The control set of Rayovac single-use alkaline AA cells displayed four bars throughout the entire 74:59.
#RAYOVAC LIGHTWEIGHT DD BATTERY SPY FULL#
The criterion was the number of bars in the battery display of the MZR-37 MD recorder after the 74:59 test was complete, with four bars indicating nominally full and a flashing display indicating battery recharge or replacement. The test consisted of making a stereo recording of 74 minutes, 59 seconds with a microphone and earbuds attached and marking seven to eight tracks while recording. I did not test NiCad cells because I wanted to test the products generally available from Rayovac. The first was a set of Renewal rechargeable alkalines in service for more than a year, probably closer to two an almost new (one use) set of Renewal rechargeable alkalines, the NiMH rechargeables, and as a control, a set of Rayovac single use alkalines.
That question led to a somewhat unscientific test at the 2002 Indy Racing League season finale at Texas Motor Speedway.ĭuring a lull in action, I tested four sets of AA batteries made by Rayovac. The question here was whether the NiMH batteries would work as well for me as the rechargeable alkalines. Because I spend a lot of time in a car, I thought the new charger could solve problems and give me no excuse for missing a recording because of dead or low batteries. It also works on 12-volt power, which need three hours in the car for a full charge.

The Rayovac PS4 works on AC and in that mode, four new NiMH AA batteries will come to full charge in an hour. Recharging the NiMH batteries wouldn’t be a problem, because the MZR-37 has charging circuitry and the PS1 charger, which I carry in my field kit, will charge NiMH batteries, rechargeable alkalines and nickel-cadmium (NiCad) cells. The batteries used in this new charger, called the PS4, weren’t the rechargeable alkalines, but were rechargeable nickel-metal hydride, or NiMH.
Its press release contained a boilerplate item about a one-hour battery charger for AA batteries.

I’ve used the batteries and the portable PS1 charger for years and also have a PS3 charger in the office that can charge eight AA batteries at a time or four C or D cells.Īt the 2002 Indianapolis 500, Rayovac sponsored driver Alex Barron in Indy Racing League competition. Rechargeable alkaline batteries come fully charged and you can put them in a machine right out of the blister pack. When I quit using a cassette deck to get field sound in 1998, I began using Rayovac rechargeable alkaline AA batteries for my MiniDisc recorders, the Sony MZR-37s. Rayovac’s line of rechargeable batteries makes that practice economical. That can get expensive if you change out four disposable (single-use) batteries at a time. The fear of losing an interview to dead batteries causes some of us to change batteries in our recorders before every major use. Radio field reporters and producers can tell you many stories about the “one that got away” simply because of batteries going dead in the middle of an interview recording session.
