Why Runtime Varies — and What You Can Do About It
Two pros running the same WorCraft 20V tool with the same battery pack can get very different runtime depending on how they work and how they care for their batteries. These tips will help you get the most out of every charge and extend the life of your packs over time.
Match the Pack to the Tool
Running a high-draw tool like a paddle mixer or angle grinder on a 2.0Ah pack drains it fast and generates excess heat — both of which shorten battery life. Match your pack size to your tool's draw:
- 2.0Ah — drills, drivers, light tasks under 20 minutes
- 4.0Ah — angle grinders, saws, everyday fab work
- 6.0Ah — paddle mixers, heavy grinding, extended sessions
- 8.0Ah — all-day high-draw use
Rotate Two Packs
The single biggest runtime improvement on a job: carry two packs. While one is in the tool, the other charges. You eliminate downtime and avoid running a pack to zero — deep discharge is one of the fastest ways to degrade lithium battery capacity over time.
Avoid Heat — Before, During, and After
- Before use: Don't charge a pack that's still hot from use. Let it cool to room temperature first — charging a hot pack reduces capacity over time.
- During use: If the pack gets hot to the touch mid-job, swap it out and let it cool before recharging.
- Storage: Never leave packs in a hot vehicle or in direct sun. Heat is the primary cause of lithium battery degradation.
Store at Partial Charge
If you're storing a pack for more than a few days, leave it at 50–80% charge — not fully charged and not fully depleted. Most WorCraft chargers will indicate charge level. A fully charged pack sitting unused for weeks loses capacity faster than one stored at partial charge.
Keep Contacts Clean
Dust and debris on the battery contacts reduce power transfer efficiency. Wipe contacts with a dry cloth periodically — especially in a stone or tile fab environment where silica dust is constant.
FAQs
Q: Can I use Makita batteries on my WorCraft tool to extend my runtime options?
A: Yes — the WorCraft One For All Makita adapter lets you run Makita 18V/20V packs on any WorCraft 20V tool. If you already have Makita packs, they become part of your rotation. See the adapter.
Q: How many charge cycles do WorCraft batteries last?
A: WorCraft 20V batteries are rated for [X] charge cycles before capacity drops below 80%. Proper care — avoiding heat, deep discharge, and overcharging — keeps them performing longer.
