Maha Powerex MH-96V230 9.6V 230mAh Rechargeable NiMH Battery Review

Average Reviews:

(More customer reviews)I have purchased MANY of the 96V230 batteries to cycle through my wireless transmitters for my microphone and guitar systems (Sennheiser). I perform daily, and often have 3-4 one hour and 4 half-hour performances. I swap out each day and the batteries do fine. I have tried other solutions but got cut-outs. These batteries have been THE answer for me so that I can save money AND be nicer to the environment. I did have a problem with 2 of the batteries, one of which was dropped, but Maha replaced them under warranty very quickly for me with no hassle. The only other battery that I thought would meet my needs was the Ipower similar version to this battery, but I got scared off when I saw the oversize dimensions of the battery, which would not fit into my transmitter.

PowerEx 9V (MH-96V200) have 9.6V true capacity, compare PowerEx 9V batteries against many other batteries and you will see that they really are in a class of their own.

Energizer NH22BP ACCU 9-Volt Rechargeable Battery Review

Average Reviews:

(More customer reviews)I read the reviews by other people here and am wondering loudly whether they know what these batteries are for? they are Rechargeable batteries for high-drain devices that require higher mAh rating. NiMH batteries or NiCd batteries do not hold charge like an alkaline battery so if you have charged an NiMH battery and put it in say an alarm clock, the batteries will lose charge in less than a month. they are for immediate usages like digital cameras where you need high mAh batteries and that digital cameras drain batteries. its more like "spend it immediately" battery unlike the disposable batteries that discharge in a circuit but drain very slowly when not in a circuit. I use Energizer AA batteries for my digicam and they recharge the flash much faster than even the best disposable batteries. A best guide is to look whether the appliance for which you are buying this battery is listed on the package or is identical to those on the package. this 9V would be a great thing for a toy where the battery drains out fast and you cannot afford disposable ones everyday.
Just a note: If the device is a direct draining one like a motor and not in a solid-state circuit, do not use a rechargeable battery since if they are completely drained, they cannot be recharged.
