for Citizen Eco-Drive 295-5 Solar-Powered Battery Capacitor 295-5100 MT621 5700, A100, B110, B117, BP10, E000, E001, E010, E011, E013, E030
Quick take
This SONXIAVIVO 295-5100 solar rechargeable battery/capacitor is made for specific Citizen Eco-Drive movement families, including MT621 and 295-51/295-5100 styles. It can bring an old Eco-Drive watch back to life when the capacitor has failed, but results depend on correct installation and movement compatibility.
Pros and cons
Pros
- Targets a defined set of Citizen Eco-Drive movement codes (including 295-5100 and MT621).
- Single replacement part, shipped as 1 battery/capacitor unit.
- Commonly used as a replacement for the 295-5100 capacitor style.
- Includes basic support claims (email support, money refund and replacement window are listed, but details vary by order).
Cons
- Not a universal battery, you need the right movement compatibility or the watch may not run properly.
- Some buyers report issues holding a charge, which may indicate installation position or an incompatibility for their specific watch.
- Eco-Drive capacitors can require meaningful time in light after a swap, so impatience can look like “bad battery.”
What buyers think
Buyer-review evidence is mixed but decision-relevant. Several reviews describe successful outcomes after replacing the capacitor, including watches that returned to normal operation after a period of charging in light. Multiple positive mentions point to the value of restoring a long-held Citizen Eco-Drive rather than replacing the entire watch. At least one review reports the watch ran in light but shut down in darkness, suggesting either a charge-holding problem or a fit/installation issue. Overall, the review pattern emphasizes that compatibility and correct installation matter as much as the part itself, while the long-term outcome appears positive for many buyers.
Who this replacement part is for
This is best for owners of Citizen Eco-Drive models that use the 295-5/295-5100 capacitor style (and compatible movement codes listed for MT621 and related variants). If your watch has stopped after years of normal use and you suspect capacitor failure, this part is a reasonable first place to look, provided you confirm movement compatibility.
Key specs and compatibility notes
Battery/capacitor type
- Lithium metal cell.
- Single-use replacement (1 unit included).
- Cell capacity listed as 19 mAh.
Compatibility claims to double-check
It’s marketed for specific Citizen movement codes and Eco-Drive family identifiers, including (as listed) 295-5100, MT621, 5700, A100, B110, B117, BP10, E000, E001, E010, E011, E013, E030, plus additional movement references.
Practical tip: Before you buy, match your watch model or movement number to the listed compatibility set. If you are unsure, take extra time confirming the movement code, because this is not a broadly interchangeable “same size” watch battery.
Pros and cons in real-world use
Why it can work well
- Eco-Drive restorations: When the old capacitor can no longer store energy, swapping to the correct replacement can restore function, especially if the watch is given time under light exposure.
- Part specificity: Being aimed at defined movement families can reduce the risk of choosing a random battery that does not match the circuit expectations.
Where buyers can get tripped up
- Charge-holding expectations: One review theme suggests a watch may appear functional in light but not remain running in the dark. While this could indicate a bad capacitor for that buyer, it also aligns with the idea that installation and contact quality are critical.
- Correct installation matters: Another review emphasizes that installation accuracy affects whether the watch holds charge.
Price and availability
Pricing can vary by seller and region. With the part positioned as a niche replacement, it may be more cost-effective than replacing the entire watch, especially for discontinued or sentimental models. If your watch is currently dead and you are considering repair alternatives, confirm compatibility and factor in the time and tools needed for a movement-level install.
Verdict
Choose this SONXIAVIVO 295-5100/MT621 solar rechargeable battery/capacitor replacement if your Citizen Eco-Drive uses one of the supported movement identifiers and you’re comfortable verifying compatibility and installing the part correctly. If you need a broadly compatible battery for an unknown movement, you’ll likely have better odds by pausing and confirming the exact movement code first.
FAQs
Is this battery compatible with all Citizen Eco-Drive watches?
No. It’s intended for specific Eco-Drive movement families and movement codes (including 295-5100 and MT621 styles). You should confirm your watch’s movement number or model is in the supported list before buying.
Will the watch charge immediately after installing?
Charging behavior can vary. Eco-Drive systems may need significant time under light after a capacitor swap, and at least some buyers emphasize that proper installation affects whether it holds a charge.
What capacity is listed for this replacement cell?
The cell capacity is listed as 19 milliamp hours (mAh).
Is the item a single battery or multiple cells?
It’s sold as a single replacement unit (1 battery/capacitor included).
If my watch won’t stay running, what should I check?
Given review themes, start with compatibility and installation quality (correct seating and contact). Also consider allowing enough time for charging in adequate light before concluding the capacitor is defective.
