Our lithium battery packs power oceanographic instruments for long deployments. They last three times as long as alkaline batteries, and they also outlast other lithium battery technologies. Since 2004, we have delivered more than 4000 battery packs, and they have been highly reliable. Our packs go into ADCPs, Argo floats, gliders, and other instruments. They power deployments in warm equatorial waters, and in arctic ice. They have powered ADCPs for two year deployments, and they will power Argo floats for a decade.

Doppler Ltd. has lithium battery packs designed specifically for Teledyne RDI ADCPs, Nortek ADCPs, and Rowe Tech ADCPs. We recently began to supply battery packs for Scripps and MRV’s Argo SOLO II floats. The original plan was to progressively transition from the old packs to ours, but ours perform so much better that these floats now use only our battery packs.

SeaSpider lithium battery packs

Workhorse ADCPs in an OceanScience Sea Spider frame measures ocean waves. Ocean wave observations demand a lot of energy, and these deployments often use lithium batteries.

Our battery packs are designed for specific instruments on the basis of how they draw power. They are designed to supply the maximum power an instrument requires while maintaining a steady voltage throughout the duration of a deployment.

We design battery packs in collaboration with Tadiran Batteries, in Israel. The packs we provide in large volume are manufactured in Israel by Tadiran, and low volume and custom packs are assembled in the US using Tadiran’s components. Large packs also include a safety circuit, which Doppler Ltd. manufactures in San Diego.
