Product description
Battery tester with LCD-display. For quick and easy testing of hearing aid batteries (zinc-air batteries). When cleaning or using the hearing aid, the battery is sometimes removed, making it easy to forget or confuse which batteries are still working. The battery tester has a key ring and a battery compartment for two batteries.
Keep in mind that a zinc-air battery that has just been activated (protective tab removed) takes a while to reach its full voltage. Wait 5-10 minutes before testing a newly opened battery.
- Dimensions: 10x30x50 mm.
- Suitable for battery types: 10 Yellow, 13 Orange, 312 Brown, 675 Blue
