12V 7.5AH LEAD ACID BATTERY

Replaced dead battery in APC 400W UPS, exact size & Amp/Hour rating. No problems

If you open up your average UPS (uninterruptible power supply) you will find one of these batteries. They are easily replaced with nothing more than a screw-driver. This is a great deal since the UPS I have was over $100 and the battery it came with only lasted 3 years. Hopefully I'll get another 3 years with this battery! This battery is also used in many other back-up power situations such as lighting & fire alarms. I've also used these batteries while camping. If you connect a 12v solar panel and a cigarette lighter socket to one of these you can charge it all day and then use it at night for light and for charging cell phones (or you can charge it with your car if you're worried about someone stealing your solar panel while you hike. It charges almost instantly when connected to a running car and then you can carry it down to the campfire). This battery is not suited for applications which require enormous amounts of current (don't connect it to a trolling motor or a 1000w sub woofer, for example). For something like that buy a car-battery-shaped deep-cycle battery. You have to keep those upright because (like a car battery) they are not sealed so acid will leak out if you tip them, but you can get a 35aH for about $35 and those can handle huge amounts of current.

It is almost a direct replacement for the Peavy TAXI portable amp. It fits exactly and is rated one amp-hour more, which is a plus. It works great at a great price! What more could you want?

I purchased this battery for a "homebrew" digital clock (BIG!), that I and a friend built, about 30 years ago! The internal, rechargeable, Midland 12V battery failed a long long time ago... The clock failed recently! Now I find more and more uses everyday for this battery! I test (12V) assembled kits on it. I prefer NOT to connect it to my variable P/S...AC and all!
I use it on small to medium motors. solen- oids, etc. I will be getting me another soon! KD5BIH

I got two of these to replace the dead internal batteries in my Tennis Tutor 2 tennis ball machine, and so far they're working great. The machine draws between 2-6 amps depending on the ball speed, and I'm getting at least a couple hours on a charge. I'm charging them with the Duracell 2A charger from All Electronics, # BC-80 and that works well too.
