I'd like to have this on hand in case of an emergency. Will it store well? Will the batteries accept a charge if they've been sitting for a few years?

I have not installed it yet. It was a Christmas present for myself for a 1976 Airstream that I am restoring from frame up. My plans are to make this a completely off grid machine for emergencies as well. The kit did not include a battery charger (converter) so I need to purchase that. My research has led me to the decision of purchasing AGM batteries. You can put these batteries in an enclosed area and not worry about gas fumes, acid erosion. The gel batteries should hold a charge longer and I would highly recommend them to you. Speaking from experience if you have older acid batteries that have been sitting for a few years you probably will not get a charge. And if you had them sitting on a concrete floor they are finished. I hope this has helped. I am impressed with the kit from what I have seen and Go Power has a web site you can go to and watch videos for install.

Don't really know what to tell you for sure. It is kind of a guessing game as what will work best for you. I am happy with my purchase, my battery was so weak that I had to stay hooked to electric (only had about 20 minutes on old battery) this one works just like a new one should. I don't think any of the batteries will do exactly what they say. (seems just like a guideline to me)

I replaced my primary battery and so haven't needed to use it for a couple years now.I have been storing it mostly upright, but also on its side from time to time with no apparent problems.

I always kept mine fully charge and in my purse for backup. The batteries will be fine, I used mine for a year like this until I got a new phone. The batteries are still in great condition. The true worry comes from leaving them on the charger to long it cause the battery to get hot and expand which makes them go bad much faster.

Store at at least 1/2 charge. Lithium batteries do not store well when depleted.

Thanks! It's good to know, just for an emergency. I've run my Nextgen unit for about 5 years using 2 of their 2/3 batteries. I keep one in the unit and every month or so swap them.

I used to work for a battery company. If you keep them charged you should get 3-5 years out of them. Store them in your basement or somewhere cool. Do not freeze them ever

I get long life with fully charged NiMh rechargeable AA batteries. But, NiMh batteries lose at lot of their charge when sitting idle for a few weeks, so I carry a set of lithium batteries as a "backup". The lithium batteries can stay "fresh" for ten years or so, ideal for an "emergency" set of batteries. I know a lot of folks who only take 200 or 300 photos per year. That sort of person could get a year (or MORE) of use from one set of lithium batteries on the Fujifilm S700, without the "hassle" of carrying a charger on their trips.

I haven't had Wasabi's long enough to know about them in particular... Just generically, a decent lithium cell should be good for a few hundred cycles or 3-4 years... generally lasting longer if stored about 50% charged and at cool (40-70F) temperatures. Storing them completely discharged (or allowing them to completely self-discharge) isn't a good idea. These things are somewhat unpredictable -- ask Boeing -- but most of us hope to get a few years out of them...

I had varied life from all types of li-ion batteries both oem and alternate suppliers. The only factors I've found that some devices drain the batteries in the off mode and if the battery goes dead it will have little power after it charges if it charges at all. It appears to me that it's flip of a coin how long the usable life batteries have. As long as the battery does not leak or over heat I think for the price the Wasabi batteries are worth a try. I would not leave any of these batteries charge unattended.

Thank you for your inquiry. This item contains an internal memory that will store your information, even if the batteries die. If you need further assistance, please let me know. Thank you.

It would be fine to store this in a cold car, as long as you keep it fully charged. It may self-discharge a little faster in cold weather, so check the charge once a week. Inside it is an Advanced Glass Mat (AGM) lead-acid battery, like an Optima battery.

I disassembled an old unit that failed to charge after a year or so and removed the batteries. They would not charge with a "hobby" charger designed for electric RC cars and such. I then discovered that storing the unit in the charger when it is plugged in was overcharging the batteries. I have another unit about 4-5 years old that is still going strong. I charge the batteries overnight when they will no longer last a full brushing cycle. NiCad and NiMH batteries have a very limited life when charged to 100% capacity repeatedly.

The shelf life (time it can sit without being charged) is 6 months. If the battery will not be installed in an alarm system or UPS battery back-up (or any other device that trickle charges), then it should be top charged every 6 months to avoid permanent damage to the batteries. If it is installed in a security system or battery backup, these devices automatically keep the battery charged so it does not need to be maintained. The batteries we ship are fresh date codes and fresh from the manufacturer. Best Regards,Battery Supersite

I received my battery last March (2012) and fully charged it up to use mainly for an emergency or when I travel. I had really forgotten about it until you asked this question. I just took it out of the drawer and found that it is still charged up to 99%. This surprised me as it has been just sitting there for 11 months now.

Yes and the charge seems to last for quite awhile, a week or two in mostly standby.You can also get a replacement battery on Amazon. Keep it charged for emergencies.

It contains a sealed liquid battery; while it should not be a problem to lay it on its side for a short time, it's probably better for the long term to keep it upright. If you're using this in a rack, you may want to find a rack-mount solution.
