Q: Why doesn’t Servaas Products sell rechargeable lithium AA batteries?
A: You can search high and low, but at this point in time, no-one makes Lithium Ion or Lithium Polymer rechargeable AA batteries as a matter of safety.
Lithium rechargeable cells are a completely different technology to NiCd or NiMH batteries. LiIon and LiPo batteries require controlled charging and discharging. Lithium battery cells are usually 3.0, 3.6 or 3.7 volts, which is quite different than the 1.2V cells that make up Nickel based batteries. If lithium cells are charged or discharged improperly, they can and do explode. The potential liability on the manufacturer of the batteries means no-one has been prepared to manufacture and sell rechargeable Lithium AA batteries.

Maha Announces a Battery Charger-Analyzer from the Future!
La Verne, California, USA – 7th November, 2006 — Maha Energy, the maker of Powerex batteries and chargers, is pleased to announce its most significant product in five years: MH-C9000 WizardOne Battery Charger & Analyzer. Suitable for the casual consumer users, enthusiast and professionals, WizardOne is capable of charging, conditioning, analyzing, cycling, forming and discharging one to four AA or AAA batteries, all while digitally displaying the battery capacity and voltage. All four slots can be operated independently in different modes and settings. A total of five modes are available.
Those seeing the unit for the first time will be struck by its large LCD screen, backlit by ultra-bright white LEDs. Measuring over 3.5†by 1.5â€, the display is more than three times larger than its closest competition and shows a wealth of information that is easy to read.
In addition to the standard charging, conditioning and discharging, the WizardOne charger-analyzer also offers two unusual operations modes. The “Break-In†mode allows the user to input the capacity of the battery and performs a “forming†charge designed to properly break-in new batteries. The “Cycle†mode allows user to charge and discharge batteries consecutively while storing the capacity for up to 15 cycles. There are ten selectable charging and discharging current from 0.2A to 2.0A and 0.1A to 1.0A respectively. The charger also features four independent temperature sensors using Maha’s latest temperature rise detection algorithm in addition to the usual peak temperature detection. It also armed with additional patented termination algorithms found in other Maha chargers.
The unit can be operated in a “basic†and “advanced†mode. In the basic mode, user merely needs to insert the batteries with no further key press. The charger will select the appropriate settings automatically, making it suitable for the casual users.
The WizardOne is also incredibly accurate. Using a quartz oscillator time base typically found in computer boards, it is able to report capacity within 1% accuracy across multiple units making battery bench marking more meaningful.
MH-C9000 is expected to be available in Australia from January 2007 with a price of $99.95. The standard package will include a worldwide travel power supply. A 12V car adapter will be available as an option.
