Hi all,

I've never seen such degradation before, but the Celxpert battery inside my C930 has lost 1/3 of its capacity in about 2.5 years of light use (perhaps that's the reason, but that's how I use my laptops, mainly for travel). I tried all the discharge completely and recharge stuff, but the capacity has settled at 41Whr out of as-designed 60Whr. There are many replacement options out there and I am not inclined to get the original part. Any suggestions on what would be a good option that won't crap out the same way?

Thank you!
 
I have had some good luck and bad luck with aftermarket laptop batteries. It's a toss-up really. It's also not something that I researched in-depth at the time.

I had one aftermarket battery that I had to modify slightly to fit.

If you have the budget, I'd go with O.E.M.
 
I too have had mixed results with aftermarket batteries - but even the best didn't come close to the originals. So for me, going OEM is the better solution. Plus, and this is certainly no guarantee of anything, but I "felt" more comfortable going with OEM replacements. With all the horror stories about shoddy aftermarket Li-Ion batteries, I like to think the notebook makers have more incentive (happy customers = returning customers) to ensure the OEM batteries are of better quality.

Oddly, I am the complete opposite with replacement batteries for my UPSs. I never buy from the UPS maker. But then those are SLA (sealed lead-acid) batteries and not Li-Ion.
 
Ok, thanks. The budget for OEM is there, no problem. The prices are not even all that different, actually...
 
Then I guess you just need to decide if you will be keeping that laptop long enough to pay for the difference.

Not sure what you mean, because the difference is like $20... I mean, yes, I do intend to keep the laptop, including out of curiosity to see if the replacement craps out the same way. :)

It sounds like you did understand what I meant.

If only $20 difference, it probably does not matter.

My last laptop was an 11 year old, 17" Toshiba, still running fine with the original battery. I say "fine", but the battery had aged and only provided about 50 minutes of runtime. Plus, while speedy in its day, it was still an 11 year old notebook with components from 11 years ago - including a hard drive.

A factory original replacement battery was nearly $200. I could find 3rd party replacements for around $75 - but I still was not sure I wanted to invest $75 in an 11 year old, old and slow (by today's standards) notebook, knowing any of the other aging components could fail at any time. After all, 11 years of reliable service was already stretching my luck.

In the end, I decided to buy a new laptop with modern specs instead of throwing money into that old Toshiba. And I'm glad I did.
 
Well, that Yoga C930 is actually quite new and it is an excellent laptop overall, plus the OEM battery is something like $80. The old battery in fact gives me about 4.5 hrs, so no rush, really.
Overall, I'm no longer inclined to buy laptops with hot-running CPUs and large batteries, because my use is under-utilizing everything. Just ordered a very curious Chuwi laptop for my gf. It's supposed to be very light, runs Celeron N5100 and promises 7-8 hrs with something like a 35Whr battery.
