Unique-Bargains 2pcs AA Battery Holder Case ON/OFF Switch 15cm leads Black

Two-slot AA holder with switch

This pair of black plastic cases holds two AA cells side by side and includes a built-in on/off switch. Each unit ships with 15 cm wire leads ready for soldering or quick connectors. The compact 6.8 x 3.3 x 1.8 cm footprint suits small enclosures such as RC vehicles, drones or hobby electronics. Two holders are supplied in the pack.

5 W and 2 A continuous limit

The supplier specifies that the holder must not exceed 5 W or 2 A while operating. This single electrical ceiling determines whether the part can drive your load without overheating the contacts or melting the plastic. Check your circuit’s steady-state draw against these figures before committing to the design.

Steady-state thermal behaviour

Under sustained load the plastic body and metal contacts will warm according to the current passing through them. The supplier notes that battery heat generation should be monitored and that poor-quality cells must be avoided. Staying below the 5 W and 2 A limits keeps temperature rise within the holder’s intended operating envelope.
