Hi Brian,
Thanks for your email and for shopping on greenbatteries.com!
The Maha 9 volt charger is excellent for your intended use. We have many customers using it for that purpose exactly. Properly used a NiMH rechargeable battery will typically give longer service - per charge - depending on the application of course. We guarantee that you will like this combination.
FYI - Alkaline batteries are not well suited for high drain devices and the drain rate is significantly different for alkaline and NiMH rechargeable batteries.
Sincerely,
Curtis

Subject: Maha 9v charger
We are in need of rechargeable 9v batteries. I have just now started to research batteries, and your blog has been the absolute most useful resource that I've found. In my research, I've found that stock alkaline 9v batteries typically have a mAh of 600 or so. The most mAh that I've found in a rechargable 9v is 325. Does alkaline discharge at a different rate than NiMH? Would the battery life be different? I know that mAh is milliamp hours, so probably not, but I also heard that alkaline batteries aren't technically powerful enough for modern technology. Is that correct or did I misunderstand? We need to run wireless microphones and operating time is very important. With alkaline batteries, we know that we can run the microphone for x hours. I'm wondering if the use time will be significant.
When we buy, we are going to buy 8-10 batteries and a charger. The only charger on your site that I see is the Maha charger. After reading your blog, I saw that we would want to avoid rapid charging. I understand the reason behind this. The thing that concerns me is the specs on the Maha have a current rating for rapid charge and trickle charge. The charge time is not an issue for us, however, charging several batteries at once will be, so I am interested in a multi battery charger. Is the Maha charger a good charger? I haven't seen any bulk chargers, and I'm wondering if there's a good reason for that!
Either way, I know it will work out...
Thanks for any advice!
Brian
