Review: Battery not new - The battery only charges to 80%. Not a new battery as advertised.
Review: battery doesn't charge - bought this battery and it came with a full charge. after the charge was depleted, the bluetooth speaker indicates its being charged, but it does not hold a charge. i'm about 60 days outside of the purchase window, so i can't return and i may not even be eligible for a replacement...just a $25 loss. Very disappointed!
