Sanyo Eneloops are by far the best batteries you can use. Do a search on Eneloops and you will find there aren't many others that can compare. Also, you should consider a good charger. not just the little chargers that come with the batteries. The smart chargers make a big difference in battery life and when matching batteries with different measured capacities.
I use Imdedions and Powerex. Had some Eneloops but they were a) more expensive and b) didn't seem to last quite as long as these two. Rechargeables for me all the way 
+1 on the good charger.

There is a good article on the underwater photography guide (bluewater photo) that confirms my approach
NiMh high capacity batteries combined with a good fast charger are the best
I use annsmann 2850 mah with their fan cooled charger and it works great
Eneloop are better suited to the camera itself than the strobe

Basically you have to decide between low-self-discharge (LSD) batteries and high-capacity batteries. Eneloops are LSD batteries, their capacity is only around 2000 mAh, but they will hold that charge for years. Regular NiMH batteries come at much higher capacities, but they will lose up to 30% of their charge in the first 24 hours, might be down to 50% after a week and will be completely dead within a few months. In other words, if you don't use up your high-capacity non-LSD batteries right after being charged up, they pretty much lose their capacity advantage over LSD batteries.
I use eneloops. I had too many failures with various brands of high rate NimH, including the Powerex ones. I get at least two and usually three 45 minute to 1 hour dives on a charge and my fan cooled fast charger cranks them up in 15 minutes. I've been using the current set for over a year, which is typical. I periodically test them with a load charger to make sure they don't fail just when I've lined up a once in a lifetime shot.
I read an ad on one of the battery e-tailers (Battery Junction, I think) for new hybrid eneloops. They're low self discharge and high output. I intend to try them.

My Ansmann last on average 3 years and lots of trips
As I said the most informative article is here Batteries put to the test - best batteries for your underwater strobes|Underwater Photography Guide
You can see that if you have a high power strobe eneloop batteries are a good choice but for normal ones high Mah NiMh are enough
For this intova that seems rather weak despite the advertising NiMh high capacity should be adequate
