GP Ultra AAA Review: High capacity

Decent overall chapters shows that the GP Ultra AAA could be suitable for less enervating tasks, but fluctuating results in my loftier-bleed tests results in a low average capacity for more than demanding jobs. Cost-wise, they’re decent, just other batteries performed better in my tests.

Introduction

The GP Ultra AA batteries are some of the best I’ve tested, then I had high hopes for the GP Ultra AAA’s performance. Overall, total chapters in my tests was practiced, just the initial high-bleed test didn’t evangelize the results I’d hoped for.

These batteries are available in a wide range of pack sizes and compete well on price against both the large names and budget brands. To test these batteries, I bought a pack from Amazon and then ran them through my battery tester.

Performance

• High-drain examination was a fiddling disappointing
• Overall capacity is first-class

GP quotes the operation of the Ultra AAA as a service life of xviii.v hours, based on a twenty-ohm discharge resistance, quoting a starting voltage of one.6V down to an end-point of 0.9V. These figures are quoted within xxx days of manufacture, so with a shelf-life of ten years, await some variation in packs that you purchase.

I measured the starting voltage of the batteries that I bought at ane.52V, which is higher up the 1.5V threshold that I’d expect for alkali metal batteries.

To test capacity, I used an Ansmann Energy Ninety-3000 tester, which runs a battery drain at 600mA (+/- 20%), ending at a voltage of 0.94V. This is a relatively high drain. After the initial test, I found the batteries had an initial chapters of just 364mAh – that’s virtually 200mAh less than the Amazon Basics Element of group i AAA.

Looking at the results, there was a great bargain of fluctuation in each of the batteries tested, with the highest returning a capacity of 523mAh and the everyman 243mAh.

I then left the batteries for a few hours to cool downwards, thereafter re-running the examination to see if there was whatsoever current remaining. Hither, I recorded the GP Ultra AAA with 234mAh, giving a total chapters of 598mAh. That’due south actually the highest total chapters of whatever of the AAA batteries I’ve tested.

My results would suggest that these batteries are better for low-drain devices, such as remote controls, rather than higher-drain usage in such items as a torch.

Latest deals

You tin purchase the GP Ultra AAA in pack sizes of betwixt iv batteries (effectually 88p per battery) up to a 40-pack (effectually 35p per battery). I’ve listed the twenty-pack hither (around 45p per battery), since it’s a good balance betwixt the total number of batteries and price.
