Nah... a swollen Li-po or Li-HV battery is not dead at all, usually it have a lot of energy when fully charged and could give almost the same capacity of a not swollen one.
There is some risk to use it under strong discharge, this is, but how many times can be used again depends on many factors.
A small swelling is almost physiological, if it does not create mechanical difficulties, it can still be used many times.
It is always necessary to carefully check for its stabilty when inserted, that the connectors on the battery and drone are always perfect, that there are no traces of overheating and melting around the black rigid plastic resin insulators and it's better not to fly during high ambient temperatures, with the summer sun high, in sport mode, or under strong wind.
Wait untill every battery to well cool down, one or more hours before each recharge, this is very important to prolong the battery life and reduce the chances of swelling step by step (recharge after recharge).

I have a battery question.
Anyone experienced having a battery that charges normally, but when its installed into the bird and you take off, it immediately warns you that the battery is critically low and forces landing? The controller also reflects a 100% charge but the battery icon is in red.
Ideas?
(Dave never said swollen as a problem)
Charges normally? As in an hour for your 5 second flight? Or as in recharges in 5 minutes?
They make a charging plug for Mavic 2 batteries, hooks to battery and has 2 banana plug leads, if you I've a good lipo charger you can use to to load test it and check capacity
