Your complete guide to power tool battery care for Australian buyers.

Power tool safety gear: glasses, ear muffs, gloves, mask

Lithium tool batteries last longest stored at 40–60% charge in a cool spot, charged before full depletion, and kept off the charger once full. Heat is the killer — a battery left in a hot ute tray ages months in a single Australian summer day.

In this guide the team at PowerTools Australia breaks down everything Australian buyers need to know, with straight answers and current local pricing. When you’re ready, you can shop batteries & chargers with fast Australia-wide delivery.

The Heat Problem

Cells degrade rapidly above 45°C. Vans and ute trays hit 70°C+ in summer — store batteries in the house or an insulated box, never on the dash.

Charging Habits That Matter

Top up at 20–30% rather than running flat; lithium hates deep discharge. Pull packs off the charger when done unless your charger has a maintenance mode.

Storage for Weeks or Months

Store at half charge, not full — full-charge storage stresses cells and is the main cause of 'dead after winter' batteries.

When to Retire a Pack

Noticeably shorter runtime, heat during charging, or swelling means retirement. Recycle at battery drop-offs — never bin lithium packs, they cause truck fires.

Frequently Asked Questions

Should I leave batteries on the charger?

No — once charged, remove them unless the charger specifically maintains storage charge.

Why did my battery die over winter?

It was stored full or flat; both degrade cells during long storage. Store at ~50%.

Can I revive a dead lithium battery?

Deeply discharged packs are usually protected against recharge for safety — genuine revival is rarely safe or lasting.
