Official specifications:
  • Rechargeable Times:Up to 500 times
  • Type:Li-ion
  • Model:RCR123
  • Capacity: 650mAh
  • Output voltage:3.0V
  • Internal resistance:80

This battery is a not a normal LiIon battery, it uses ICR chemistry, but the output voltage is closer to IFR chemistry, this is because there is a diode inside the battery to reduce output voltage.
On Soshines website the charger voltage is specified as 3.6 volt, this is too low to get full capacity. I did my tests at 4.2 volt (3.6 volt nominal), 4.4 volt would probably have been better, but I will not go outside the specifications.

With this battery I am really missing a charger specification printed on the battery.

The two batteries does not match in capacity and without protection in the battery, avoid use them in series.

The battery does not have any protection, i.e. if it is over discharged once, it will be damaged and might also be dangerous.

The charge curve looks funny, due to the diodes and the low charge voltage.


Conclusion

The advantage of a diode is more capacity for a 3.2 volt battery, but I do not really believe it is a good idea, because the diode will generate heat at high loads and you can get real IFR batteries with about the same capacity (At least when you follow the charge specifications).

I’ve never tried these diode-modified cells but it seems that using the LiFePO4 cell would be less complicated. Thanks for doing this review.

Soshine RCR-123 3.0V Li-ion 650mAh…..This is the battery used in my dog’s electric fence collar. Is it safe to use any other battery as a replacement? I’ve been having trouble with these and with the charger.

I would expect that any IFR (LiFePO4) battery could be used, but they have slightly lower capacity. They do also require a special charger.

You can see some of them in my CR123 comparison article.
