my daughter will be using this on a 20 day backpacking trip. It says it has a 10 hour battery life. What are the options for batteries?

Hi,If your daughter will be using the watch every day for many hours, she would probably need some sort of solar USB charger, if there won't be access to other power.

The dock charges with a USB connection. A portable charger with USB port will work. When not hiking, turn the power off. http://www.amazon.com/gp/aw/d/B00OHZVN5U/ref=mp_s_a_1_11?qid=1432843549&sr;=8-11π=AC_SX110_SY165_FMwebp_QL70&keywords;=portable+charger

The battery is built in. This is not an ideal unit for backpacking trips, but more for running and cycling. For the same price, you can get a very nice Garmin GPS receiver that is intended for hiking in the backcountry.

If you use gps or cardio the batteries last less but they are quite good and 10 hours is a right number

I may not be the best test case for this but I can say it lasted me the entire week on vacation and had 20% of the battery life left after 7 days. I probably used it much less than the average user so I am sure your results will vary depending on usage. I would guess it would last at least the entire day under normal use.

Try Energizer Ultimate Lithium batteries ... I find they last the longest for the long haul. Don't do videos myself so cannot say that this will be an improvement; but it is worth a try.

It seems to hold a charge for several days, it's been 3 days sitting in my backpack now and it hasn't lost any charge. (Still showing 4/4 of its battery status lights) I'll keep an eye on this and get back with you towards the end if the week? If that's ok, and give you a better answer.

The battery life depends on how much you use it and how you treat it. I've had a similar one for 10 years and although I've only used it a couple times per year (more for camping power versus jumping cars), it still holds a charge and delivers well. I've followed the manuals recommendations of "recharge after each use and at least every other month" which I'm sure has helped with that. I saw a review of another unit where someone said "I charged it when I first got it, left it in the car for 10 months, then pulled it out to charge it and it wouldn't recharge". That's what you don't want to do, so always keep it charged if you expect it to deliver.

I'm not sure, I just use one of the rechargeable USB battery packs made for recharging cell phones - and they last for a longggg time. It lasted for nightly use on a camping trip for 4 days and still had power left with this one:http://www.amazon.com/gp/product/B00CTK762E/

bought for my daughter.i fully charged it 21 hrs and brought to her.she started doing her steps and after 4 steps she said get this thing out of here.i felt the same way.what a waste.im goen to try their 20 volt lithium ion for a little more money.it will stay at FULL POWER till it dies.and you don't have to play that 21 hr game to run it for 10 min max.lithium battery can be charged for 2 hrs or the max without hurting the memory at all.

1) no. 2) I have used a battery pack and it charges the camera's battery just fine 1-4 hours and during this downtime you cannot use the camera till it is finished charging. After my purchase I contacted the company and asked several questions also made a few recommendations as a customer that could make the camera more user friendly etc. No response! I am currently researching for another camera that will fit my needs and use this one as a backup or spare.

Sorry I've taken so long. We've been busy. On a trip to Machu Picchu, we took pics all day long and our battery held up well, only using about a half of it's life. I hope this helps. We bought a second battery so when we needed to, we could replace the other. I must say, I took 3 short videos in a row and the battery went way down. But just taking pics didn't seem to phase it much at all.

Adkins, thanks for the information. Gomadic's battery pack seems to be perfect form me. It is small, light and costs only $19.95. I'm going to order it.

I charge it before use for about 2 hours or you can charge it overnight. i dont know what the battery replacement would be.

I would say that 2 to 3 hours. You can buy the battery pack and go twice as much.

It usually last for 2 hours. You should be able to get a second Battery, even a bigger one.

Forget that battery and buy an 8 pack of AAA HD batteries from the Dollar Store for a buck. It will last about 2 weeks or more depending upon use.

The battery lasts for several hours of continuous use. I did buy a backup battery as well. It ends up being a race between running out of battery and running out of storage memory. I've set this up on a tripod and recorded continuously for at least 2-3 hours (possibly longer...I did a 5 hour recording but I can't recall if I changed batteries mid-way or not). I also highly recommend getting the water-resistant housing (clear/orange)..I've used it to dive to 80ft.+ and it's repeatedly worked great. That housing also serves as a tripod mounting point. Hope that helps...feel free to ask any other questions. The battery lasts for several hours of continuous use. I did buy a backup battery as well.

I bought this for my son a back in September and just use the supplied charger and only have the one battery. The battery last about 20 minutes. My son is only 7 so 20 minutes is a good amount of time and often times doesn't run it out as he gets distracted to other things at which point I have him just put it back on charge so it's always ready for him. Takes about 2.5-3 hours to fully charge depending how depleted it go. Hope this help you out!
