I don't know if it's a lithium battery but the battery is built in and rechargeable. Mine has worked great & I charge both the keyboard and iPad at night. I've been very pleased.

I believe the battery is for the keyboard. All I know is that I charge mine without taking anything out. Hope this helps.

There's definitely a builtin, rechargeable battery yes. That said, it doesn't seem to charge via USB - i.e. when I plug it into my laptop to copy files onto it, it can't get its power via the USB connection, nor will the battery charge if left plugged into the laptop for a long time. It seems like it'll charge only via the AC adapter.

the latest version of this calculator uses a single lithium rechargeable via a standard USB connector to charge it. however the owner manual for this calculator depicts 4, AAA batteries along with a CR2032 for backup. The newer model though only sports that one lithium. If the one you have or intend to have still uses the legacy battery system for this entire TI programmable line you should use AAA lithium's rather than alkaline. don't use ni-cad or ni-mh. finally, the single lithium rechargeable lasts a long time... AND the calculator even sports a battery monitor. Personally THIS is the battery system I'd be looking for and not the legacy type. the latest version of this calculator uses a single lithium rechargeable via a standard USB connector to charge it. however the owner manual for this calculator depicts 4, AAA batteries along with a CR2032 for backup.

There is a small "backup" watcg type battery but it is not a rechargable one. Although I am happy with this unit, I do not recommend it if you are wanting to use it without a power cord.

The new lithium ion batteries are really good. Get an extra battery. The cordless model is way handier. I also have a corded model, and I like the battery model best.

Thank you.Where can I get the "latest specifications from the manufacturer" that list lithium ion batteries as an "Option" ?

I recommend getting "eneloop" rechargeable batteries. They come pre-charged, and they can hold 85% of their charge for a year, which is great for emergency, as well as everyday use.

It does not come with a rechargable battery but I believe one can be added. I do not know anything about the other model.

This does NOT have rechargeable batteries, but this is actually a good thing. I find these speakers to be very powerful and having rechargeable batteries limits its potential if you are away from an outlet (like at the beach). Buying D batteries gives you the option to just have backup batteries if your current ones die. Rechargeable batteries dont give you that freedom.

We have rechargeable in ours. not sure if they're lithium, though. Good Luck! It is fantastic for focusing on paintings, photos, etc. R.

It comes with two rechargeable lithiums but only requires one at a time so u can charge one while using the other. If I remember correctly it also came with 2 regular AAA batteries so you have that option as well.

Thanks for writing Frederick. The SwingSmart comes with a rechargeable lithium polymer battery that is built into the module. Please refer to the following page for more information: http://www.swingsmart.com/index.php/support/faqs/#4

it has a rechargeable lithion -ion battery which cannot be replaced. I bought it because it does have a power cord which allows you to use it if battery is not charged.

There's PowerEx but there's been some problems with those even though many people probably are fine with them they are not really low Self Discharge batteries. I highly recommend the high capacity Eneloops but you could try the PowerEx's but i'd read the reviews first to see if you really want to get them.

You can either use a AA alkaline or a very standard lithium-ion 14500 battery and be able to recharge it without removal. It comes with a rechargeable lithium pre-installed. Great product.

Swifferbattery.com has a replacement rechargeable battery! Great and only option out there.
