Battery charging issues

Andrew Mac · Feb 15, 2020

Aloha,
I purchased a replacement battery from Yuneec for my Typhoon H, $230.00 delivered to Hawaii, ouch! Anyway, the new battery is a Power 4P. I thought this is the direct replacement for the standard battery supplied with the unit new? The new battery will not take a charge in the factory charger. Anyone have this issue?

Power 4P is the original battery normally unless it is a copy.
Have you tested the battery voltage?
If the voltage is at or near 0, it may no longer take charge.

The battery is brand new, arrived from Yuneec yesterday. When I place it into the charger the green ready to charge just keeps flashing. Like the bettery is not recognized in the charger. The charger functions normal with stock battery.

What does it say on controller? Are you getting a reading, not much else you can do unless you have another charger and leads.. I didn't suggest a multimeter, just in case you aren't confident in using or even have one.

@claudius62 asked the primary question. We understand the battery is new. That tells us nothing about the actual voltage.
Please check the battery voltage and tell us what it is.
If you don't have an external battery meter, the voltage can be read on the ST16 screen in the upper left.

Avez-vous vérifié la tension de la batterie?

Won't be new, can be a few years old!

Yes, thank you. the voltage is now 14.2 volts.
I placed it into the drone and took it out and hovered for a few minutes. I get the low voltage warning as normal. but the charger will not sense the battery when I place it into the charger. Just the flashing green light stating ready to charge.

How long are you leaving it in? Could it be going through it's preparation to charge sequence, balance checking etc, I only used stock charger once a long time ago.

Has now been sitting in the charger for +10 minutes.

Now getting a blue intermittent light and a beep tone!

Use a pencil eraser to clean the 3 small contacts on the battery. Then try it again. You may have to reinstall the battery several time before it makes good contact.

Cleaned with contact cleaner. No Joy!

What about wiggling the battery to reseat it, the DY3 charger can be very temperamental like this as an example.

Andrew Mac · Feb 15, 2020

Amen! How well I know, but yes I have wiggled the crap out of it with no change.

The battery flap lid/catch what's the date of assembly/ manufacture? If you don't have any other means to charge it, then it might be worth returning.

Looks like 09/05/2018, I sent a email to Yuneec, will wait until Monday for a reply. I don't mind a return and replacement. although the shipping cost to Hawaii (hazmat) is $50.00.

Andrew Mac · Feb 15, 2020

I'd prefer aftermarket through Amazon, but they will not ship the batteries here.

They should pay hopefully it's faulty. Interesting date, all my new batteries 2018 onwards have been poorer performers than 2016/17 ones, possibly cheaper components, inferior?
