This is a pair of SEGWAY OEM Nickel Metal Hydride batteries for most GEN 1 Segways.  I bought them on eBay a few months ago for my XT, but found that the range was not sufficient for my needs and subsequently bought two Li-ion packs.  I no longer need these batteries.  These batteries accept and hold a charge with no problems.  Range is about two hours, using the BLACK KEY, less on the RED KEY, on my XT before they get down to the final bars of charge.  Therefore, they are in good, but not new condition.  Any other GEN 1 Segway will get significantly better range, as the XT has a lot more rolling resistance than any of the other models.If you need a set of backup batteries, please consider these.Shipping is FREE.
