Just like everything else, we need to take care of our rechargeable batteries to make them last longer and get the most out of them. Here are some essential care and maintenance tips for your Powerex rechargeable batteries.
BATTERY TIPS
USE THE RIGHT CHARGER:
Charge your NiMH rechargeable batteries with a SMART POWEREX charger designed for NiMH batteries only.
GENTLE CHARGE YOUR BATTERIES:
We always recommend charging your batteries at a slower rate whenever possible and if optional. It maximizes the battery’s life and its performance.
CONDITION YOUR BATTERIES:
Condition your batteries every 6 months or once a year if your batteries are not frequently used (if optional in your charger).
KEEP YOUR BATTERIES CLEAN:
Make sure the battery contacts and charger’s terminals are clean with no dust. You can clean them using a dry cleaning cloth.
STORE YOUR BATTERIES PROPERLY:
Store your batteries at room temperature in a battery holder and NOT in your charger.
END OF BATTERY LIFE:
If the batteries no longer provide adequate run time for your device, it is recommended to recycle and replace your batteries if the battery’s capacity is less than 60% of the rated capacity.

I have your Powerex MH-C490F Stealth Two-Hour Compact 4-Bank 9V NiMH Battery Charger. Is it okay to store my Powerex 9.6v batteries when they are not being used. I use them on a handheld device to control a model railroad layout.

If the batteries are not being used, we recommend storing them in a battery holder and not in your charger. We do carry 9v battery holders in case you need them, https://mahaenergy.com/battery-holder-for-4-9v-batteries/.
