Any 303 or 357 silver oxide battery will work. You can find these at battery outlets, box stores, and watch repair stores.

How do I put batteries in?

Yes the black cap comes off but a smooth knife edge
or cell phone "spud" tool might be needed to pry it
a little. Keep it coming straight off by not prying
too much on one side, then it just pulls off.
Batteries are held up in the black cap.

I had to pull everything out since it got flooded
and the rest of the guts came out by rappin it
with the opening down onto a counter.
There is a pad to make contact with the battery
and a tiny round piezo buzzer and then the end
of a very thin single sided circuit board slides out.
Once I got a bit of that out I was able to grab it
carefully with pliers and pull the rest out to
clean and dry it. Mine had two LR44 batteries.

I've had bad experience with cheap pill
batteries (short battery life) through eBay,
so you might do better to get name brand
LR44's for a much longer battery life.

How long do good name brand batteries
last in this thing?

Does a GB 504 A have a battery?

The 504A uses two silver oxide 357 button batteries. The black top is just press fit in. Gently pry it off. The batteries install with the positive side down.

Light blinks rapidly on both sides on some plugs and once on one side and multiple times on the other

There is no polarity-only active... Blinking means live wire. The further you get from active the slower it blinks....

Irregular function of tester GVD-504A

There are two button cell batteries located in the top of the unit. Try removing the black cap. Some twist off and some pull straight up. Note the polarity of the batteries.

I have 6 outlets that do not work.

I would start by determining if these 6 outlets are on the same circuit. Also I am usually not too confident in the non contact voltage tester you are using. They tend to give false positives if they contact anything or even if you move them fast. I would invest in an inexpensive multimeter whcih will allow you to test actual voltage across the poles and ground and also check for continuity between poles/ground (WITH CIRCUIT OFF ONLY).

Did these outlets previously work properly?
