Since some customers report that their notebook internal charger not function. A stand alone smart battery charger have been developed by our engineer, currently compatible with ~30%-50% of smart battery in the world. Will upgrade the firmware to make more battery compatible.
- SBS(smart battery specification) version 1.0/2.0(with PEC transfer protocol) compatible.
- Up to 3A charging current. Charge to 80% within 2 hours and fully charged a 4400mAH in~3.5Hours for most notebook battery.
- Using SMPS, High charging efficiency >80%. (Generate very less heat during fast charging)
- Maximum 200mV stepping voltage.
- Constant current, constant voltage charging (current loop inside a voltage loop) algorithm.
- About size of a normal notebook power adapter. (Direct connect to battery)
- If anyone interested can give some comments.
No compatible with:
- Dell with ExpressCharge(TM of Dell) system.
- Fujitsu and some Toshiba no SBS comply.
- Compaq special battery with built in charger. (E.g. ARMADA(TM of Compaq) series)
- Old Asus or Old IBM with one-wire(TM of Dallas) protocol.
Will add support upon request. In future, we plan to make a smaller one so that it is more portable.
