Panasonic Pro Power AA



Official specifications (I could not find any real specifications):

• Up to 80% longer lasting
• Panasonic’s Pro Power battery offers premium energy for your personal appliances.
• Developed to provide reliable and dependable power, any place any time.
• The improved capacity of the new Panasonic Pro Power battery has up to 80% extra performance compared to last years Alkaline ranges.
• Premium alkaline range: developed to provide reliable and dependable power, any place any time.
• Ideal for high and medium drain appliances.

Somebody pointed me to a datasheet (Not on Panasonic website):

• Name: LR6 / M / AA / AM3 / MIGNON / MN1500 / 15A / 15AC
• Made in: Belgium
• Type: Alkaline Foil
• Nominal Voltage: 1,5 Volt
• Electrolyte: Potassium Hydroxide
• Average weight: 23,3 g
• Storage temperature range: +10°C ~ + 25°C
• Operating temperature range: -20°C ~ + 45°C
• Average Impedance: +/- 105 m-Ohm @ 1kHz fresh
• Heavy metals: No added mercury (Hg), Cadmium (Cd) or Lead (Pb)
• Compliant to: IEC 60086 non dangerous goods regulation, Nordic ecolabeling (white Swan), EU directive 2006/66/EC
• Recommended cut off voltage: 0,8V per cell

As can be seen on the numbers and on all the curves: alkaline batteries does not handle a high load very well.



















Conclusion

According to specifications, these batteries are much better than anything Panasonic has sold before, but looking at the curves they are not very impressive for flashlight usage.
Being the first alkalines I test, I cannot say how well they compare to other brands.
