Ask at your drug store's photo counter for an APS battery. That's the right type. >Now, the control panel settings are preserved normally, BUT the IIGS clock >does not advance! > >I looked at another IIgs Rom 1, and its battery is 3.6v DC. > >Which battery voltage is optimum???? 3.6V. >BTW, I SOLDERED the battery to the leads ---no hassle. >(I could never understand why "clip-on" was work $14 bucks!) > >Steve Buggie >631 McKee Drive >Gallup NM 87301 Probably to make money, of course! An APS battery should cost about $7. Since you are soldering, you might as well solder a holder for the battery. It is not a good idea to apply too much temperature to a lithium battery. It might explode.

The actual low-load voltage for a couple new AA cells is going to be around 3.2V. A problem with using two AA cells is that you are likely to get a fairly short useful life. A typical 3.6V 1.2AH Lithium battery is good for at least 5 years. The Nite Owl Slip-On battery in our IIgs is on its 7th or 8th year. Lithium batteries are a lot cheaper than they used to be. All Electronics (800-826-5432; http://www.allcorp.com ) generally offers 3.6V 2.5AH Lithium batteries with wire leads for less than $4.00. Rubywand
