1 Overall score
This is made up of:

  • Performance score: 50%
  • Value score: 50%

2 Performance score
We tested 10 samples of each battery using an international standard test that simulates the power used when taking a photo with a digital camera. We counted the number of photos each set of two sample batteries could take, and converted it to a score out of 100. While this is a good comparative test, in reality you’re unlikely to get that many photos from each battery set because other things, such as zooming and leaving the display on, also use up the battery power but aren’t taken into account in this test.
3 Value score
This is the cost for 10,000 shots (see Table note 7) converted to a score our of 100.
4 Number of shots per set of two
This is the average number of shots we counted that were taken in the standard test.
5 Sets of two per 10,000 shots
The number of sets of two batteries required to take 10,000 shots with a digital camera, based on our results.
6 Price (set of two/four)
This is the price for two non-rechargeables or four rechargeables, rounded to the nearest five cents. Some brands of non-rechargeable batteries only come in a packet of four, so the price is only indicative. We’ve listed the price for four rechargeable batteries so you can use one set while recharging the other.
7 Cost for 10,000 shots
For the non-rechargeables this is the number of sets of two batteries required to take 10,000 shots multiplied by the price for two batteries, as provided by the manufacturer.
For the rechargeables we based the cost on two sets of two batteries (so you can use one while the other is recharging) and a $50 charger. In fact you’re likely to get a lot more than 10,000 shots from rechargeable batteries as you can charge them several hundred times, so this figure is something of a bad-case scenario. Prices are rounded to the nearest $10.
