Data: Brand / model Uniross Hybrio Price N/A Alternative packagings — Origin China Store Vali Date of manufacture N/A Condition (age) Tested items are brand new Low self-discharge (LSD) Yes Discharge (1-hour rest) 5.06 V 1460 ±1% mAh (≅1.85 W·h)     Discharge (5-day rest) 5.02 V 1340 ±1% mAh (≅1.68 W·h) ~9% self-discharge     Discharge (1-month rest) 4.98 V 1240 ±1% mAh (≅1.55 W·h) ~15% self-discharge Date of measurement Jun 2013

Notes:

This is a test of the LSD-type cells from Uniross (Hybrio brand). Cells are courtesy of surfer from HardwareBG. The packaging states a quite humble capacity of 1600 mAh, and some description of what their Hybrio technology does, which is just another name for LSD. And while I have no complaints in the capacity department, the 1-month 15% self-discharge rate is definitely not small. Indeed, the capacity at the month test, around 1240 mAh, is no less than 75% lower than their best LSD counterparts.

The cells have an otherwise good balance, less than 100 mAh difference.
