PolyMax HPC Batteries for Professional Two-Way Radios
Anyone who has run a long shift on a radio knows the feeling when the battery icon starts to blink. A firefighter is mid-evolution, a security supervisor is walking a large campus at night, and a crew lead is out on a job site far from the truck. A radio is only as dependable as the battery inside it, and a battery that quits early takes the whole communication plan with it.
New London Technology is a factory-authorized dealer and factory service center for the brands we sell, and our configurations are NDAA-compliant. Our PolyMax HPC collection brings together high-capacity lithium polymer batteries for popular Motorola, Kenwood, and L3Harris (Harris) portables. Browse the collection below, or call a radio specialist if you’d like help matching a battery to your fleet.
What Makes a High-Capacity Radio Battery Worth Considering
Capacity You Can Feel at the End of a Shift
Battery capacity is measured in milliamp hours (mAh), and in general, a higher number means more energy in the pack. You can see the difference across this collection. For the Motorola APX6000, there’s a 3400 mAh option and a 5100 mAh option. Kenwood TK2140 radios have a 3000 mAh battery and a 3500 mAh battery. The right choice depends on how long your people are away from a charger and how much talking, scanning, and transmitting they do.
If your team works short, supervised shifts with a charger close by, a standard capacity pack may be all you need. If your crews run 12-hour days, work a long way from a vehicle or station, or regularly cover big areas, a higher-capacity pack gives you more breathing room. Keep in mind that real-world runtime also depends on the radio, its settings, the temperature, and how often it transmits.
Why Lithium Polymer
The batteries in this collection use lithium polymer (LiPo) chemistry at 7.4 volts. LiPo packs are popular as replacements for radios that were originally sold with other battery types, since they can offer more capacity in a similar footprint. They’re a good fit for agencies and businesses that want to refresh older fleets without replacing the radios themselves.
Radios and Models Covered
The PolyMax HPC line covers a broad mix of professional portables. A few examples from the collection:
- Motorola: XTS1500, XTS3000, HT750, and APX6000
- Kenwood: TK2140, TK2180, and NX200 series radios
- L3Harris (Harris): XG-75P, XL-95P, and P7100 series radios
You can also use the filters to narrow the list by radio series or model. If you don’t see your exact radio, don’t give up. Our team can check what’s available, and we can often point you to a compatible alternative or a quote-based option.
Getting the Match Right
Always Start With Your Radio Model
Batteries aren’t one-size-fits-all. Two radios from the same manufacturer can look nearly identical and still take different packs. Before you order, find the full model number on the back of your radio or in your paperwork, and match it to the battery listing. Pay attention to the voltage, the capacity, and the chemistry, and check that the pack is listed for your radio and not just a close relative.
Don’t Mix and Match Across a Fleet
It’s tempting to buy whatever is cheapest or closest to hand, but a fleet with five different battery types is a headache. Standardizing on one pack per radio model makes it easier to track spares, swap batteries at shift change, and tell at a glance what each radio needs. Write down which radios take which battery, and keep that list somewhere your whole team can find it.
Charging Your Batteries the Right Way
A good battery needs a good charger. Batteries and chargers are designed to work together, so it’s smart to confirm that your charger supports the pack you’re buying. Our selection of two-way radio chargers covers single-unit models for individual users up through multi-bay desktop setups for stations, shops, and dispatch centers.
Think about how many radios charge at the same time. A small team might do fine with a single-unit charger on a desk. A busy agency with a shift change every eight hours will want a multi-bay unit that can handle a whole roster at once. If your people charge in vehicles, look at in-vehicle two-way radio chargers so portables are topped off between calls. We’re happy to help you pair chargers with the right batteries so nothing gets left out.
Taking Care of Your Batteries
A few simple habits can help batteries last longer and perform more reliably:
- Rotate your spares. Don’t let a spare sit untouched for a year, then expect it to work like new. Cycle batteries through regular use.
- Keep them cool and dry. Heat is hard on any rechargeable battery, so avoid leaving radios on a dashboard in summer.
- Inspect them often. Look for swelling, cracks, damaged contacts, or anything that seems off. If a pack looks damaged, take it out of service.
- Label and date. A quick label with the purchase date makes it easy to retire older packs on a schedule.
- Follow the manufacturer’s guidance. Charging and storage recommendations can vary, so check the documentation that comes with your radio and charger.
When You Need Something Different
PolyMax HPC batteries are great for everyday professional use, but they aren’t the answer for every situation. A few others are worth knowing about.
Hazardous Locations
Some sites, such as fuel facilities, chemical plants, and certain industrial areas, require equipment that’s certified for use around flammable gases or dust. In those places you’ll need intrinsically safe batteries that are approved for your radio and your specific environment. Don’t assume a standard pack will meet the requirement. Check the certification, and ask us if you’re unsure.
Fleet Monitoring
Some radio systems use smart batteries, which include built-in electronics that can report on the pack’s condition and charging history. If you manage a large fleet and want better visibility into battery health, they’re worth a look. They work with compatible radios and chargers, so confirm compatibility before you buy.
Backup Power in Remote Areas
For emergency kits or backup use in places where recharging isn’t practical, many teams keep primary lithium batteries on hand. These are non-rechargeable cells, so they’re not meant for daily use, but they can be a useful safety net when you need power and can’t plug in.
Buying for a Team or a Full Fleet
If you’re outfitting more than a few radios, a bulk order can simplify everything. We offer volume pricing, and we can help you plan the right mix of batteries, spares, and chargers for your roster. A good rule of thumb is to think about how many batteries you’ll need in rotation, then add a few extras for replacements and growth.
We also handle deployments of more than 1,000 radios, including staging, programming, and serialization, so a large rollout doesn’t land on your own team’s desk. If you need to match batteries to a mixed fleet of Motorola, Kenwood, and Harris radios, send us your list and we’ll sort out the right parts. For public agencies and contracts that involve procurement paperwork, our compliance page has documentation, and our team can talk through your requirements.
A note on availability: stock changes often, and a few models in this collection may show as sold out at any given time. If the battery you need isn’t available, request a quote and tell us your radio model. We’ll let you know what we can do and how soon.
Why Buy From a Factory-Authorized Dealer
Because we’re a factory-authorized dealer and service center, our batteries and accessories come with the support you’d expect from a company that works with these radios every day. Warranty repairs and service are handled in-house instead of being shipped back to the manufacturer, and our staff understands the radios you’re running.
Whether you need one replacement pack for a single radio or a few hundred for a department-wide refresh, New London Technology is ready to help. Request your PolyMax HPC battery quote today.
