Product Name: Waterproof Battery Holder for 3 AA (Size 5) Batteries
(with Timer Function, Multi-Mode Control)
Appearance and Structural Features:
Overall Structure: This is a sturdy, durable black rectangular
battery holder designed specifically for holding three AA (Size 5)
batteries. Its most notable feature is its fully sealed waterproof
design, with strong snap locks around the edges to ensure the
battery compartment remains sealed in harsh environments.
Materials and Manufacturing:
Shell: The main body is made of high-strength engineering plastic
with a smooth surface. The picture shows two color options: the
classic black version and the transparent white version (the
transparent version makes it easy to check the battery level
inside).
Sealing Design: There is a sealing groove between the lid and the
base (usually used with a rubber gasket), combined with the locks
around the edges, effectively preventing moisture and dust from
entering.
Functional Design (Key Features):
Integrated Control Button: There is a round rubber button on the
top, which feels comfortable to press and helps with waterproofing.
Multi-Mode Control: The lid clearly displays English instructions
for 9 lighting modes, including:
Combination
In wave
Sequential
Slo glo
Chasing/Flash
Slow fade
Twinkle/Flash
Steady on
Off
Timer Function: Although the word "Timer" is not directly printed
on the surface, waterproof holders with complex mode control like
this usually have a built-in timer chip (such as a common 6-hour
auto-on/18-hour auto-off cycle), making them suitable for outdoor
decorative lights.
Dimensions:
Length: 79mm
Width: 67mm
Height: 22mm
Electrical Characteristics: The internal circuit is designed for
series connection, and three AA batteries can provide a DC output
voltage of 4.5V.
