LOL that dealer is scamming you or is just genuinely ignorant to high hell. absolutely should not get a used battery in return for a broken battery.. you should get a new battery. only exception should be while ordering a replacement battery they can toss you a known good used/refurbished pack, you can bring back when picking up your new pack. but trying to trick you into thinking its an acceptable replacement full stop, no. never.
first of all cannot define the 80% mark via cycle count or age..it is a measure of compacity at full. thats defined by usage. a battery that's got 80% life remaining means 20% of its total compacity is gone forever. also 80% isn't a magic number where anything could happen once more wear percentage, if properly maintained batteries should see same linearly loss in life throughout additional wear. secondly, age is a grey area because down chemistry.. and unlike what people think, not just lithium-ion vs lithium-polymer, each of those types have a huge list of chemistries, lithium-ion and polymer are umbrella terms, not specifically chemistry. dji's batteries are chemically doped for heavy cycling, dumping power and recharging and repeating, in fact most battery issues with dji drones comes from batteries being idle and them hurting themselves. finally, you mentioned bloating battery, that's no longer safe, that means a lot of off gassing and a lot of damage to the cells. a little bit of off gassing is normal, but if start bloating, times to replace that battery as it is damaging itself and could risk it dying mid flight or worse..catching fire..
but yes... you are completely in the right, if got a broken battery with a brand new aircraft from dji, you are entitled to a brand new battery replacement, no questions about it. |
