Revive Your Electronics with Reliable Memory Backup
Is your industrial equipment losing its settings every time the power cuts out? Or perhaps your vintage computer can no longer keep the correct time? These are classic signs of a dying CMOS or Real-Time Clock (RTC) battery. The 3.6V 80mAh Ni-MH Battery is the precise solution to restore the heartbeat of your critical electronics.
Built for Durability and Performance
Unlike standard disposable batteries, this Nickel-Metal Hydride (Ni-MH) stack is rechargeable and designed for long-term "trickle charge" applications found on circuit boards. It features a high-stability design that withstands the variable temperatures often found inside computer cases and machinery control panels.
Seamless PCB Integration
Replacing a soldered battery requires precision. This unit comes pre-fitted with 2 robust solder tabs (pins) designed for vertical mounting on Printed Circuit Boards (PCBs). This ensures a vibration-resistant connection, essential for machinery and devices that move or vibrate.
Why Choose This Replacement?
- Direct Replacement: Ideal substitute for standard 3/B80H, 3/V80H, and similar 3.6V button cell stacks.
- Green Energy: Ni-MH chemistry is more environmentally friendly than older Ni-Cd alternatives and suffers less from "memory effect."
- Versatile Application: Trusted by technicians for repairing everything from ham radios and PLCs to car key fobs and server motherboards.

FAQ Section
FAQ Section
Q: Will this replace a VARTA 3/V80H battery?
A: Yes, this battery typically serves as a compatible functional replacement for the 3/V80H and 3/B80H series used in many legacy electronic applications. Please verify your pin spacing and polarity before purchasing.
Q: Does this battery come pre-charged?
A: Ni-MH batteries may lose some charge during storage. We recommend installing it into your device and allowing the device's charging circuit to top it up for 24 hours for optimal performance.
Q: Can I use this for a computer motherboard BIOS?
A: Yes, many older industrial motherboards and vintage PCs use this specific 3.6V barrel-style battery for BIOS/CMOS settings retention.
