Who are you guys and why are you selling batteries?
I'm Kevin Tierney ; I've been a cameraman for 20 years. I have a production company in South Florida, KTI Video. I recently started shooting HDCAM & Varicam and found the camera used 40Wh of power (twice as much my BetaCam or DVCam). I was using 50Wh Hydrons at the time and found I needed at least twice that capacity, that meant twice the weight (a Hydron 120 weighs 5.5 pounds on an already heavy camera). So, I figured in this wonderful age of technology, there had to something better. I went looking and these batteries are what I found.
Why are they so inexpensive?
They are inexpensive, but they're not cheap! I offer these batteries factory direct, no middleman. They are built with name brand cells, and quality components. When it comes to power, a Watt Hour is a Watt Hour, your camera doesn't care but your wallet does!
Are your products guaranteed?
YES! We guarantee our products with the same industry standard warranty as other battery manufactures. We guarantee our products to be free from defects in workmanship and materials for a period of one year from the date of purchase. If the products are determined by us to be defective or fail to meet minimum published specifications, they will be replaced free of charge at our discretion .
Can I charge these batteries on other chargers?
Our batteries are designed to be charged on our chargers. The V-Mount series may be compatible on most other V-Mount chargers as long as the charger is Li-ion chemistry compatible. The 3-Stud "Gold Mount" type battery is not compatible with Anton Bauer chargers.
What is the difference between Lithium batteries and Lithium-Ion batteries?
There are several important differences. The practical difference between Lithium batteries and Lithium-ion (Li-ion) batteries is that most Lithium batteries are not rechargeable, but Li-ion batteries are rechargeable. From a chemical standpoint, Lithium batteries use lithium in its pure metallic form. Li-ion batteries use lithium compounds which are much more stable than the elemental lithium used in lithium batteries. A lithium battery should never be recharged while lithium-ion batteries are designed to be recharged hundreds of times.
What are the advantages of Lithium Ion batteries compared to other rechargeable batteries?
Lithium-ion batteries have several advantages:
They have a higher energy density than most other types of rechargeables. This means that for their size or weight they can store more energy than other rechargeable batteries. They also operate at higher voltages than other rechargeables, typically about 3.7 volts for lithium-ion vs. 1.2 volts for NiMH or NiCd. This means a single cell can often be used rather than multiple NiMH or NiCd cells.
Lithium-ion batteries also have a lower self discharge rate than other types of rechargeable batteries. This means that once they are charged, they will retain their charge for a longer time than other types of rechargeable batteries. NiMH and NiCd batteries can lose anywhere from 1-5% of their charge per day, (depending on the storage temperature) even if they are not installed in a device. Lithium-ion batteries will retain most of their charge even after months of storage.
So in summary, lithium-ion batteries can be smaller or lighter, have a higher voltage and hold a charge much longer than other types of batteries.
What are the disadvantages of Lithium-Ion batteries compared with other rechargeable batteries?
Lithium-ion batteries are more expensive than similar capacity NiMH or NiCd batteries. This is because they are much more complex to manufacture. Li-ion batteries actually include special circuitry to protect the battery from damage due to overcharging or undercharging. They are also more expensive because they are manufactured in much smaller numbers than NiMH or NiCd batteries. Li-ion batteries are becoming less expensive and over time, we should see their price decrease significantly.
Are there travel restrictions for Lithium Ion batteries?
Yes. Passengers are allowed an unlimited number of spare batteries whose equivalent lithium content per battery is less than 8 gr. (Our 90Wh batteries). Each passenger can also carry no more than two lithium-ion batteries that contain more than 8 gr. of equivalent lithium content per battery, this includes our 120Wh and our 150Wh models. For more information, please contact your carrier for more information on changes in policy.
What is the best way to store Lithium-Ion batteries?
Lithium-ion batteries can hold a charge for many months. It is best to store a lithium-ion battery with a partial or full charge. Occasionally, a lithium-ion battery with a very low charge is stored for a long period of time (many months) and its voltage slowly drops to below the level at which time its built in safety mechanism allows it to be charged again. If the battery is going to be stored for several months, it's a good idea to take it out and recharge it after a few months. Better still would be to actually use the battery every few months and then leave it partially or fully charged.
How should I dispose of Lithium-Ion batteries?
Lithium-ion batteries, like all rechargeable batteries, are recyclable and should be recycled. They should never be incinerated as they may explode. Most retailers that sell rechargeable batteries will also accept them for recycling.
