | Use the specified or manufacturer-approved charger for the exact platform. |
| Charging on a bed, couch, or carpet | Soft surfaces can hold heat and obscure a developing problem. | Use a stable, visible surface that does not trap heat. |
| Charging below freezing or while the battery is very hot | Charging outside permitted conditions can create a hazard or conflict with manufacturer instructions. | Let the battery reach the permitted charging temperature; check the manual. |
| Leaving a battery on a charger for an extended period | Some manufacturer guidance cautions against prolonged time on the charger. | Disconnect or remove it at the recommended endpoint. |
| Storing batteries loose with screws, nails, or other metal | Metal can bridge terminals and cause a short. | Keep terminals protected; use original packaging or a suitable non-metal case. |
| Putting a damaged battery back into service | Damage, swelling, heat, or leakage can signal a serious fault. | Stop using and charging it; consult the manufacturer or local waste authority. |
| Assuming one brand’s temperature range applies to all batteries | Storage and charging limits are model-specific. | Use the exact battery manual; treat published brand-specific ranges as limited to that brand’s guidance. |
What should I check before leaving batteries stored?
A quick check before a battery goes into storage helps prevent avoidable problems and makes long-term storage easier to manage.
- The battery has no swelling, cracks, dents, leaks, unusual odor, or other warning signs.
- The storage charge level follows the battery manual; for extended storage, general guidance is about 30–50%.
- The location is dry and cool, away from direct sunlight, heat, flammables, and temperature extremes.
- The terminals are protected from loose metal and the battery cannot be crushed or punctured.
- The battery is stored in its original packaging or a suitable case if that helps protect it, without treating the case as fireproof.
- A reminder is set to check long-stored batteries periodically; Health Canada and CCOHS guidance uses a three-month interval.
- Any workplace setup also follows the battery manual, employer procedures, and local codes.
The safest routine is straightforward: inspect first, use only the approved charger, charge in a visible and suitable place, stop at the prescribed endpoint, and store batteries partially charged when they will be unused for a long time. When a battery is damaged or acting abnormally, do not try to nurse it through another charge cycle.
