No batteries required. Generally, ordinary daylight is quite sufficient. In the nighttime an ordinary electric lamp is enough. It's a great little calculator for a very reasonable price.

I can't use this calculator at night. The lamp light doesn't provide enough to the solar cell for the display to be visible

No, the cable does not charge the batteries. If you want rechargability, then you will have to use rechargeable batteries and a separate battery charger. In addition, any USB cable that has the proper ends will work, it doesn't have to be one specifically manufactured for use with a TI calculator.

One twelve vote battery. Make sure to charge the battery after using. It will take time to work. The battery may need an additional charge. Normal driving should then keep it working good. Make sure there are no bad cells in the battery.

I'm very sorry but I can not answer that, I wasn't kidding when I said my 12 yr. old grandson did the work for me.Seems to me you should be able to run a charger and get enough life into the battery to maybe jump start the darn thing though? but I'm guessing.Dennis

I am told it worked fine, I sent it to my nephews. I do know that it does not need to be charged it should work the moment it is plugged in. BUT the whole thing is one circuit. If one piece is not properly connected the whole thing will stop. Make sure each piece of track is connected properly and and everything is correctly plugged in. The only issue I was told of is that the 5 year old got a little frustrated the first time as the cars came off on each turn. When the 4 year old tried rather than pulling the trigger all the way down he pushed it down less, which makes the cars slower so it stays on the track. Once they realized they needed to slow down in the turns they fell in love with it. I am told it worked fine, I sent it to my nephews.

When I ordered this product, it contained instructions for how to properly charge the battery for the first time. If I recall correctly, they recommended a full charge to 100% before use, and then unplugging the laptop and letting the battery drain all the way to 0%. Beyond that I don't remember any other tips. However here's a website that provides additional suggestions. The main point is NOT to keep your battery running at 100% AND plugged in at all times.https://www.luculentsystems.com/techblog/how-to-extend-laptops-battery-life-span/

Hey what's goin in man! I got this car a few months back and it's a great starter car! Pretty fast! I would get some exta battery's! Just get the same one it comes with! If he seem to take an interest in it then you can spend some more cash to get some good ones! One thing you need to know when you first get the car the first time you charge the battery charge it for 8 hours straight even if the charger says it's done! If you don't the battery will only likes 5-8 mins good luck brother

Are you sure you have working batteries in it? I'd check that first.You also have to stand on it a few seconds before the numbers appear.It initially should be set by standing on it until it starts toregister the weight and, then, get off it and wait for it to displayO. You can then weigh yourself. If you move the scale at all, resetit. Also, it really needs to be on a flat hard surface. (Don't recallwhether the scale came with a tab that needed to be removed for thebatteries to work or not but, again, I'd check the batteries first.)Finally, the display is not baclit, so needs to be viewed in areasonably lighted area. Hope this helps. Are you sure you have working batteries in it?

I really don't know. From what I understand with any battery you should fully charge the battery before each use and you should fully let it die (don't keep it plugged in while you are using the computer at the same time). Not that many people actually fallow these suggested steps but they help to is that to elongate battery life.

Yes BUT --- know the battery MUST BE FULLY CHARGED FIRST --- best done with switch OFF. Clearly many have had problems coz of turning it on FIRST --- these batteries aren't meant to be fully discharged (can ruin them, actually). That said ... Out of 2 I own, one Has A Charging Problem with it... And calling customer service is really a bad idea at the moment. There Is GOOD REASON why this toy is selling out all over the place --- it IS a fantastic item, but it ALSO is Electronics, meaning it is Not Perfect, and IS prone to mechanical/electrical failure as are ALL SUCH SOPHISTICATED Devices ! Personally, I LOVE Robots, and have bought all 3 Models (Dalmation Black Spotted White, Female Dalmation Pink Spotted White, & Purple Body Male). I had to buy them all Online --- still waiting for the Purple one. So, I may be prejudiced, a bit. I'm a retired NASA Rocket Scientist almost 70 years old, too... Love good toys and this IS a Great One, just, sadly, mebbe a bit ahead of its time, in that THESE should be Proto-Types of more Evolved Versions, to follow ! We need a USER's Group !

It works with a AAA battery. There are some AAA batteries that are rechargeable, but it's not worth getting set up for that. A normal "over the counter" AAA will work for a very long time. Don't forget, there are no moving parts in this device, so power demand is ULTRA LOW on it. Yes, it does have an LCD screen on it, but its really small, so doesn't use a lot of energy there either. I have had this device for about 6 months, put a "Duracell" battery in it, and have not changed it yet. Oh... and it DOES have a "battery life" indicator on it, so you won't get caught "short".

You could use a Lith battery. When you get the unit test it immediately. The unit I received had a defective manual function.

mine didn't... it arrived without even batteries... had to buy them myself and then when i went to put them in, the calculator didn't even frigging work... what a waste... i suggest going elsewhere.

You know I have forgotten....It was a gift for a grandson Christmas PAST...:-)))))..so suggest you stock up on batteries...:-))))))

This item does not require batteries to work. The tester uses the charge in the battery being tested (if the tester doesn't light up, the battery is dead).

Yes.I put the spare battery I received with my purchase of the TI Nspire CAS in the calculator to charge it worked fine.
