What type of batteries does it require? And what's the battery life like compared to the keychain BACtrack?

Two AAA batteries power the BACtrack S35, and because of this, it lasts about twice as long as the keychain in terms of uses.

I'm sorry that I don't know much about it. I had to return it, as it wasn't compatible with my iPad4, only works on iPads up to that version. It is a keyboard, that you charge. No batteries needed, and I understand that it holds a charge for quite awhile. It was a nice quality keyboard.

I go a month on a charge. I use the keyboard every day and leave in "On" continuously, whether I'm using my iPad or not. I'm very pleased with the keyboard's battery life. I previously had a keyboard that used 4 AA batteries. I was forever running out of power, and at inopportune times like during a meeting or at a conference. I don't even think about the battery with this keybord.

This pointer uses a single AAA battery, but has room for a spare battery inside the pointer's body, which useful. However, I stopped using it altogether due to its low reliability: it works only sometimes. Also, it has too many features, which actually get in the way when you try to keep your mind on the presentation and not on operating the pointer. Ronny

I believe that the battery is a Lithium ion. It is entirely contained within the Keyboard and is rechargeable.. According to the manufacturer the keyboard should operate for up to 3 months for up to 2 hours a day

It uses a button battery, I have owned it for almost a year and use it all the time without major issue. It uses the ultra lower power consumption bluetooth transceiver so I wouldn't worry about battery life. It is not rechargeable though, you have to buy a new one when it dies.

I dont know. Love it. However I do not recommend keeping on your keychain. Its very sensitive

It is a small plastic container with 2 compartments that I put 2 batteries each. It has a short chain you can loop into your key chain. I just put it into a front seat compartment instead of carrying it around.

Anker's description states "700-hour continuous-use battery life and automatic sleep mode allow up to half a year between battery changes (requires 2 AAA batteries, not included)." Keyboards and mice have pretty low power consumption, so that sounds about right.

I am not sure what kind of battery is in there. It is built into the case and is fully rechargeable. I have not even had to charge it yet because it has held is original charge for two weeks. This is a great case and the best blue tooth keyboard I've used, outside of Apple's BT keyboard that is made for computers, but can be used with an iPad. I hope this helps.

The battery IS replaceable on this unit. Simply remove the 4 screws from the base of the unit. The base won't remove, but you can turn it clockwise to show the battery pack. The battery pack is essentially 6 AA rechargeable batteries packed together. The previous TDK boomboxes required 12 D size batteries, so don't expect good battery performance. Also, when using the battery power, make sure the power button located BEHIND the unit is in the ON position.

Once charged, I used the key board about 3-4 hours daily for one and a half week, and still with battery!!! But this depends on the use!!

There are two types of batteries. In the main unit are little batteries smaller than AAA's. In the individual units the batteries are the round type of batteries about the size of a dime. I don't know the cost yet since the unit came with extras. BTW, this works so great, I use it for the TV remote, my wallet, my cell phone etc. Note the sticky things that come with it don't work so well when kicking around in a purse, but I found some double side carpet stickies that work great, as you do not want to use glue.

The Perixx Periboard 710Plus uses (2)AAA batteries and has no charging options. I don't use this keyboard anymore because there are several problems with it. One is that the battery cover kept falling off, and was almost lost a couple of times- this is a design problem. The second problem is the touch-pad is much too sensitive and was constantly causing unwanted actions. The third problem is that the keys are too small to do and serious typing on. The fourth problem is that the range very limited- I was having problems using it when sitting 10 feet away and had line-of-sight to it's receiver. The seller said it must be due to interference from other devices using radio frequencies for operation like cordless phones or Wi-Fi, but this was not the case. It sits on a shelf now, unused. I replaced it with a Logitech KR400R keyboard which although larger, it's much easier to type on and the touch-pad mouse works perfectly and has the right amount of sensitivity. It uses 2 AA batteries and goes into low power mode when it is idle so battery live is very very good. I liked it so much I bought 4 more- I highly recommend you consider it and avoid the frustration of buying the Perixx keyboard. Good luck.

keyboard battery is included and embedded - nothing required on your part. Use a USB cord to charge it once a month with moderate use. Works like a champ!

it has an internal battery - it comes with the cord which you connect the keyboard to a standard household outlet. basically the same as charging a cell phone. in fact, many cell phone cables will work with it also. i've plugged mine into the same car charger cord i use for my cell to enable charging while i drive. so far, i've found that the battery holds power for much longer than i'd expected before needing to be recharged. hope this makes a little bit of sense - i'm not much of an electronic whiz so my wording is not very "techy" : (
