Help Best place for replacement computer battery ?

Be careful, some of the batteries communicate with the laptop through onewire protocol, not an issue for using charger to charge any ole battery. I guess that central pin is easily damaged and shorts out, maybe some of the generic batteries would not take that 3rd wire into account.

I just finished up my Dell 7A 19.5C charger setup on my split back ebike battery. Just found a guy local who is selling them, there are higher amp chargers out there. This is your goto for any info on that

they do not sell batteries

But I am sure its easy to build your own.

Sorry I cant be of more help.
 
If I needed a laptop battery I'd look for one at Amazon because:
1. Lots of choices there.
2. They have reviews. The quality of their reviews is sure not as good as in the past but they have them at least.
3. You can buy a battery that's "Sold by <some seller> Fulfilled by Amazon." Then, if something isn't right after you get it, you can complain to Amazon's customer service.

Looks like Acer Aspire batteries are $30 max?
 
Look at the battery model number you'll almost certainly find a replacement on eBay or Aliexpress.
