    Comments about PowerNow Standard 40V MAX 1.25 Ah Lithium-Ion Battery:

    Oregon offers 3 battery sizes for their outdoor power tools. The smallest (this 1.25amp) has a short runtime but it is a full pound lighter than the other two (the 2.4amp and 4.0amp). Unless you have physical weight limitations don't waste your money on this l.25amp battery. It powers my weedeater (the ST275) just barely long enough to mow my small lawn. It charges fast though...less than an hour on the standard charger. Buy the 4amp model. It costs more but will be cheaper in the long run, and you won't find yourself frustrated, waiting for the battery to charge so you can finish your job. You would need two of these 1.25amp batteries on hand to get most any job done.
