Battery testing results from others

• Avoid zinc-chloride. Dollar store brands often better than major brands. These can leak.
• Alkalines generally better than zinc-chloride and generally don't leak per Bigclive.

1. From BigClive. https://www.youtube.com/watch?v=-I4liMndTsI. Batteries below from Poundland.
   • Kodak zinc chloride (just for reference) 0.85Ah
   • Duracell "Simple" 1.7Ah. One of the worst values per pack of batteries.
   • Kodak Extralife (Poundland) 2.0Ah
   • Duracell standard 2.2Ah
   • Powercell (Pound World) 2.3Ah
   • Fusiomax Endurance (Poundland) 2.65Ah
2. Battery Showdown. Tests 40+ models from UK. "There are low-drain results, for things like toys, torches, CD/MP3 players and similar devices, and high drain results for devices like digital cameras." http://www.batteryshowdown.com/
   • Duracell batteries tended to cost higher per maH. Ikea Alkalisk batteries were some of the lowest cost per maH.

Testing notes

1. maH can be different depending on load. Batteries can have higher maH with 0.1amp draw, vs 1.0amp draw. To simulate flashlight usage, use 0.03amp draw.
2. PRC68 battery testers. Great summary on state of charge (voltage) and capacity (maH).

Testing equipment

1. LaCrosse BC 9009 can both charge and test battery capacity for NiMH.
