Leica introduced a new series of lasers in 2014, the Rugby 600 and 800 series rotating construction lasers. Both use the new lithium-ion battery compared to conventional alkaline or nickel-metal hydride rechargeable batteries.

Litium-ion (Li-Ion) batteries have the lowest cost of ownership of any type of battery, and can last for 5 years or more.

Alkaline batteries have the highest cost of ownership. Nickel-metal hydride (NiMh) batteries have a much shorter life expectancy that Li-Ion. Li-Ion batteries are unique because they can be charged in a short period of time. With the new Rugby 600 and 800 series lasers, 30 minutes of charge will keep the laser operating about a half of a day.

Li-Ion batteries can handle hundreds of charge and discharge cycles without degradation, unlike other battery types. Li-Ion batteries can be charged at any time. Recharging before the batteries are fully depleted does not create a memory effect or shorten the like of the batteries.

Lastly, alkaline and NiMh batteries will self-discharge faster than Li-Ion batteries if left in the discharge condition, these batteries can ruin a good laser, making for an expensive laser repair. The smart technology of the new Rugby 600 and 800 series prevents the Li-Ion batteries from going into a completely discharge state, thus minimizing the chances of capacity-loss or a major laser repair.
