So my GPD Win 1 battery started to bloat up. And the device restarts randomly.

Quite a journey though as I backed this up on IndieGogo and added with some back and forth with the GPD team of the first batch faultyness. GPD team took it like a champ.

Seems like I overcharged it very often and didn't use it for awhile because I get LDK and I game more on that (SNES and NeoGeo). I just play PSP games on GPD Win 1.

Anyway I know about Sunda, and I've discussed it around here quite alot, but importing them seems not quite an option for me, as Sunda batteries don't appear in Aliexpress. Importing them from europe, that'll cost a lot.

A quick search on Aliexpress gave these results.

HSABAT, seems popular. This is what the site show me with the keyword "GPD Win 1 Battery"

I'm very sure it have fake capacity. But I don't actually care as long as it works.

What do you think? Any of you tried either one of those? How do they perform?

If that is really bad I might take a shot at Ed's dragonbox shop.  That's around 100 euro include shipping to my country. Ouch.

Or any other alternative such as using other device batteries which will fit in size and deliver the 3.7 v to the win 1?

okay nevermind found this thread :

https://boards.dingoonity.org/gpd-windows-devices/gpd-win-1-battery-replacement/

also found the said battery on aliexpress. Dat shipping cost tho

They are on eBay a lot of the time, not cheap and in the EU so shipping might be too much. I bought a Sunda battery on eBay for 32 UK pounds which was reasonable. I also have one of the Liter ones which supposedly work well albeit with lower capacity, think the wires might need switching too but don't quote me on that. Haven't used the Liter one but it was pretty cheap compared to the official battery.

thanks

Liter and hsabat seem pretty bad

for hsabat there're lots of reviews on their other products on youtube

Alibaba now sells sunda batteries, but they're using different purchase procedure than aliexpress which geared towards retailer to consumer, compared to alibaba, which geared towards factory to retailers.

But chat with one of them, they will serve non bulk purchases, although at higher price, definitely.

Not sure the shipping cost though. I figure it would be the same, since battery shipping are a headache to deal with.

Only attempted to import battery once, and I lost the battery on the way here. Luckily it was only 5 bucks and the seller uses aliexpress's free shipping method (which I didn't have any problems before).

It's disappointing that there's isn't a reasonably priced reliable solution after all this time, although my unit is still working perfectly on its second battery (I bought the Win used originally too) I'm aware that one day it might be a paperweight if the supply of batteries dries up.

Are the new official batteries (non Sunda) that EvilDragon has meant to be any better in terms of longevity? Kind of got used to the battery in my XD lasting forever even after 4 years so it's a shame the Win isn't as reliable.

I haven't ordered any. Let alone this fucking covid thingy. Searching around further sunda batteries are your best (only) bet for sure. After the dust is settled I'll probably order two of them. That would cost me > $100

ED most likely imported them directly from the factory. And judging how such an idealist he is, I suppose his are fine.

I love my win 1. Didn't take the plunge on win 2 and most likely won't for win max. But this should be a good input for GPD, just use whatever available out there. They did that with the joysticks and buttons (PS Vita and NDS buttons I suppose?), why can't they do it with the batteries?

LDK uses microUSB and very common nokia BL-5c battery. On which are the main reason why I took the plunge.  I can find those everywhere easily though I'm skeptical they're legit nokia. But they works anyway. Yes it's far cheaper, far less powerful hardware, incomparable to even win 1. But using common parts would help the community a LOT, definitely. Samsung tablet batteries may be smaller but they are very common here. I'm pretty sure 3000-5000 mah should be enough.

Also seems that the problem occured on Win 2 as well. The batteries are frikin hard to find. Or do a replaceable batteries on the future products? Yeah those are outdated by today's standard. But judging by the cases found in Win devices, this is quite a headache.

The new batteries on Dragonbox are improved versions apparently and are made by a different manufacturer, no Sunda branding on them:

So they possibly might have more longevity, probably worth speaking to ED about it.

Yeah I just notice that

shipping from china is about the same with shipping from him.

I'd probably order from ED instead.

anyway when I search around for this thread some say it's not the battery, it's the Win 1 bad cooling that affects the battery, which is a last minute afterthoughts; the second speaker replaced with a fan before release. The bottom shell do feel hot when I use it, I might also go fetch myself a heat insulator material or some sort.

Btw you can get slightly better Nokia style batteries, I had them for the RS97 and the PAP K3P (they're sold now) and also currently have one in my RS90, the Playgo/PocketGo2 has Xiaomi batteries. Both the RS90 and Playgo have tool free battery doors which is brilliant.

I already had 4 of these batteries. I think one of them is legit nokia (all black), which last a lot longer than the others which have hologram stickers on it. The black one was the most expensive one I bought. But 2-3 hours with LDK is enough for me anyway.

I've seen a few 6000mah 3.8v batteries for Doogee and Homtom phones but it's anyone's guess if that is the genuine capacity and the connector is a ribbon cable so you'd have to butcher a board to hook it up.

was thinking about these batteries for win :

https://www.aliexpress.com/item/32842585151.html

no need to open up the batteries (which is I assume pretty dangerous), just reconnect the wires with GPD's connector.

But it's 4cm longer and a bit wider if I recall. Longer, you can pretty much remove the fan. It's pretty bad fan placement anyway. Wider, not an option.

Yeah I don't think the fan does much apart from make noise! I mainly use my Win for indies and old games so I have it set to prioritise battery life and it doesn't get hot really, if I want to play Fallout 3 etc I'll sacrifice graphics using BethINI or something.

Do batteries need to be 3.8v?

I don't understand electricity thingy; volts, watts and such. So IDK.

But I suppose they should have the same output as win's original so that all the components inside get the appropriate amount of juice as intended?

Anyway this is why I posted this thread in the first place. Will the rewiring affects the battery performance or the output? I mean as I see sunda have 3 (positive, negative and ground?) and those samsung batteries have 5. It is said that the two extra cables are to equalize the output?
