Light-Tech battery

Batter has an expected 10-year service life for the 700 Series LED medical and dental headlights.

SEBRING, Florida--Oxide-based Li-ion is the industry standard for portable battery power but is plagued by poor durability and safety issues.

The Li-Poly used in almost every LED medical or dental headlight has a typical service life of only 400 to 700 cycles with only 50% of it's original capacity left. If the cell has a normal life, most users will only see two usable years with their battery pack.

Nano-Phosphate Li-ion cells help solve these problems through advanced chemistry and quality cell construction. The solid laser-welded cells can survive abuse, even heating the battery to 250°. Penetrating the pack with a nail will not cause a safety hazard either.

The new battery pack has a service life of more than 7,000 cycles or more than 10 years of use. The Model 777BP battery pack is available from Light-Tech, and is compatible with the 700 Series of LED Illuminators.

"We never offered a Li-Poly battery option because we weren't willing to sell a product that would need to be thrown in the trash in a couple years," said Lance Giller Sr., president of Light-Tech.

"NiCd offered us good durability but suffered if stored for extended periods. Sstill most users experienced three to five years of useable life. The nano-phosphate cells have enabled us to attack what we felt was the worst aspect of the current generation of LED medical and dental headlights. Light output is very similar among the competition, and so are the battery packs. This has enabled us to stand out in a meaningful way, after all why buy a LED that will last 50,000 hours and spend nearly as much on a battery pack that will only last 3,000?"

LED Headlights for dentists, physicians, and surgeons have been evolving during the past several years. LEDs have been marketed as a more cost effective solution due to lower power consumption and long life. The cost of replacing a battery pack for a medical light can sometimes cost several hundred dollars. This cost of ownership goes unmentioned by most manufacturers. Many dentists and physicians become aware of this when they hit their second year of ownership.

Oxide-based Li-ion cells have worked for cell phones, digital cameras, and other electronics that get replaced frequently. A medical grade LED headlight is a piece of professional equipment and deserves a higher expectation of durability.
