Is the LI-ion battery user replaceable? The solar cells should operate many years longer than a rechargeable battery.

It is a false presumption that the solar cells should operate many years longer. "Some" types of solar cell construction, namely those put into long term use on building and large grids, are long life products. That does not translate into all solar cells having long life.

unfortunately, I don't see any area where you can take it apart to replace the internal batteries. I don't recall seeing how many charges they can have in their lifetime either. I have used it a few times while hiking already and it charges well even in indirect sunlight.

Rechargeable batteries are always replaceable. Some products make it hard to find replacement batteries and it is sometimes cheaper to buy a new product. It usually does not hurt to use a product when it is plugged in I do it all the time with my laptop.

With proper use (i.e. charging during the day and operating during the night), the batteries should last longer than 2 years. Like any rechargeable battery, over time the charge may not last as long as with say a mobile phone, but the lights are on periodically so I have not noticed any degradation over the 2.5 years I have had 4 of my lights installed. Finally, the bulbs are actually 60 LEDs which are attached to a circuit board and cannot or do not need to be changed. The operating life of the LEDs are about 20,000 hours far exceeding the life of the light.

regular batteries don't seem to last nearly as long, rechargeable batteries really do seem to last much longer.

My battery still works the same as new. Lithium Ion batteries like to be stored with at least 3/4 charge and normally have very long life. Avoiding deep discharge should also prolong life. There are several good battery encyclopedias on the web that will tell you all about lithium ion batteries.

Yes, they're all rechargeable, but a rechargeable battery loses a little bit of it's life each time it's charged, so after you've used a battery for a few hundred charges (2 years, maybe?) it will no longer hold a charge well. Some people can make them last forever!

The battery does not need to be replaced as it is easily recharged by the solar panel on the front of the light. The lithium-ion polymer battery is built to be long-lasting and is high-performing for 1000+ recharges.

They're internal lithium batteries like an iPhone. I don't believe it is replaceable but you should get a long life from these batteries

The rechargeable batteries are in the handle but they are not replaceable as far as I know. I bought one 6 years ago and the batteries still hold a charge for over an hour.

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...

You cannot change batteries on this unit without destroying it. If you're crafty you could charge your own rechargeable batteries with a solar panel, if that's what you're asking. Ultimately what you care about is how many mAh (milli amp hours) your batteries are rated for. This battery has a somewhat higher rating compared to smaller batteries, which is why it can charge two phones at once, or an iPad and a phone at once, but not two iPads. Higher mAh means longer life and will do a good job with iPads. Lower mAh values means longer charge time and shorter life. Some low end solar panels and batteries are ripoffs so spend more to get middle range stuff like this and avoid disappointment a month later. Like the battery. Don't like where the LED switch is cuz it accidentally gets turned on easily - not a big deal.

Energizer claims this battery holds its power 8 years if unused (see www.energizer.com/batteries/Specialty/watch-electronic/Pages/coin-lithium-1632bp.aspx). Because 8 years is promised, my guess as an Electronics Engineer is that the maximum useable shelf life may be closer to 9 or even 10 years.

I believe as long as you have good sunlight you can charge. I do not know how many years solar cells last but with a little care they should last for years......One mans opinion

You are absolutely right.With technology advancing so rapidly, you generally don't want to keep a device for more than a couple of years.Still, it would be nice to have the option of replacing the battery should you want to do so.

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.

Yes. Normally the battery can last about 2 years or more.The battery is inside the solar panel, need release the several screws.

yes the battery in our unit is still going after a year. it should last longer than that.
