The 1.2V AA 3000 mAh VTEC Ultra Capacity 2 NiMH batteries are being distributed by LRP and NOSRAM, popular names in the remote control models and are supposed to be of high quality and true to specs. So if these guys say that the batteries from their VTEC brand are supposed to offer a given capacity you are expecting them not only to meet it, but also exceed it. Now, these VTEC batteries are being sold as 3000 mAh capacity (clearly written on LRP and NOSRAM websites), though on the batteries themselves only 3000 is written and not a single rating mentioning capacity in mAh. Anyway, let us see if these batteries are able to offer the performance they are supposed to or not…
Starting our test of the 1.2V AA 3000 mAh VTEC Ultra Capacity 2 NiMH batteries as we normally do with a low constant current discharge rate of 0.2A and the result we got was just 2178 mAh as capacity. As we’ve already mentioned the VTEC brand by LRP/NOSRAM is supposed to be offering high quality products that do not come at a very affordable prices, so we repeated the test multiple times with different batteries, but the result was pretty much the same. And we are sure these are not some fake Chinese batteries branded as VTEC as we got them form an official distributor of NOSRAM. Getting less than 800 mAh capacity at lower discharge rate than the supposed capacity is a real disappointment, we really expected a much better result. Even if we take into account that the higher the capacity of NiMH batteries goes the faster they self-discharge in the first day after being fully charged, loosing so much in terms of capacity is just a few hours is way too much to be considered an option. And while the performance remains good when increasing the constant current discharge rate at up to 2.0A in our tests, these batteries clearly should’ve been labeled as 2200 mAh and not as 3000 mAh. Again, these VTEC batteries have shown us really unsatisfactory performance and have disappointed us quite a lot, so there is no way we would recommend them as there are much better alternatives.
The performance of the 1.2V AA 3000 mAh VTEC Ultra Capacity 2 NiMH Batteries in our tests:
– 2178 mAh at 0.2A load
– 1967 mAh at 0.5A load
– 1839 mAh at 1.0A load
– 1805 mAh at 2.0A load
– 2.729 Wh at 0.2A load
– 2.407 Wh at 0.5A load
– 2.179 Wh at 1.0A load
– 1.938 Wh at 2.0A load
1.5V AA Xcell Alkaline Battery Tests
6, Oct 2013
The 1.5V AA Xcell Alkaline batteries don’t seem as something special, but we’ve decided to give them a try and see how good will they be able to perform in our tests. The batteries we’ve used for testing were with an expiration date of just the year 2017, no specific month, so they should be with either 4 or 5 years of shelf life.
Starting our test of the 1.5V AA Xcell Alkaline batteries as we usually do with a low constant current discharge rate of 0.1A we have managed to get 2063 mAh as capacity. With that capacity they do not manage to get into our top 10 of best AA-size Alkaline batteries, though the level of capacity they offer is still more than decent if the price is right. Increasing the level of constant current load that we are testing with to 0.2A we still get a decent useable capacity, but past that the performance gets even worse, so better not use these batteries for higher power drain applications.
The performance of the 1.5V AA Xcell Alkaline batteries in our tests:
– 2063 mAh at 0.1A load
– 1586 mAh at 0.2A load
– 761 mAh at 0.5A load
– 267 mAh at 1.0A load
– 2.521 Wh at 0.1A load
– 1.858 Wh at 0.2A load
– 0.859 Wh at 0.5A load
– 0.293 Wh at 1.0A load
We have already tested more than 10 various 1.5V AA-size primary batteries (single use non-rechargeable models) from various brands including some of the most popular such as Duracell, Energizer, Panasonic, Toshiba, Varta and others so we have decided to do a little ranking by listing the top performing models in our tests in the various load scenarios we are using for testing. As a reminder we are using constant current load tests with 0.1A, 0.2A, 0.5A and 1.0A for the 1.5V AA-size Alkaline batteries, so we are going to rate the best batteries in four different charts as we’ve seen that one battery that performs very well under low load may not be the best with higher load and vice versa…

We are going to be updating these charts as we test new batteries in order to get a clear view of the situation with battery capacity and what batteries will work best for your specific needs. Have in mind that it is not always up to the highest capacity and you should always take into consideration the price of the batteries as well. For example if the second battery in the chart offers just 1% less capacity, but you can buy it for 30% less then you might sacrifice the minimal gain in extra capacity because of the much better price, so do have that in mind as well.
