Gave this for a Father's Day gift, We charged it all day and it will not hold the charge at all.  Only works if plugged in so not much use in the shower.  I see other people have the same complaint.  Very sad.

BATTERY WILL NOT HOLD A CHARGE - There are many complaints online about this product not holding a charge after a very short period of time. This is the case with mine and I am unable to do a warranty return because it is impossible to contact the manufacturer. DO NOT BUY THIS PRODUCT!!!!!

This battery will not hold a charge.  I seem to be charging my phone every 2 days.  I use my phone for emergencies only.  I hardly use it but I like to know it's available if I would need it.  It wasn't expensive so I won't return it.  I just expect to be able to have a good product, no matter how much it costs.

I cannot even charge this unit!  The charge light stays red after 6 hours of charging.  If I cannot get this to work in the next 6 hours, I am returning.

this battery would not stay in the computer, will not hold a charge, and unfortunately we disposed of all packaging so have not returned it.

It is worthless!

Does NOT hold a charge.  After only 2 months, the speaker started to reduce the amount of time it ran on battery and now does not operate unless plugged in. The speaker has not been wet, dropped, or in anyway abused.  I should have read non-amazon reviews as this appears to be a frequent issue with this model.

Worked great at first, then wouldnt hold a charge.  Waste of money.

Quit holding a charge after a month or two. I would leave it plugged in overnight to charge, and I'd get less than five minutes of play the next day.

Recently ordered this and the battery would not hold a charge.  Requested a replacement, which also did not work, so I the requested a refund.
