Requires a 4.35v charger to get 3000mAh. 4.2 charger you will get 2500mAh. 99.9% of chargers out there are 4.20v chargers.

Thanks for alerting me!
A review did mention about 4.35V charger o/p but i do not know you will not get full charge because of that. Thanks Pal.

HJK says that it works but it’s very spartan. I bought one the other day, I’ll see how it works for some of my Acer Aspire –28A’s.

It’s kind of tempting because with the blf code it’s $18 per four cells. But I looked it up, naturally HKJ has tested these cells and under high drains the capacity is less stable than the –28A. Comparing the charts, under a 3.0A draw, the –28A and –30A both give about 2600mAh.

Thanks for the findings. Guess it is safer to stick to 4.2V.

The dash28A is still a 4.3v cell. Tallboybass said he has the charger I linked/bought and though it’s 4.35v charger, the light changes colors at the 4.28v mark +/- 0.3v, according to him (supposedly there’s still terminal 4.35v indication).
