Advantages of Li-Ion Batteries
- No Memory Effect: Li-Ion batteries can be recharged repeatedly, when needed, without any decrease in performance.

Be aware of this when choosing your tools – the ones with integrated batteries have convenient little charging cords (like your cell phone), but you’ll have to replace the whole tool when it dies.
