Thirty years upstream of the spec sheet.
Most battery vendors read the smart battery specification. Our engineers helped write it — inside Energizer, alongside Intel and Duracell, before "smart battery" was a category.
The spec itself
Co-created the SMBus, smart battery, and smart charger specifications with Intel, Duracell, National Semiconductor, Linear Tech, Maxim, Toshiba, and Varta.
Inspired Energy
The team becomes Inspired Energy: standard N, P, and S-Series smart packs adopted by OEMs worldwide.
One facility, everything
Design, molding, electronics, assembly, and test under one roof in Newberry, Florida — serving OEMs worldwide.
We literally wrote the book on smart batteries.— and every pack we ship still follows it, to the letter.
Pick a pack, or start from a blank schematic.
Standard SMBus batteries and chargers ship fast. Custom programs get an engineering team that has taken hundreds of OEM devices from concept to certification.
Smart battery packs
Standard N, P, and S-Series lithium-ion and NiMH packs with true SMBus fuel gauging — the packs OEMs design in when accuracy is not optional.
Browse packs →Smart chargers
Level 2 and Level 3 SMBus chargers matched to our packs — single to multi-bay, desktop to embedded, ready for the cart, the case, or the dock.
Browse chargers →Fuel-gauge boards
Embeddable gas-gauge and safety electronics for OEMs building the pack into the device — our spec-author electronics, your enclosure.
Browse boards →Rough-spec your pack in ten seconds.
Pick a chemistry and a voltage. We'll sketch the cell math — then a real engineer turns it into a real battery.

NOMINAL VOLTAGE
RUNTIME PRIORITY
Estimates use representative cells (18650-class Li-ion, AA-class NiMH). Your device's duty cycle, peak current, and enclosure change everything — which is exactly the conversation to have with our engineers.

When the device is a patient monitor or a defense system, the battery is not a commodity. It's a safety-critical subsystem — and it deserves a manufacturer that treats it that way.
Medical
Power for patient monitors, surgical lighting, ventilators, and infusion systems — engineered for the devices your compliance team answers for.
→Military & Defense
Rugged, USA-built packs for comms, optics, and field systems where supply-chain provenance is part of the requirement.
→Aerospace & UAV
High energy density and precise fuel gauging for platforms where weight is budgeted by the gram.
→Robotics
Smart power for autonomous platforms that need state-of-charge data as much as they need the charge itself.
→Handheld Instrumentation
Compact SMBus packs for analyzers, radar, and test equipment that work a full shift in the field.
→One roof in Newberry, Florida. Zero hand-offs.
Most battery vendors assemble other people's parts across an ocean. We run a vertically integrated facility: injection molding, die stamping, electronics pick-and-place, label printing, pack assembly, and test — one building, one team, one quality system.
That's why our packs are proudly designed and built in the USA, why engineering changes take days instead of quarters, and why you can call and reach the person who actually made your battery.
