This article reveals Maxell’s new all‑solid‑state battery power module designed to match the size and output of traditional ER batteries and what it might mean for devices and fleets that rely on long‑life backups. priority pass report reveals offers more context.
What Maxell built and why it matters
Maxell, Ltd. has introduced an all‑solid‑state power module that fits the physical dimensions and output voltage of a standard ER battery (lithium thionyl chloride type). In plain terms: this module aims to be a drop‑in replacement for many devices now using non‑rechargeable ER cells, while adding the benefits of rechargeability and integrated control.
Core features at a glance
The module pairs eight of Maxell’s mass‑produced PSB401010H all‑solid‑state cells within a casing matching ER battery dimensions (17.9 mm diameter, 50 mm height). It delivers roughly 35 mAh of usable capacity and keeps the output at the familiar 3.6V, while incorporating a charging circuit that accepts 5V input.
Why the matching size and voltage is a smart move
- Compatibility: Devices built for ER batteries can adopt the new module with minimal or no redesign.
- Reduced maintenance: Rechargeable backups cut down on frequent battery replacements in the field.
- Lower waste: Less single‑use battery disposal means a smaller environmental footprint.

Maxell’s module
| Parameter | Typical ER (Li‑SOCl2) | Maxell All‑Solid‑State Module |
|---|---|---|
| Nominal voltage | 3.6 V | 3.6 V (output matched) |
| Size | ER standard (Ø 17.9 × 50 mm) | Same ER‑size casing |
| Capacity | Varies; typically non‑rechargeable high‑capacity | ~35 mAh (rechargeable) |
| Rechargeability | No (primary cell) | Yes (charging at 5 V via integrated circuit) |
| Environmental impact | Higher (disposable) | Lower (reduced waste) |
Practical implications and typical applications
ER batteries are commonly found in industrial backup systems, smart meters, and IoT sensors. Because they are primary cells, they necessitate scheduled replacement—think of regular site visits and the labor cost and logistical hassle that come with them. A rechargeable ER‑sized module promises to shift that dynamic.
Where this makes a difference
- Smart meters and grid sensors: fewer site visits for battery swap-outs.
- Remote IoT sensors: longer continuous service with opportunistic recharging.
- Industrial backup clocks and memory retention: stable voltage with top‑off capability.
- Rental fleet infrastructure: keyless entry backup, lot environmental sensors, and remote monitoring nodes can see improved uptime and lower maintenance costs.
A quick anecdote
Funny story: once I visited a car rental lot where a downed sensor had delayed vehicle returns for a morning. The tech on site joked that if every sensor had a rechargeable brain, their mornings would be a lot calmer.

That simple scene captures the human side of this tech—less time chasing dead cells, more time on the road.
Advantages and limitations
The module highlights several benefits but also comes with realistic boundaries:
- Advantages: improved maintainability, reduced environmental waste, compatibility with existing ER‑size sockets, and integrated charging for easier system design.
- Limitations: lower raw capacity compared to some primary ER cells, the need for a charging source in the device or system, and potential cost considerations during initial deployment.
How this ties to car rental operations
In the rental world, tiny things add up: a sensor that keeps a charged state reduces the chance of a misplaced key fob, a gated lot entry that stays online prevents check‑in chaos, and telematics that never drop data cut disputes over damage and fuel. For rental companies and platforms like GetRentacar.com, more reliable backup power in small devices can mean smoother reservations, cleaner records, and fewer headaches for customers and agencies alike.
Future roadmap and broader tech context
Maxell says it is advancing all‑solid‑state designs with a focus on high reliability, heat resistance, high output, and larger capacity. The company is also exploring combinations of solid‑state batteries with wireless power transfer and energy harvesting—think ambient light, vibration, or RF trickle charges—to further reduce maintenance demands.
Potential system integrations
- Fleet telematics modules with trickle charge from vehicle systems.
- EV charging kiosks using solid‑state backups for payment terminal retention.
- Keyless entry and immobilizer backups inside remote key fobs and gateways.
The usual caveat applies: a promising module is only part of the story; integration, testing, and real‑world cycles will determine whether deployments truly pay off.
Summary and takeaways
Maxell’s ER‑sized all‑solid‑state power module is a pragmatic innovation: it keeps the physical and electrical footprint of the ubiquitous ER cell while adding rechargeability and modern charging electronics. For industries using dispersed backups—utilities, manufacturing, and rental fleets—the potential to reduce battery waste and maintenance time is a meaningful win. Still, capacity and charging logistics will shape real adoption curves.
