Universal Battery Tester – BT168 – Volt Checker
For AA, AAA etc, 9V and Button batteries!
Don’t throw away perfectly good batteries!
That’s a waste of money, time and not good for the environment.
Many toys and appliances will stop working if even only one battery is flat, the other batteries might be fine, so no need to replace or throw those good ones away.
This unit is strong enough to last for ages, and we really like the analogue display as no need for a battery to use the unit! Classic proven design.
