"TD" wrote in message ... Where can one find rechargeable AA Lithium batteries? Any safe way to recharge those "non-rechargeable" Li AA batteries? It's just not worth burning the shop to the ground to save a couple bucks (in my opinion), just buy a name-brand rechargeable and be done with it. (¯`·._.· £ãrrÿ ·._.·´¯) |

Many devices designed to operate on a pair of AA cells can also use the RCR-3V Li+ cells (depending on the shape of the battery compartment).

A few manufacturers are shown he http://www.thomas-distributing.com/rcr-v3-index.htm Thanks, but I was really hoping for some rechargeable AA Lithium batteries to plug into my the battery compartment of my handheld GPS. My experience with disposable AA Li batteries is that they last a heck of alot longer than 2300 mAH NiMH AA`s. So I was hoping for something in this generic form. The key of course, is the compartment size issue. Tien |

My experience with disposable AA Li batteries is that they last a heck of alot longer than 2300 mAH NiMH AA`s. So I was hoping for something in this generic form. The key of course, is the compartment size issue. The problem is that the rechargeable Li ion chemistry results in a battery voltage of over 3V/cell and would probably damage your GPS receiver if you were to put two of those in instead of regular AAs, so AFAIK they aren't made in AA size. The RCR-3V cells get around that problem by making a single cell in a shape that approximates a pair of AA cells side-by-side and with a voltage of just over 3V which is also appropriate for two series AAs. They fit in the battery compartment of my GPS which was made for AA cells and may work in yours as well. The single-use AA lithiums are a different chemistry of Lithium Iron Disulfide with a voltage of about 1.6. Based on their specs they should last at least 50% longer than good NiMHs in a GPS receiver. |

You could buy a couple three sets of NiMH batteries, and a charger, before you could buy the lithium charger. #2 problem is that lithium batteries are 3 volts per cell, so you can't do a straight swap in an AA battery pack. -- Jim in NC --- Outgoing mail is certified Virus Free.

Even using a sophisticated charger, many Radio Control flyers remove their Lithium battery from the airplane and charge it in a remote location, away from other people, buildings, cars, etc. - just in case.

What makes this necessary for RC planes` Li batteries? I don`t recharge my digital camcorder or digital camera in the shed to avoid explosions! Or should I start doing that?! Tien |

Tien Many times the modeler is using faster charge rates than the low-amperage "wall-warts" which come with camcorders, etc. The risk of the battery swelling, leaking, heating or exploding increases along with the charging amperage. There is also the occasional case where someone uses a ni-cad charger for Lithium/Ion or Lithium/Poly cells, or misadjusts a multi-mode charger. There have been enough incidents now that most flying fields require that battery charging be done waaaay over there! Rich S. |
