## Questions & Answers

**Q: How many watts (AC) does this draw when charging?**
A: I don't have a B662 battery, but I do have a pair of B650E Oregon batteries (a bit under 2 years old) which appear identical to the B662.  They are 6.0Ah 40-Volt lithium-ion batteries and are cosmetically identical to the B662.  I used an Oregon C750 rapid lithium-ion battery charger, which has specs shown on the device of an AC input of 120V & 260W and a DC output of 41V and 4.0A, or approximately 164W.

I connected a B650E battery to the C750 charger.  The battery was approximately 3/4 charged before I placed it into the charger.  After a few seconds the AC power consumption of the charger stabilized at 208 watts.  I did not have a fully discharged battery available (and unfortunately no way to quickly discharge the battery I was using), so I don't know if a fully discharged battery will cause a larger AC power draw with the C750 charger.

**Q: Will this battery power my first generation saw model # 547462 & will the charger from my older saw charge this battery? asin b005h3nfji??**
A: Hello, Roger. Thank you for your interest in the Oregon® brand.

All of our cordless tool batteries will work in all of our tools. This 6.0Ah battery will fit, work in your CS250 and will fit and can be charged in your older battery charger.

You can reach them between the hours of 6:30 a.m. and 4:00 p.m. PST at 1-800-223-5168, option 1. You can also email them at oregon.support@oregontool.com.

**Q: With the oregon 16” cs-300 saw, does the oil reservoir support the full run-time for the 4.6 amp battery?   how much oil is left?**
A: This battery holds enough power to make up to 400 cuts in 2–3 in. media on a single charge.  How much oil is left in the reservoir will vary based on the application.

**Q: My Oregon 4 and 6 amp hour batteries stop delivering power when there is still one charge light showing.  Why?**
A: You should call Oregon customer service for help on this issue.
