Battery chargers How we test
How we test battery chargers
In our test lab, we measure exactly how long it takes each charger to charge four batteries. We then run down each of the batteries in our computer-controlled test rig to see whether they have been charged to their full capacity.
We carry out this test with the batteries that the charger is supplied with, and then again with our own 2,600mAh high-capacity batteries. We also test the capacity our batteries achieve after being charged for just 15 minutes in each charger.
On top of this, we assess each charger for ease of use – including how easy it is to insert and remove batteries, noise, build quality and bulkiness of charger and ease of knowing when batteries are charged.
Our total battery charger test scores ignore price and are based on:
Charge achieved in 15 minutes - 30%
Charging supplied batteries - 25%
Charging generic (2,600mAh) batteries - 25%
Ease of use - 20%
