Affordable Double C size Extended Life Primary Lithium Cells from PowerStream
New! Re-designed for HDD applications.
Used with Digitrak Horizontal Drilling Locators and Ditch Witch beacons
NEW: The PowerStream Double-C is the only Chinese Double-C cell to have passed UN Transportation testing UN38.3. See the certificate below.
NEW. Starting in Spring 2013 the PowerStream Double-C battery has been redesigned to perform even better in harsh environments. This improved cell is exclusive to PowerStream.
Note: The extraordinary shelf life of these cells is not reduced if the batteries are partially used. In other words, you can use 10% of the life of the battery, let it sit on the shelf for a year and it will still have 90% of its life left. Note 1: The battery voltage will stay above 3 volts for entire discharge when discharged at 200 mA or less.
Quantity pricing is based on one order, one shipment.
Water or drilling fluid penetrating the battery compartment can simulate a bad battery.
Why is it that we can ship thousands of cells to the largest drilling companies in America with no reports of complaint, but another crew has a rash of failures?
A sonde with corroded terminals can make it look like the battery is bad, or exhibit short battery life. With 100mA current flow and 4 ohm contact resistance the voltage drop will be 400mV, dropping the effective battery voltage from 3.2V to 2.8V. Since power is amps times volts, the sonde will try to draw more current to compensate for the voltage drop, which causes even higher voltage drop. So 4 ohms of contact resistance can waste 30-50% of the battery life.
If water ever penetrates the battery compartment you have an immediate problem that should be resolved. Make sure that the battery compartment is cleaned completely of moisture, make sure that the contacts are shiny, and that the seal is good. Getting the fluid out of the sonde should be done with a vengeance, or you will be stuck with replacing the expensive batteries more often until the sonde fails completely. If the O-ring is damaged, replace it, if the sealing surfaces are damaged consider using teflon tape to enhance the seal.
Our crew has been using the PowerStream lithium cells in our DCI sondes for 6 years without a hitch. These cells are very cost-effective and excellent performance. SG Montana.
We use the PowerStream cells for our Ditch Witch electronics. The specs match what our Ditch Witch beacons require, and they work perfect in the field.PM Michigan
Since the PowerStream Digitrak Sonde cells work so well, we have stopped using the Digitrak Supercell. We have been using the PowerStream Double-CH exclusively since 2008.AJ-T Canada
In our terrain we often run into hidden gravel deposits. If we run out of battery we have to pull the sonde and (due to the gravel collapsing) we have to drill the hole again, putting us behind schedule and off-budget. PowerStream's batteries pay for themselves. WG Michigan
Sonde transmitters are used as sonde locators or beacons by horizontal directional drilling companies, and require extended life lithium batteries and drilling supplies. These earth boring machine operators use Digitrak sondes and transmitters with portable boring machines to do horizontal drilling under roads, parking lots, canals, and under landscape that cannot be trenched. We have been suppling battery drilling supplies for trenchless drilling locators for many years and supply many of the big horizontal drilling companies, as well as hundreds of local trenchless drilling companies.
We have been purchasing these batteries over the last couple of years and have had great success with the batteries typically lasting over a month. --DE New England
