What is the IATA restrictions for traveling with Larger Lithium ion batteries?
According to IATA regulations, the Lithium ion batteries:
(1) Capacity under 100Wh: not restricted to carry-on or air cargo shipping; 
(2) Capacity between 100Wh-160Wh: Only 2pcs per person allowed to carry-on, and air cargo shipping is not allowed;
(3) Capacity over 160Wh: Neither carry-on nor air cargo shipping is allowed.
Please note that Check-in Luggage is not allowed for all kind of Lithium ion batteries. Also, please check your airline before you travel.

Why SWIT dividable batteries are not restricted by IATA?

SWIT developed the dividable batteries: S-8132A/S, S-8152A/S, S-8172A/S and S-8192A/S with over 100Wh capacity but can be divided into 2 parts before boarding, and each part has less than 100Wh capacity, which will comply with IATA and it’s a best solution for people who need high capacity but also want to travel by airplane.

When using the battery pack for the first time, what should I do?

(1) The lithium-ion battery has no memory effect. The battery pack can be recharged before being fully discharged. 
(2) To take advantage of the battery pack, it is recommended you charge and discharge the battery completely at initial use. 
(3) If you don’t use the battery for a long period of time, please charge and discharge the battery every 3 months. 
(4) The self-discharging of the lithium-ion battery can be neglected.

What's the compatibility of the SWIT battery pack and chargers with other original products?

(1) All SWIT V-mount batteries can be charged on SONY original charger BC-50/100. SWIT charger 302S/304S/3802S/3004S can charge SONY original batteryL40/L60/L80/75. 
(2) SWIT DV batteries and charger are compatible with the original charger and battery with the same mount. 
(3) SWIT Gold mount batteries and chargers are not compatible with any other brands.

What are the difference between SWIT High Load batteries and normal batteries?

The High Load batteries S-8260A/S, S-8210A/S adopt high load cells, which can load higher power than normal batteries. The normal Li-ion batteries can load max 100W/8A equipments in total, while the S-8260A/S can load max 180W/15A, and S-8210A/S can load max 150W/12A. The High Load batteries are suitable for Cine Cameras and high power camera lights.

How to calculate the running time of batteries?

Check the power consumption of the camera (or the equipments to be powered) and the capacity of your battery. For example, if the camera is 15W power consumption and your battery is 47Wh capacity, then the theoretical running time is 47Wh/15W=3.13 hours. Considering the power loss and the low power protection, the real running time is about half an hour less.

How long it will take to charge SWIT batteries?

Please download and check the SWIT battery charging time chart at:  (Sign in before download).  

How long does it take to charge and discharge the battery pack? 
The time of charging and discharging depends on the remaining capacity of the battery pack. 
1. Click here to check the charging time (Sign in before download). 
2. The time of discharging= capacity (WH)/actual load (W) 

Why does the LED indicator show full capacity but the battery pack cannot supply power? 
1. The remaining capacity is showed through calculating the voltage. After the battery used for a long time, the capacity will reduce accordingly. The voltage will become high when charged which makes the power look full. Actually, the capacity is very low and cannot be used for a long time.
2. For some model battery, there is a build-in intelligent circuit which has multiple protections of abnormal current. When the battery is used over its normal current, the over-current protection will be trigger. 

What's the compatibility of the SWIT battery pack and chargers with other original products? 
1. All the V-lock battery packs can be charged on SONY original charger BC-50/100. SWIT charger 302S/304S/3802S/3004S can charge SONY original battery L40/L60/L80/75. 
2. SWIT battery pack and charger can also compatible with other original charger and battery with the same mount. 
3. SWIT chargers can identify the different types of batteries. Ni-cd, Ni-MH and Li-ion battery all can be charged under secure and reliable conditions. 

What is the function of the connector at the front of the SWIT battery pack? 
It can connect SWIT wireless receiver mount S-7002 and also the SONY original microphone C1/C2 can be attached to the mount. 

Why do some batteries lose capacity after only about one year of usage? 
The life cycle of the Li-ion battery is normally charging and discharging 500 times. If used in high frequency, the cell will age more quickly. 

What is the difference between LED light S-2000 and S-2010? 

S-2000 is D-tap plug designed, input DC is 10V~17V. S-2010 is for DV camera with the bracket adaptor S-7200F/P/J/C, or powered directly by SWIT battery S-8972 and S-8D62, input DC is 6V~9V. 

Why you introduce Chip Array LED as the “New Generation LED Light” ?

LED has taken the place of Halogen bulb light several years ago, for its higher light output, lower power requirements and longer life. However, the only disadvantage of LED is too sharp, shinning and glaring, comparing to the traditional Halogen bulb.
SWIT introduced the Chip Array LED technology, which integrates the LEDs into a chip, only one bulb in appearance, and produces bright but soft, glareless light.That’s the “Halogen bulb feeling LED technology”, the best choice for news gathering, interview, etc.

For SWIT S-8845 / S-8972 / S-8BG6 / S-8D62 / S-8823 batteries, what is the pole output jack size? 

The inner diameter (core diameter) is 2.1mm, the outer diameter is 5.5mm. DC connector: 2.1mmx5.5mm power socket. 






For some SWIT batteries, is there a way to read how many cycles the battery has gone through already? 

For S-8172/S-8160 batteries, the method to roughly read cycles is as follows: 

Press and hold the power indicator button for about 5 seconds. The power indicator light will start to flash. The flashing times stands for the cycles. For example, if the cycles is 53, the tens digit will flash for 5 times, and the unit digit will flash 3 times. 


The following picture shows the detailed info to make this more clearly. 




Why do some SWIT products use the "Walkart " logo? 

We use the "Walkart" logo for all of our batteries and chargers in the US market, we use "SWIT" logo for our other products, such as monitors, LED lights, etc.
