I got a new OSMO battery couple of days ago, it has only been charged twice since I bought it.   It became very difficult to pull out of the charger today.  It was extremely tight, very hard to push it in also.  It looks quite normal comparing to my other 2 older battery, so it must have just swollen a little.   Has anyone exprienced this?  Is there any warrenty on a swollen battery?

Lipo batteries that swell up are very dangerous. I would put it in a plastic bag and store it outside until you find a resolution to its dilemma.

Hello!
Sorry for the problem!
The Osmo's battery has a 6 months warranty if it has been used for less than 400 cycles, so, in your case, your battery is still in DJI's warranty, please contact the dealer for a replacement.
In addition, just as R&L Aerial said, you need to be very careful with the broken battery. Here, I'll advise you to read this thread for a better understanding about intelligent battery: http://forum.dji.com/thread-40320-1-1.html

I,m not sure of the electrical implications of leaving a battery permanently on charge, but LIPO batteries can catch fire very easily if overcharged or something goes wrong with the current management on the charger or battery.

I would recommend keeping all lipo batteries in a custom fireproof bag , or as I do, keep them in a steel box when not in use. It is worth researching "lipo battery fires" on youtube- scary stuff! hope this helps.

Hello!
Even thought that DJI's battery has the properties of over-charged and over-discharged self-protection, keeping a good habit of using and storage will contribute to prolong the lifetime of the batteries. When the battery is fully charged, please remember to cut off the power and remove it from the charger.It's always good to be cautious about the potential dangers in case of any accident.

The charger is terrible, remove the powercable and you will see the battery will keep feeding power BACK to the charger (light will continue). Remove these batteries from it when charging is done!

update:
I brought in the battery to the local DJI distributor in Hong Kong.  They concluded that the battery is not swollen and safe to use, the tightness might be caused by the battery housing being slightly out of spec.  They also said when I remove the battery from the charger,  I should pull from the connector end instead of the ribbon end.

I'm not keen on the battery charger and find my batteries quite difficult to get out. Is it better to pull them out by the connector end like Ray has been told? Last thing I want to do is damage anything.

Hi Adela,
Your video is suggesting not to pull out the battery from the connector, but your Hong Kong distributor (ECT) told me the opposite.  We couldn’t pull it out from the ribbon side.
I am confused now.

Hi,
Please follow my suggestion, as you may know, there is a small snap joint in the slot of the charger which will fix the ribbon side of battery, to avoid any damage, please push the battery to the other side slightly first and then pull it out gently.

Hi Adela,
this battery can not be pull from the ribbon side unless I use brute force.  it is extremely tight.  My other 2 batteries are very easy.   Does it qualify for exchange?

The battery of Osmo is within our 6 months warranty if it's been used for less than 400 cycles. You may contact your dealer or support@dji.com directly for an exchange.

No. doesn't work for me, even with 2 chargers, 3 batteries.

Here's my get a round:  Push the battery against the joint at the ribbon end. This forces the joint in a little helping you then lift the battery out. Cheap, nasty, contraction, that will get a redesign at some point.

Please be careful with the inner golden pins in the charger.
As for the issue of unplugging and redesign, I'll reported to our relevant Dept. to look into it.
Any good suggestions will be appreciated!

My original battery fits perfectly, but the two additional batteries I purchased are very tight in the charger.

The new batteries have a different label and appear to be made in Japan (have DJI Japan indicated on the label). I used a vernier caliber to check the dimensions on the batteries, and the 2 from Japan were a fraction of a mm wider on the corners (the main bodies are the correct width).

To solve the problem with mine, I gently scraped a little bit of plastic at each of the corners that fit into the charger (on the long sides). I only needed to scrape it about 1.5mm to 2mm from each end, from the bottom edge (with the label) up towards the join between the top and bottom sections.

Works a treat now and all the batteries are easy to insert and remove.

Thanks for your feedback about the battery.
We'll look into it and try to improve it in the future.
