Picref-5: Smbus Level-3 Battery Charger/Selector Reference Design Based on the PIC16C73a - Microchip Application Note Published 11-May-98 (app note added 2/06)

Power Supply 5v Solar - This project uses the 1.2v rechargeable battery and solar panel from a Solar Garden Light. These lights can be bought for less than $5.00 in most $2.00 shops or similar shops that sell general household items diagram….(circuit added 05/07)

Powered AA NiMH & NiCd Battery Charger - The charger in this project is designed to charge two AA NiMH or NiCd cells of any capacity (as long as they are the same) at about 470mA. It will charge 700mAh NiCds in about 1.5 hours, 1500mAh NiMHs …. [Stefan Vorketter]

Pre-Charged (Low Self-Discharge) Rechargeable Battery Roundup - It's been about two years since I first published my review of Sanyo's Eneloop low self-discharge rechargeable batteries. Since that time, other manufacturers have jumped on the bandwagon…. [Stefan Vorketter]

Rechargeable CMOS Battery - Occasionally we come across a computer motherboard that seems to eat those CR2032 batteries every 4 to 5 months. This is particularly frustrating because the computer works perfectly once booted but all the important BIOS settings are lost when the CR2032 battery fails. This is very irritating if the affected computer will not boot up with the default BIOS settings. I recently had a computer motherboard with this same irritating phenomenon. A test revealed that the current drain... [Radio Amateur Society of Norwich By N1HFX]

Rechargeable flashlight obsoletes lantern battery - 11-Dec-03 Issue of EDN This Design Idea describes a high-intensity, rechargeable flashlight system that you can build from a 6V lantern-type flashlight. The rechargeable battery comprises four 2V, 2.5-Ahr (ampere-hour] SLA (sealed lead-acid] cells, similar in size to a standard D-sized battery. SLA cells are especially well-suited to powering flashlights because of their low self-discharge rate.... [Design Idea by Fran Huffart, Linear Technology, Milpitas, CA]

Salt Water Battery - (electronic circuit added 10/05)

Scheme provides automatic power off for batteries - 13-May-04 Issue of EDN The circuit in Figure 1 provides a simple and inexpensive way to protect one of the most valuable components in portable applications the battery. Applications include all portable equipment that requires a limited time of operation, such as test instruments, guitar tuners, and electronic toys. Pressing the on/off momentary switch starts the cycle, and the circuit provides power to the applic.... [Design Idea by Miguel Gimenez, Altair-Equipos Europeos Electronicos, Madrid, Spain]
