Customer reviews for PowerEx Stealth Two Hour 4 Bank 9.6V Charger w/3-9.6V Batteries
The product is built very good, the charger give you red and green lights to let you know the batteries are depleted or charged, I would give this product 5 stars if the batteries would power the security camera for about 4 hours, they last about 2-3 hours, but the camera signal is stable until the end of the charge. I hope this is helpful.
PowerEx Stealth Two Hour 4 Bank 9.6V Charger w/3-9.6V Batteries Review by HMMWV "God, Country, Corps" (santa clara, CA USA)
I first bought this system for use with wireless microphones that eat 9vdc batteries and do not perform well with the 7.2 volt rechargable nicad cells. The problem has always been that with the same number of cells inside the 9v stack at 1.2 V instead of 1.5V you loose .3 V x 6 cells or 1.8 volts which drops the typical rechargable cell from 9V to 7.2 V.
Transmitters don't work well on 7.2 volts of typical rechargable "9v" batteries. You also tend to want a fresh charge on your battery before use which is where this product comes in.
It adds an extra cell to get you 9.5 volts which is typical of normal batteries.
The con: The batteries are only about 230-250 mah instead of the alkaline 500 mah so you do not get the same runtime. The charger is well made and indicates when the cells are charged.
These are recommended for use when you know that you want a charged battery and don't mind recharging it when done (example using it for a wireless mic). The higher voltage will make the product work well and you won't be wondering if the battery is fully charged or not - you will know it is full every time. For people who use alot of 9V batteries, this will pay for itself in a short amount of time.
PowerEx Stealth Two Hour 4 Bank 9.6V Charger w/3-9.6V Batteries Review by Sylviane Rokab "Sylvie Rokab" (Pacific Palisades, CA USA)
I work with audio production and needed rechargeable 9V batteries for my wireless transmitters and receivers. Those batteries didn't work at all with my Seinheiser transmitters and worked only for a short time with my receivers. I just called Maha Energy (the manufacturer) who told me they'd replace the charger and batteries. But since the charger seems to be working fine, I'm having doubts that I got 4 malfunctioning batteries. What are the odds of that happening? Anyway, just thought I'd let you know so you don't go through the same hassle I did. I guess I should stick with the renown brands even if they cost more.
