How do you change the battery, and what kind does it take? Husband got one for Christmas, and the battery won't hold a charge.

Never had a problem. Haven't charged mine in four months still has charge. I would try another charger power source to eliminate the charger from consideration.

It is a USB charge only. We haven't had much luck getting ours to work properly.

I have the same the problem. It may common cause of battery. Got a new one last year. It works fine until now but I don't know for how long. Nothing you can do to make it works since it no longer hold charged.

I asked my husband and he suggested you take it to Walmart and try it on the battery they have there. We purchased one from Walmart and one from Amazon once he realized how nice it is to not have to change batteries every couple of weeks. Hope that helps.

I've had this unit since November 2013 and have not had good luck with the battery holding a charge. I have contacted Waterpik and hopefully they have a solution. I will follow up here when they respond.

Do not leave it plugged in! I did and my battery is now dead. It turns out to be VERY expensive to change the battery b/c you must send it back to the manufacturer to do so. There are some good tips here on preserving the battery life that I really wish I had known beforehand. I'm currently trying to decide if it is worthwhile to replace the battery or not.http://1866uselady.com/show.php/en/online_store_2

It is simple to replace the battery. You have to unscrew the battery cover, take the old battery out, replace the battery with the same type battery and then replace the battery cover.

That is the only way to change battery is to get the screws out. I haven't had to change mine yet, but you need to get the cover off. Try to make sure you have the right screwdriver to fit so you don't strip the screws.

I believe you can change the battery. If it's difficult for you, maybe a friend or family member can help? I have not had to replace my battery, but if I remember correctly, you just use a small Phillips screwdriver, take the back off, & replace the battery with a new CR2032 3V battery.

Try charging the battery before buying a new battery. Mine needed replacing because the charge wouldn't last for more than 15min.

I have had this computer for approximately 14 months and my battery holds charge now for only about an hour to 90 minutes. I am having difficulty finding another one, can someone please tell me what replacement battery would work? thanks!

Take out the battery and reinsert. If it still won't work use a fresh recharged one. If it still doesn't work you need to call them and probably need to have it repaired.

My apologies for the delay. I have never had to change the batteries so I have no idea how to help you. I will contact the manufacturer for details. Thank you.

There are some guides online to tell you how to replace the battery. It involved de-soldering and soldering, so really only do-able for advanced DIYers. I tried and failed (but learned a lot about soldering on the way, so the $15 I invested was not completely wasted). Of course doing so will also void any warranty, so it's really only something that you will want to attempt if you have nothing to lose.

I know that the company has the batteries because they sent me a new one when I complained that mine would not hold a charge. My suggestion is to call the company at the number listed in the manual which is 1-800-798-7398. If you have had yours less than one year, they may send a new one free. Good luck.
