Lascells Battery Eliminator – Ending Dead Cells in Class! 

Anyone who has taught science knows the frustration: you’ve set up a circuit, grabbed a box of batteries, and… half of them are flat. Students get poor results, the lesson stalls, and the hunt for “good” cells begins.

The Lascells Battery Eliminator solves this problem brilliantly.

🔧 What It Is

A compact unit that provides fully regulated DC outputs at all the standard battery voltages:

• 1.5 V

• 3 V

• 4.5 V

• 6 V

• 9 V

• 12 V

The outputs are delivered via colour-coded 4 mm safety sockets, making it safe and simple for classroom use.

⚡ Why It’s Useful

• Reliable power – no more guessing whether a cell is alive.

• Electrolysis experiments – powerful enough to drive visible gas production.

• Battery comparisons – students can test circuits at 1.5 V, then step up to 3 V, 4.5 V, and so on without swapping cells.

• 
  Safety built in – overload and short-circuit protection avoids damaged kit (or blown fuses).

🧪 In Practice

With the eliminator, students can:

• Compare the brightness of bulbs at different voltages.

• Investigate how current varies in series and parallel circuits.

• Run electrolysis of water without the fizzing disappointment of weak batteries.

It’s a reliable module that makes practical work smoother, more predictable, and much less wasteful.

🌍 Bonus Benefit – Sustainability

By replacing endless disposable cells, the eliminator reduces classroom waste and highlights sustainability — an important message alongside the physics. It is far better than using rechargeable cells, as it is always available rather than finding dead cells that missed recharging. Cheaper too.

🎓 Teacher Takeaway

No more dead cells, no more wasted time. Just solid, safe, repeatable experiments that let students focus on the science instead of the batteries. It's far cheaper than a power pack, and it's much more compact. There is not much to say against it, it has become an essential part of the kit of the lab.
