2005Batteries/Power forum

21 years old. Gear and prices may have changed since.

DisputedParticipants disagreed and reached no conclusion. Read the findings as positions, not as an answer.

Batteries that repeatedly flash red and green lights during charging may have temperature stability issues and will resume normal charging once they cool to suitable operating conditions.
Moisture or condensation inside batteries can prevent charging until conditions stabilize, typically resolved by waiting for temperature normalization.
Batteries kept off their chargers for extended periods can develop internal imbalances that prevent charging, and continuous charger connection is recommended for long-term maintenance.
ProPac 14 and HyTRON 120 batteries are not compatible with older chargers lacking LCD displays, requiring newer interactive charger models for digital battery support.
Recelled batteries have a typical service life of about 18 months and may not restore the fuel gauge display functionality since recalibration cannot be guaranteed.
Two HyTRON 120 batteries provide approximately equivalent runtime to four ProPac 14 batteries with reduced weight.
PAG chargers with revitalization programs can potentially rebalance severely imbalanced cells in older batteries before returning them to standard chargers.
Battery age of 12 years indicates they are at or beyond their expected service life and may no longer perform reliably.

The discussion involves batteries that are 12 years old, making findings specific to aged nickel-cadmium battery chemistry.
Some participants disagreed about whether recelling is economically justified compared to purchasing new batteries.
Temperature control and humidity levels during storage and use were discussed but not definitively tested.
No consensus was reached on optimal upgrade path between recelling, purchasing new ProPacs, or switching to HyTRON models.
Recommendations about PAG charger revitalization were presented as anecdotal workarounds that the manufacturer did not officially endorse.
