PowerGenix ZR-PGX1HRAA-4B 1 Hour Quick Charger with 4 AA 1.6v NiZn Rechargeable Batteries Reviews

But it does not fully recharge to 100% within one hour. If you read the fine prints, it actually says "For maximum capacity from batteries charge up to 2.5 hours".Despite its misleading name, this is actually a decent 'smart' charger. It works from universal input voltage (100-240V), and accepts 1-4 AA cells or 1-2 AAA cells. Each cell is charged individually (not in pairs). The red LED lights up during charging, and the green LED lights up when done. Just remember that you must not use this NiZn charger for NiMH cells, and vice versa. The batteries are the new Nickel-Zinc rechargeable AA cells. The greatest selling feature of... Read more 49 of 52 people found the following review helpful  Are these things really better? Or are they going to destroy your gear?, Amazon Verified Purchase This review is from: PowerGenix ZR-PGX1HRAA-4B 1 Hour Quick Charger with 4 AA 1.6v NiZn Rechargeable Batteries (Electronics) Interesting technology....and somewhat scary if you look at the 1.8 volt figure. I got a 2 set of them to test. I have UW LED lights..and two large strobes that both take 4 AA batteries.Until trying these, I have been using eneloop's (or the japanese duracell version)..which are very nice nimh's. The larger capacity standard rechargables work well in the strobes for the first 20 or 30 cycles, but eventually one of them will have charging/discharge issues and mess up the strobe firing and recycle time. As they are higher voltage, there is the possibility that they would not work, or could damage equipment, so I started my testing with a simple 4 AA LED light that produces around 100 lumins. I charged the batteries and put them in light, and tested the light for one hour every week. The light was slightly brighter initially, but to my amazement, did not loss very much brightness over a two month test window (standard Ninh's drop off considerably after the two...

I'm impressed by how long they will power things compared to the usual NiMh cells.I have a Magellan GPS unit that uses 2 AA's. It was probably designed for alkaline cells. New alkaline cells give a full scale battery bargraph, but freshly charged NiMh cells only make the bargraph hit about 80%. NiMh cells drop to about half scale after an hour. I only get about 4 hours with NiMh cells before the voltage drops too low and it turns itself off. Alkalines will last about 7 hours. The new PowerGenix NiZn cells give a full scale battery bargraph for about 3-1/2 hours, then it slowly drops until the unit turns off. My first test powered the GPS for 6 hours and 20 minutes, the second time it went 6 hours and 55 minutes. I left the batteries in the charger longer the second time I charged them, about 4 hours instead of 2. With my GPS, the PowerGenix AA's lasted almost twice as long as 2200mAh NiMh. I... Read more |
