Hi Dave, it's best the ask this question to the manufacturer of the battery pack since they would know the most about the battery pack's characteristics. If this is a Tenergy 8.4V battery pack please reach out to our team at [email protected] with your battery pack information and we can help provide you with the ideal charging voltage.

@@TheTenergybattery i mean what is the voltage on fully charged 8.4v nimh?? a 7.4v lipo is 8.4v at full charge. and a 11.1v lipo is 12.6 at full charge so does the voltage of nimh and nicad go up at full charge? this charger is the first one i ever had with a screen and did not touch a nimh pack for years back then my reedy quasar did not have screen.. batt was done when warm lol

NiMH will likely work, but the run time won't compare to alkaline or lithium 9 volt batteries. Also, a NiMH in a smoke detector will likely need to be recharged frequently throughout the year. Feel free to reach out to use direct at [email protected] if you're looking for suggestions on which 9V batter is ideal for a smoke detector.

@@TheTenergybattery I was thinking maybe the balancing rate cant keep up with the charging rate - I don't know. I should probably be using a higher power charger for these batteries anyway. Either way, thanks for following up.

We would actually suggest you reconsider the Centura and instead swap them for our Solla batteries which are designed for solar lights which work in -4°F to 122°F degrees. Your main challenge in the winter will be keeping the batteries charged so that they don't overdrain. During the winter there is already less light, and with cloudy days or snow the solar light might not make enough power to recharge the batteries. If you're having running into a week of no sunlight due to weather, we suggest taking the batteries out and recharging it on a NiMH/NiCd charger to prevent over-draining it.

check out one of our newer videos on this charger where we show how to connect the battery pack with the charger kzfaq.info/get/bejne/eruRi6iTv9WaomQ.htmlsi=LLA11_BhpEBPXPvA

Greetings, you can follow the steps that start around 3:57 to see how to discharge your battery pack with the TB6B. Time stamped link: kzfaq.info/get/bejne/oZeaZJB3p823Y3U.html

Discharging a Ni-Mh battery before recharging it is fine, just remember to not leave an empty battery inside a device or it can over-discharge which is not good for the battery.

@@TheTenergybattery Thanks for the answer but let me explain better because I didn't explain myself well: When the camera turns off because the batteries are exhausted (exhausted for the camera), I take out the batteries and connect them to a small incandescent light bulb and I leave them connected until the light goes out completely, then I recharge them. Is it correct or is it better to recharge the batteries as soon as I take them out of the camera without completely discharging them with the light bulb method?

Generally it's recommended to store the battery around 40-50% charged. For Nimh and Nicd the voltage will be around 1.28V-1.2V. If you're unsure and would like more info, please reach out to our team with your battery pack's specifications at [email protected] and our team can help provide more info.

Greetings, when charging a 1S Lipo battery pack you can skip the balance charging instructions and just choose LiPo CHARGE instead. If you have any additional questions or aren't sure how to recharge your battery pack, feel free to reach out to our team directly at [email protected] and we can help guide you through the process and assist you with any concerns you might have.
