4 Product Electric Performance Test
No. | Items | Test Conditions | Requirements |
1 | Capacity retention | Fully charging, store them at (20±5)℃ for 28 days, then discharge
to 11V @0.2C.(the residual capacity is above 85% of nominal capacity) | Discharging time4.25h |
2 | Cycle Life @25℃ | Discharge to 11V @0.2C, then Charge the battery @0.2C to reach
16.8V. Then charge the battery at constant 16.8V voltage until the
charging current decreasing to 0.02C. Rest for 10 min. discharge to
11V@ 0.2C and rest for 10 min. Continue the charge/discharge cycles until discharge capacity lower than 80% of rated capacity. | Cycles life ≥300 |
3 | storage | Charge the battery to 40%~65% of its rated capacity using standard
charging mode, then keep it in an 20℃±5℃, humidity 45% ～ 85% room
for 12 months, fully charge and discharge it @0.2C until voltage
down to 11V. (The testing sample should be within 3 months dated from production
date) | Discharge time≥4h |

Ryder Electronics established in Shenzhen on July 18, 2005, mainly
in the business of battery packs. In 2009 the company passed
ISO9001 and improved the product quality standard to fulfill the
high-end requirements from our customers.
In 2012, Ryder Electronics moved to a new facility and expend the
production capacity, the Productivity improved nearly 10 times than
before.
In 2013, Ryder Electronics imported ERP (SAP) system to supervise
order execution process.
In 2017, Ryder Electronics expanded the SMT, imported high-speed
patch machine from Germany.
Until now the factory grows into a modern enterprise which
integrated injection molding, PCB designing, SMT and battery pack
assembling services.
In 2018 the company passed ISO14001certification, introduced
automated battery production line to further improve the production
quality and capacity.
