Compact, dry battery is firmly held. The price is also reasonable. I think that the spring on the minus side does not have to be strong so far.

Purchased that AAA battery operated equipment can be used with AA batteries. It is convenient with a power ON / OFF switch. AA batteries should last longer than AA.
Maintenance of equipment, as a dummy power supply for check
On 2017-02-03 17:04:06
Installed and used as a dummy power supply (standard power supply) at the tip side of a certain rotating equipment. Connect resistors in parallel at the root side, connect oscilloscope probes, use forced trigger to log whether there is no problem with rotary contacts. Previously I was using 3.7V lithium rechargeable battery (18650), but since there was no switch in the battery box, I introduced it here as a test. If there is no problem, I will replace them sequentially. The red-black lead pretends to be pretty shy.
