Primary Lithium Batteries for Two-Way Radios: Power You Can Count On Off the Grid
Some jobs don’t come with an outlet. A wildland crew spends a week on a ridge line with the nearest road hours away. A search team is out through the night after a storm has knocked the power out across three counties. A utility lineman is working a remote site where the truck is a long hike from the work. When recharging isn’t an option, the radio still has to work. That’s the situation primary lithium batteries were made for.
New London Technology supplies primary lithium batteries for professional two-way radios, along with rechargeable packs, chargers, and accessories. We’re a factory-authorized dealer and factory service center, our configurations are NDAA-compliant, and we offer volume pricing for agencies and businesses that need to stock up. Browse the collection below, or call a radio specialist if you’d like help matching a battery to your radios.
What Is a Primary Lithium Battery?
Single-Use Power With a Long Shelf Life
A primary battery is one you use once and replace. Unlike a rechargeable pack, it isn’t designed to be plugged in and topped off. The batteries in this collection use lithium manganese dioxide chemistry (Li-MnO2), and they’re built for radios that need dependable power without a charging routine. Many crews like them because the packs can sit in a gear bag or a vehicle for a long stretch and still be ready when called on, though exact shelf life depends on the pack and how it’s stored.
How They Differ From Rechargeable Packs
Rechargeable batteries are the right choice for most daily use. You charge them at the station, swap them at shift change, and get hundreds of cycles out of each one. Primary lithium batteries trade that convenience for something different: grab-and-go readiness. There’s no charger to carry, no outlet to find, and no waiting. For many teams, they work best as a backup alongside their regular rechargeable packs, not as a replacement for them.
Where Primary Lithium Batteries Make the Most Sense
Wildland and Remote Field Work
Long assignments far from base are a natural fit. A crew heading out on a multi-day assignment can toss a few primary packs into a bag and not worry about charging. The same goes for survey teams, forestry crews, and anyone working in terrain where power is hard to come by.
Emergency Kits and Disaster Response
When storms, floods, or outages hit, charging stations can go down with everything else. Keeping primary lithium batteries in a go-bag, a response trailer, or an emergency operations center gives you a reserve that doesn’t rely on the grid. Many agencies and businesses include them in their continuity plans for exactly that reason.
Cold-Weather and Long-Duration Work
Cold can be hard on rechargeable cells, and lithium primary chemistry is often chosen for outdoor use where temperatures drop. If your team works in the cold for long stretches, it’s worth asking about it. We can talk through what has worked for other customers, and you should always check the manufacturer’s specs for your radio.
Utilities, Security, and Infrastructure
Utility crews, security patrols, and infrastructure teams sometimes need a battery that can sit in a truck box for months and still be ready. A primary pack stored properly can fill that role, giving a dependable backup if a rechargeable battery fails or a charger isn’t nearby.
Batteries We Carry
This collection is organized by radio brand and model, so finding a match is simple. Right now, the listings include options for the Motorola XTS3000, HT750, and APX6000, the Kenwood TK2180, and the Harris P5400 series and P7100. Packs are rated at 9.0V, with capacities running from about 3,000 mAh up to 4,500 mAh, depending on the radio.
Availability on individual packs can change, and some items may show as unavailable at times. If you don’t see the exact model you need, send us a quote request. We can check with our suppliers, confirm compatibility, or point you to a close alternative. We also work with agencies that want to buy in larger quantities for a season or an emergency stockpile.
Building a Mixed Fleet Plan
Few agencies or businesses run radios from a single manufacturer, and most have a mix of rechargeable and backup power. Here’s how a few of the brands we carry fit into that picture.
Tait for Utility and Industrial Teams
Utility, transportation, and industrial crews often rely on Tait Communications equipment. If your people carry Tait radios, our Tait page is a good place to start for batteries, chargers, and accessories. The primary lithium listings here currently center on Motorola, Kenwood, and Harris models, so for Tait fleets, tell us your radio and we’ll confirm what’s available.
BK for Public Safety and Government
BK Technologies radios are common in public safety, utility, and government fleets, especially where multi-band flexibility matters. The BKR9000 is a multi-band P25 handheld that works well for crews who need to reach more than one band. As with any radio, check that a battery is approved and compatible with your specific model before you buy.
Mobiles and Vehicle Setups
On the vehicle side, the BKR9500 Multi band mobile radio brings similar flexibility to patrol cars, trucks, and response units. Mobile radios draw power from the vehicle, but the handhelds your crew carries when they leave the truck still need dependable batteries. That’s where a backup primary pack can save the day.
Choosing the Right Backup Strategy
Count Your Radios and Your Days
Start with the basics. How many radios will be out at once, and for how many days? A crew of five on a three-day assignment will need a very different supply than a single dispatcher covering a weekend. Think about transmit habits, too, since heavy talkers go through batteries faster. It’s always better to bring a little more than you think you’ll need.
Keep Primary and Rechargeable Packs Separate
It sounds simple, but mix-ups happen. A primary pack and a rechargeable pack can look similar, and putting a primary battery into a charger can cause serious damage. Label your packs clearly, store them in separate bags, and make sure everyone on the team knows which is which. A bit of colored tape goes a long way.
Match Voltage and Fit
Voltage and connector style matter. The packs in this collection are 9.0V, which fits the radio families listed, but not every radio will accept every pack. Check the label under your current battery or your radio’s manual, and send us the model number if you’re not sure.
Using and Storing Primary Lithium Batteries Safely
Never Try to Recharge Them
This is the most important rule. Primary lithium batteries are not designed to be recharged, and trying to do so can be dangerous. Never put one in a charger, and never connect it to a charging circuit. If a pack is depleted, replace it.
Store Them Cool and Dry
Heat shortens the life of any battery. Keep spares in a cool, dry spot, away from direct sun and out of a hot vehicle cab when you can. Leave them in their original packaging until you need them, and avoid letting loose packs touch metal objects like keys or tools.
Check Before You Head Out
Before a long assignment, look over each pack for damage, dents, or corrosion. If something looks off, don’t use it. Pack a few extras, and consider carrying one or two in a separate pocket so a single bag mishap doesn’t leave you stranded.
Dispose of Used Packs Properly
Used lithium batteries shouldn’t go in the regular trash. Check your local rules for battery recycling or hazardous waste drop-off, and set up a simple collection bin at the station or warehouse so spent packs don’t pile up in a drawer.
Tying It All Together
Keep Your Plan in Writing
A good backup plan is easy to follow under pressure. Write down which radios your team uses, which batteries fit them, and where spares are stored. If your fleet includes a BKR9000 handheld and a BKR9500 Multi band mobile radio in the same unit, list both so nobody has to guess in the field.
Order as a System
Agencies that standardize on BK Technologies or Tait Communications gear often find it easier to order batteries, chargers, and accessories together. Fewer part numbers mean fewer mistakes, and it makes reordering faster when your spare stock runs low.
Factory-Authorized Support and Volume Orders
