Technical info on Beillen Li-ion batteries
Advantages of rechargable Li-ion batteries
  • higher energy density means that Li-ion batteries can store more energy than same size or same weight counterparts;
  • lower self discharge rate means that Lithium-ion batteries retain their charge for a longer period of time, even for weeks or months of storage;
  • there is no memory effect, so Li-ion batteries are capable to hold the same charge even if they are repeatedly recharged after being only partially discharged;
Proper handling of Li-ion betteries
  • storage temperature is important, store in a cool (below 25°C or 77°F) place to prevent capacity loss;
  • it's suggested to fully charge and discharge the battery after stored for more than 5 months, then charge for 40% once more for longtime storage;
  • in general, Li-ion batteries provide 300-500 discharge/charge cycles. Try to avoid frequent full discharges, partial discharges result in longer battery life.
Safety precautions 

Lithium-ion batteries might be very dangerous when mistreated, so safety rules must strictly be observed.
  • Operating temperature should be below 45°C or 113°F.
  • Do not put the battery into fire or into water
  • Do not expose the battery to direct heat
  • Do not short-circuit the battery pack terminals
  • Do not force to open the battery pack
  • Do not drop the battery, avoid fierce strike
  • Do not expose the battery to direct sunlight for a long period in an enclosed place, for example in a car

Notes: data valid at 13.0 V constant current discharge.
Maximal power consumption of your camera can be found in the operation manual. Eg. SONY DSR-570WS: 26.1W; DSR-390: 22.1W (with viewfinder). Source: Google.com
