4Pc Size D Panasonic Batteries Super Heavy Duty Power Zinc Carbon

Great batteries at a fair price. These work perfectly fine with my vintage looking flip clock

Great batteries if you're into namebrand. They arrived quickly and In good shape. I would definitely recommend these to anyone in need of batteries.

They do the job and they are cheaper than some other D batteries

YouTube says these last as long as the name brands.

I have a wall clock that replaced one that stopped working, The manufacturers technical support person advised me to switch to carbon zinc batteries from popular alkaline ones to avoid harm to mechanical parts of clock that play up to 30 different tunes. The face behind the hands also opens & spins on the hour. The clock runs for months and keeps precise time on a pair of these batteries.

Clock specifies use carbon zinc battery. For a very good reason, although the voltage is 1.5 v for all D batteries, the CURRENT PROFILE is not the same. These "inexpensive" clock motors made in China do NOT have a current regulator. Eventually, an alkaline battery will burn it out and have a short life. I expect around 3 to 5 months from this battery.

Thery work great! Super price!

These batteries worked fine for my smart faucet but only lasted about 6 months versus over a year for the batteries that came included with the faucet.
