User questions & answers

Question:	Lithium ion or lithium polymer
Answer:	These are Lithium ion. If you have any other questions please feel free to ask. Thanks JCKirk.
Question:	Are these low self-discharge
Answer:	yes
Question:	Are these truly 1.5v or are they 1.2v like all of the other rechargeable AA batteries
Answer:	Yes, they maintain a steady 1.5V. Others have done tear-downs on these, and it appears inside is a 3.7V Li-ion cell that has been brought down to 1.5V using miniaturized electronic circuitry. One caveat - these batteries will maintain a steady 1.5V until the very end of the discharge cycle, and then suddenly drop the voltage. Thus, keep a few spares handy.
Question:	Your first generation tenavolts state in title that they are "lithium/li-ion", so is this interchangeabl or is this lithium battery different? how so
Answer:	Exactly! The cathode/anode materials of TENAVOLTS are LiCoO2/Graphite, which are widely used in rechargeable battery. They would be interchangeable and reversible when charging and discharging.

Product description

Pale Blue is focused on creating a better future by leveraging technology, innovation, and inspired product creation to greatly improve our utilization of energy and resources and greatly reduce the amount of waste we all produce. Pale Blue rechargeable batteries have better voltage stability, current output, and stability than alkaline and old school NiMh rechargeable batteries. Our batteries charge in one fifth the time of a similar NiMh rechargeable! In America alone, 10 million batteries are thrown away every day. One pack of Pale Blue USB rechargable lithium batteries can replace up to 4,000 alkalines. Making the switch can save you money and keep toxic disposable batteries out of landfills. #DitchDisposables

• DITCH DISPOSABLES: Don't throw away cash with disposable batteries. A single Pale Blue rechargeable will replace 1000+ alkaline disposables! Every battery you buy needs to be produced, shipped, stored, sold and disposed of. We believe this is a huge waste of the world's resources and creates unnecessary waste and carbon footprint. By using one Pale Blue, you can displace the need for 1000 batteries. This will save a lot of resources, and will also save you a lot of money over time.
• A DIFFERENT KIND OF RECHARGEABLE BATTERY: With our advanced lithium rechargable technology, Pale Blue batteries charge 5x faster than conventional Ni-MH rechargeables. Most rechargeables historically were NiMh chemistry and recharge very slow and have a hard time keeping up with any high use applications. NiMh batteries will also discharge when not in use. Pale Blue's chemistry and smart circuitry resolves these issues.
• EASY CHARGING FOR ALL OF YOUR DEVICES: Power up quickly when you are on the go, at work, home or traveling. Charging times are surprisingly fast. That way you're always charged to power the devices and toys you love. Our on-board micro-USB charging port (4 end charging cable provided so you can charge 4 batteries at once), or just plug any micro USB cable to charge four batteries at once.
• BUILT-IN LED CHARGING INDICATOR: Pale Blue Batteries let you know when they are fully charged. Thanks to the advanced Lithium Ion technology, your batteries will last over one thousand charges. They charge fast and easy, so if you need to put them to work and suspect they are not full, just plug them in for a little while and you'll be good to go very soon.

User questions & answers

Question:	Can I use them to charge my cell phone directly
Answer:	The same length as a mop or broom handle.
Question:	is the 4 port splitter 2.0 or 3.0 usb
Answer:	Let it do it’s own thing, sometimes the bot seems to get confused but I let it do it’s thing for 6 runs , basically three days. Then the app told me mapping was done so there was the option of creating rooms. In that respect, the perimeter that you create on the floor plan may seem right on, but the perimeters seem to be off by a couple of feet (which isn’t an issue for me). When choosing specific rooms for bot to clean he goes to weird places for the first 5 minutes but then he’ll go where he’s supposed to. The bot has a sometimes erratic way of mapping, and eventually cleaning, a room. I spent a good 3-4 days following him around and found that in his own weird, erratic way, he gets the requested task done. Warning, he does not like furniture to move, I.e coffee table. I found that if it wasn’t in the same place where it originally was, then he won’t clean between sofa and table. Hope this answers your question
Question:	How do you recharge them if your p/c breaks down, have no car
Answer:	It will remap if you cancel the existing map and start over. I had to do that in one of my areas.
Question:	does the charging port come with the batteries
Answer:	This model does not mop.. Dont put fluid anywhere in this model.
