Rechargeable Flashlight Batteries for Streamlight and Maglite
New London Technology is a factory-authorized dealer that supplies replacement batteries for professional flashlights used by public safety, security, and industrial teams. This collection offers rechargeable flashlight batteries for Streamlight Stinger, PolyStinger, and SL-20 series lights, as well as the Maglite ML5000. It is designed to help organizations bring tired flashlights back to full runtime without buying new lights.
Rechargeable flashlights are a core piece of equipment for officers, firefighters, security staff, and maintenance crews, and the battery is usually the first part to wear out. New London Technology stocks replacement packs built to the original fit and voltage for popular rechargeable light models. Our team also supports the radios, chargers, and accessories these crews carry, so one dealer can help you keep your whole kit powered.
Overview of Rechargeable Flashlight Batteries
Rechargeable flashlight batteries power the lights that crews rely on in low-light and emergency conditions. Over many charge cycles the pack loses capacity, runtime drops, and the light may dim or shut off at the wrong moment.
What Is Included in This Collection
This collection includes replacement NiCd battery packs for the Streamlight Stinger and PolyStinger (3.6V / 1800 mAh), the Streamlight SL-20XP (6.0V / 1600 mAh), and the Maglite ML5000 (6.0V / 2200 mAh). It also lists a heavy-duty in-vehicle mounting bracket for Endura EC1M series chargers, which is useful for vehicle-based charging setups.
Who This Collection Is For
Typical buyers include law enforcement agencies, fire and EMS departments, security companies, facility and maintenance teams, utilities, and equipment managers who maintain fleets of rechargeable flashlights.
Why Replace the Battery Instead of the Flashlight
A professional flashlight can last for many years, and the battery is a fraction of the cost of a new light. Replacing the pack restores performance while keeping trusted equipment in service.
Key Features and Benefits
Built to Match the Original Light
Each replacement pack is matched to specific flashlight models, including the Stinger, PolyStinger, SL-20, SL-20S, SL-20X, SL-15X, SL-20XP, and Maglite ML5000. That makes it simpler to find the right pack for your light.
Restores Runtime and Brightness
A fresh battery restores the runtime your light had when it was new. That means less time spent recharging and fewer lights going dark during a shift.
Cost-Effective Fleet Maintenance
For agencies with many rechargeable lights, replacing packs is far more affordable than replacing entire flashlights. It also avoids retraining staff on a new model.
Compatible with Existing Chargers
Packs are designed to the original specification, so they work with your current charging equipment when matched to the correct model.
Vehicle Charging Support
The heavy-duty in-vehicle mounting bracket supports Endura EC1M series chargers, helping teams create secure charging points in vehicles.

How to Choose the Right Flashlight Battery
Identify Your Flashlight Model
Check the model name on your flashlight, such as Stinger, PolyStinger, SL-20XP, or Maglite ML5000. Match it to the compatibility list on the product page.
Match Voltage and Chemistry
Confirm the voltage and battery type your light uses. The packs in this collection are NiCd, in 3.6V and 6.0V options.
Compare Capacity
Capacity is measured in mAh. A higher number generally means longer runtime, so pick the best capacity available for your model.
Plan for Charging
Make sure you have a charger or charging base designed for your light. For vehicle-based setups, consider mounting hardware that keeps the charger secure.
Technical consideration: NiCd battery care
NiCd packs perform best when they are used and recharged regularly. Follow the flashlight manufacturer’s charging guidance, and avoid leaving packs deeply discharged for long periods.
Technical consideration: proper disposal
NiCd batteries contain cadmium and should be recycled, not thrown in the trash. Use a local battery recycling program when you replace old packs.
Tips for Getting More Life from Your Flashlight Batteries
Keep Spare Packs on Hand
A charged spare pack lets crews swap quickly without leaving a light out of service.
Charge as Recommended
Use the charger designed for your light and follow the manufacturer’s instructions.
Store in Moderate Conditions
Extreme heat and cold affect performance and battery life, so store lights in moderate conditions when possible.
Replace at the First Signs of Decline
If a light dims quickly or runtime drops noticeably, it is usually time for a new battery.
