Vado 4 Battery Charger :

[BarryS]

Is The Charger they sell on Specialized's Website for $200.00 any Faster charger then What they supply with the Bike : They told me with 2 bars it would take about 3 Hours : I don't think it took 1/2 that time : Just curious if it's worth it to get a Faster Charger . Is one even available ?

The problem with much faster charging would be cooling the battery. I don’t believe they make any other charger or battery made for faster charging.

Neither did I > But The LBS lead me to believe the Charger being sold was an upgrade : I've had my battery down to 2 bars left : It took less then 2 hours to charge To where the green light on the charger came on :

It is the 4 Amp charger (I own two of them). The charging time from 5 to 100% is 4.5 hours for the 604 Wh battery. It would be 3 hr 45 mins for the 500 Wh battery. Does it answer your question, Barry? What is the rated current of your charger? 2 or 4 A?

I have a 2A and 4A charger. Figure 2.1 minutes per unit of measure (Ah?) for the 4A and 4.2-4.3 minutes per for the 2A.

per unit of measure (Ah?)

It's Watt-hour (Wh). According to your information, my 504 Wh battery would charge from 5 to 100% for (1-0.05) * 604 / 2.1 = 273 minutes or 4 hours 33 minutes and that's right.

It’s all voodoo.

@Marcela, I have got a Specialized table specifying charge times for different chargers and batteries. I can post it if anyone is interested. Your estimates are correct!

No I don’t. A little math is all. And the timer on the iPhone.
