Laser pen batteries and charger

The right batteries for your laser pen

Every laser we sell comes with its battery – and the Pro models with a charger – so you can use it straight out of the box. This page is for spares: a second cell for a long night of stargazing, a replacement after years of use, or a second PowerFox charger so you can charge at your desk, in the car or from a power bank. Every Pro laser comes with 1 battery; extra batteries can be added when you order.

Which battery fits which laser?

• 18650 batteries fit the full-size Pro models: G3 Pro, G1 Pro, R1 Pro and V1 Pro. Spares: PowerFox 18650 batteries (2-pack, 6800 mAh).
• 16340 batteries fit the compact Pro models: G2 Pro, R2 Pro and V2 Pro. Spares: PowerFox 16340 batteries (2-pack, 1800 mAh).
• The PowerFox charger is the same charger that comes with your Pro laser; it takes 18650 and 16340 batteries, one at a time.
• The laser pens X1, X2, M1 and Z1 use two powerful AAA batteries (included), and replacements are available in any shop.

Battery guide

Charging lithium-ion cells safely

• Use a charger made for 18650/16340 lithium-ion cells, such as the PowerFox charger supplied with your laser. It charges one battery at a time.
• Charge on a hard, non-flammable surface and do not leave charging cells unattended for long periods.
• Insert cells the right way round: plus to plus. Never use a cell with a damaged wrapper or dents.
• Carry loose cells in a case, never loose in a pocket with keys or coins.
• Take used cells to a battery recycling point; do not put them in household waste.

When is it time for a new cell?

Lithium-ion cells slowly lose capacity over the years. If a fully charged cell runs flat much sooner than it used to, or the dot looks weak straight after charging, it is time for a fresh one. For the pens, a dim dot simply means new AAA batteries.
