Like all good things that I find online, I found Batteryspace by using Google search engine. I was browsing and stumped to Batteryspace. They offer many types and kinds of recharge batteries from normal house hold battery to those hard to find that most electronic hardware store wouldn’t even carry. Their price were dirt comparing to other retailer. The combo or rechargeable batteries pack that caught my eyes the most was the 24 Pcs AA 2500mAh+12 Pcs 850mAh AAA High Capacity NiMH Rechargeable Batteries for the low low price of $35.99. You cannot find anywhere in store that sell 36 pieces of rechargeable batteries for any where under $100. After a couple of hours, yes I said hours because I want to get my money worth it, of browsing and going through the forum reading reviews, I decided I should go for it. So I did. My total came out around $40ish with tax and of course the 5% off by enter the promotion code “batteryspace” that I found on a coupon site.


The check out process was easy, fast, and secure.  Shipping took around 3 days after I placed my order. They sure shipped fast. My order consisted of 24 Powerizer Ultra high 2500mAh, not those 2100mAh, AA NiMH rechargeable batteries and 12 Powerizer Ultra high 850mAh AA NiMH rechargeable batteries. However, to my surprise, Batteryspace also send me a couple of battery holder for free. These batteries are excellent performance in Digital Cameras, CD Players, Remote Control Vehicles, Metal Detectors, Flashlights, PDAs. It sure did wonder for all my remotes in the house. My nephew asked me for some to use on his remote control car and boat. With these batteries, I save 2-4 bucks for every remote in the house just on battery alone. Powerizer claimed that their batteries will last up to 1000 charges, but then again, I don’t think I will charges that much; well at least for the next 10 years. Even if it does not get that far, two charges is enough to offset the normal Energizer. Plus rechargeable is a great way to stay green because you won’t fill you the landfill with dead batteries corpse. Another good thing about this battery is that they last up twice than ordinary NiCd battery. It was designed to enable rapid charging and long cycle life. However, like all rechargeable battery, they can’t hold the charge for long. So if you have an unused battery, you need to recharge it before use. Which is not a bad thing, it just a inconvenient that it is not always ready to go. But then again, rechargeable batteries benefits sure outweighed the normal alkaline batteries benefits. So give the world and the environment a helping hand and buy green because rechargeable are as green as you can get. If you want to help a bit further, go buy the solar battery chargers. But for Batteryspace, I will 110% sure come to them again whenever I need more any types of batteries. I would totally recommend it to all my friends and family. I know they would thank me for saving them moneys.

About a year ago I bought 12 of these batteries and got 6 free. After decreased performance I bought a MAHA MH-C9000 pro-recharger/conditioner to bring these batteries back to life. After putting them through the charger, in IEC mode (professional settings) it ended up with 11 of the 18 unusable for any application, another four were too low on MAH's to be useful for anything but a wireless mouse (under 100mah) and three came back up to charges between 1600 and 2000 MAH. IEC specs say that a battery should rate 20% to 30% above capacity. They were used in a variety of products from mice, remote controls to hard drive MP3 players and they have been cycled about 500 times (500 recharges on trickle chargers not fast chargers that lower life expectancy) so these are not long lasting batteries, but they are cheap and good sources of power for any lower current use products.
