Review: Good battery, was hard to find the exact replacement for what I needed. - The polarity was wrong on the plug leads, but I knew that before I ordered it. The battery itself works great. Just had to cut the leads and swap the -/+
Review: a HIGH QUALITY LITHIUM ION BATTERY - The voltage is within specification, the battery holds a charge that meets specification, the battery discharges and recharges properly.
