Charge time by charger wattage
| Charger | Power | Full charge (0-100%) |
|---|---|---|
| Slow charger | 15W | 2 h 16 min |
| Standard charger | 25W | 1 h 21 min |
| Fast charger | 40W | 51 min |
Battery capacity: 24 Wh · Chemistry: li-ion
Seasonal tools like this one often sit unused between projects, so a standard charger overnight is usually enough; a fast charger mainly helps when you need the tool again the same day.
Expect anywhere from a lunch break to a couple of hours, depending on the charger you use.
With the fastest charger listed here (Fast charger, 40W) it takes about 51 min. With the slowest (Slow charger, 15W) it takes about 2 h 16 min. Compact 12V cordless secateurs deliver precision cutting power for pruning branches and shrubs in gardens.
Frequently asked questions
- How long does it take to charge a Cordless Secateurs Battery (12V, 2Ah)?
- From 0% to 100% with the standard 25W charger, it takes about 1 h 21 min. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
- Can I use a higher-wattage charger to charge it faster?
- Yes, as long as the charger is compatible with the device's connector and voltage. The battery's own charge controller limits how much current it accepts, so a more powerful charger reduces time mainly in the 0-80% range; above 80% lithium-ion packs taper the charge rate for safety regardless of charger wattage.
- Why does charging slow down near the end?
- Lithium-ion batteries charge at full power up to about 80%, then switch to a slower "taper" phase that protects the cells from stress at high voltage. That's why the last 20% often takes nearly as long as the first 80%.
- How is this charge time calculated?
- We divide the energy needed (24 Wh times the percentage you're charging) by the charger's effective power, which is the charger's wattage times the battery chemistry's real-world charging efficiency (85% for Lithium-ion (Li-ion / Li-Po)). The same formula powers both this page and our API.
