Always Good to Carry a Spare

By John

This review is less about my purchase and more about the product. I just picked up a spare battery for my Sea Dragon 2500 Video Light. There is nothing wrong with the original battery I purchased three years ago; it charges fast and still hold a charge. I just like carrying a back-up. Good product, good system. While I've experienced issues with other aspects of the DC-1400 system (and Sea-Life's product support has always been great!), The power system of the Sea Dragon has performed flawlessly. From a purchase standpoint, I think B&H Photo was faster than Prime. 'nuff said.

I've only had chance to recharge on arrival. Recharged fine. Will update after 1st dive trip.

This produce doubled the life of my Dive Light - needed a second battery to do two dives between charging. Great product! Fast shipping with B&H!

The SeaLife camera is waterproof, but the battery compartment for the light isn't, so it pays to have a spare battery just in case you get a leaky o ring. Tough to go to an exotic locale to dive & have a camera that works, but loose your only battery

Excellent substitute for more expensive GoPro batteries.

Used often on recent dive trip to Roatan. Easily lasted 1 and sometimes 2 dives, 40 - 55 min each with many photos and videos.

i would buy product again when other light is purchased.

Excellent package for Seadragon underwater 1500 light. Now having two batteries allow us to enjoy a full boat trip for two scuba tanks; and also be prepared or a night dive. Very satisfied with light/battery combination. A full charge gives you a nice 60 minutes trouble free photography underwater trip.
