1.2V AA 3000 mAh VTEC Ultra Capacity 2 NiMH Battery Tests

16 Oct


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
