Hey guys, Here is a helpfull guide I found on Ion batteries. It may help those of you that just throw them in the Bag. It does make a difference.
Lithium-ion battery packs are a videographer’s dream. Extended run times mean fewer battery changes and Lithium-ion batteries are lightweight so shooters aren’t overly burdened, even if they carry a spare. But these features come at a price. Lithium-ion batteries have their own shortcomings and operating requirements. Here’s how to treat them right:
Avoid heat. Storage anywhere where the temps get above 120 degrees is very bad. Direct sunlight, closed cars, and tropical climates are all hostile environments that can lead to battery failure.
Treat them gently. Lithium-ion batteries are more likely to suffer life-threatening injuries from accidental drops and rough-handling than their predecessors. Cushion them with cardboard or foam during storage and transport. And try really hard not to drop them.
Be partial to partial-discharge. Lithium-ion batteries are not susceptible to memory-effect and will be helped, not harmed, by frequent recharging after partial use. Fully discharging a Lithium-ion battery on a regular basis will shorten its life.
Don’t store them fully-charged. Batteries that will not be used for 30 days or longer should be stored at a charge level of 40%-50%. Storing fully-charged Lithium-ion packs for extended periods will shorten their useful life.
Use them or lose them. Unlike their Ni-cad and NiMH cousins, Lithium-ion packs have a useful life of two to three years from the date of manufacture, whether or not they are used. Don’t buy spares. Order replacements when they are needed. Check the manufacturing date stamped on the pack when you receive them to be sure you are getting fresh stock.
Hope this helps. It was usefull for me.
