Carga de baterías Hero 9 [ Edited ]

[tole123]

Buenas, tengo una consulta sobre la hero 9. Tengo la cámara con 2 baterías y con el cargador doble oficial pero la cargue por donde la cargue, bien desde la propia cámara como desde el cargador, una vez que los led me indican que ya está cargada, siempre la carga máxima se me queda al 95%. Os ocurre lo mismo u os sube al 100%???

hi,

here is almost the same.

battery fresh charged in dual charger put in camera shows 95%.

still I saw 100% sometimes.

is strange.

I would give the battery the chance to charge / recharge couple of times 

I use a 2A wall charger but as well I used GoPro 3A charger and USB-C power bank so maybe counts.

just me,

robert

Thank you very much, I will try a powerbank and a 3A power supply.

as I said, I saw 100% as well....

a 3A over 2A chargers only reduces the charging time.

a quality cable could make a difference not to lose voltage on it and the battery not be at max.

with wall charger 2A in the dual charger 

• the one in the camera - fresh charged with shows 100%
• the one in the charger with green LED - put in the camera shows 99%
• the one that now is orange LED showed 95% - but after fully charged, stayed one night in the unplugged dual charger.

I'm sorry I did not mark the battery to know which came with the camera, with the dual charger, and the spare one...

a little too much to test, I might think of a discharge current when left in the unplugged  dual charger

but as long as are close to 100%, with quite new batteries, I'm good.

if in time will not gain all 100%, I would make some tests.

pfff...

two of the batteries left overnight in the dual charger (green LED) show both 96% in the morning

I think you will find that most battery chrgers will charge to max and then stop charging as a measure top reduce damage to batteries. this cycles for the period you leave it conected, the actual chare % will be within the top 5% of charge. Hence on the charger it shows 100%, but shows 95+% on the camera

[robert1326]

I think the same.

Also found this post in the battery forum:

https://community.gopro.com/t5/Mounts-Accessories/HERO9-Black-Dual-Battery-Charger/m-p/735191#/M1538...

still...

I charge two batteries in the dual charger.

green LED's.

put in the camera shows 97% respectively 98%

if now I charge in the camera the LED is red, meaning charging.

when red LED is off, the battery is 99%

so it is more like a hit and miss.

as

• I do not feel the camera becoming hot when charging
• on the dual charger just a slight increase in temperature
• and the new design with the battery half free

I just hope is a normal controlled process designed to prolong the battery life.

just me,

robert

@tole123 @jollyjap 

mystery solved with the charging!

if I use an USB-C to USB-C cable and a 3A capable power source (Anker Powerbank), the batteries charge both in the camera in dual-charger at 100%

thank you,

robert
