Sometimes a deal goes sour after the protection of PayPal and eBay has expired.
Nothing to be done about it.
I have experienced a high failure rate among Chinese Li-Ion batteries.
In part due to Li-Ion batteries being a relatively new technology,
and in part due to manufacturers who do not invest in research and development,
and who have not developed adequate quality assurance procedures.
I still buy Chinese Li-Ion batteries, and have had the best results from UltraFire batteries
with built-in electronic controls to limit charging and discharge voltages.
For what they are, these high-performance batteries are absurdly cheap,
so it's no big deal to get the occasional dud.
