Digital camera reviews of Maha Powerex MH-96V230 9.6V 230mAh Rechargeable NiMH BatteryDigital camera Review: Maha batteries are TERRIBLE!!! Summary: 1 Stars
I bought 2 Maha 9 volt batteries because I bought an item that needs almost continuous 9 volt power. For this usage, the manufacturer said a 9 volt battery should last about 100 hours. The first battery I used was a non-rechargeable Energizer. That one actually lasted close to 200 hours. I was impressed, but in need of a more long-term solution than buying more and more Energizers. When my 2 Mahas arrived, I put one in and it lasted about 100 hours. No big deal, I thought. The instructions say that they usually become longer-lasting after a few charges (WRONG). When that one ran out, I put in the second one. It lasted about 8 hours. I was a bit pissed off, but I figured that I only needed that one to get by while the other one recharged. So I kept using them, and instead of lasting longer, they worked for shorter and shorter amounts of time. After FEWER THAN 10 CHARGES, they both last less than 6 hours. These batteries are functionally USELESS to me. I had read reviews about some of Maha's batteries being duds. When the one originally lasted 8 hours, I was convinced that one of mine was a dud. After recharging them both several times, I am convinced that both of them are duds. Maha is badly in need of quality control. I regret buying these batteries. Something this expensive should do what it says. Maha should go out of business. I can say unreservedly that I HATE THEM.
Digital camera Review: Powerful DV battery Summary: 4 Stars
I speak with the use of an electro larynx. When a battery goes dead, I'm left speechless. Because the Maha PowerEx is more powerful, I can set the volumn level down, which helps it hold a charge. And it holds its charge longer than the other brands and models I've tested. I'm sticking with this one.
I gave it 4 instead of 5 stars because the case has come off. I don't know if this is dangerous. I just slide it back on and go on with my business.
And another issue common to all the batteries I've tried: they will burn out and melt down in my pocket. Ouch! And I've not been able to find a convenient carrier made for these guys. My solution--I don't carry spares, so I appreciate the longer charge life of this model even more. I'm going to order more of these.
Digital camera Review: TOP POWER!! Summary: 5 Stars
Quite simply: TOP POWER!! This 9Volt, (actually 9.6 Volt), battery holds it's charge nicely and powers a MIDI Controller keyboard for longer than the original 6-AA battery array (that was the original configuration). I figured that, after the 6-AA holder broke and, seeing as how the keyboard was old enough now that no replacement parts for it existed, I added up the 1.2 volts x 6 AA batteries and came up with 7.2 volts. I knew that a lot of people complained that many 9V batteries were only 7.2v to 8.4v, and that this POWEREX was a full 9.6 of honest, unadulterated power. As long as your intended device(s) can handle the full 9.6V, I highly recommend this battery. It is awesome. At under $12 apiece, it might seem expensive, but for you you get, trust me, it is worth every penny. All other 9V rechargeable batteries are inferior.
Digital camera Review: The best for my paintball hoppers/markers Summary: 5 Stars
These batteries last and work great. I can't say enough about these batteries. The power output doesn't fluctuate and they don't slow down until they are completely drained. I also use the Maha charger with this battery.
Digital camera Review: The real deal Summary: 5 Stars
9.6 volts. Great stuff. Initially I purchased other brands of rechargable batteries for some electronics I have which call for 9 volt batteries, but they didn't even power one of my items. This is because they are rated for something like 8.4 volts, and I was told that it may be even lower. These work great, and this company has some really nice chargers as well, which charge in around 2 1/2 hours and automatically switch to a trickle charge to avoid overcharging and to keep the batteries optimally charged. I didn't see it here, but I found a 4 battery charger which is perfect for my needs.
