Subject: Re: poly six Battery replacement mods.

Well, the reason for the replacement is so that when you replace the
battery with a non-chargeable kind, like the lithium style, the
circuit doesn't charge it, causing it to explode.

The original battery is Ni-Cad and someone had the idea that it should
be charged rather than using a replaceable battery.

As for 3.6, I don't know if .6 volts is that big a difference but I
would play it safe. You could probably tell by looking at the
datasheet for whatever part is being charged by the battery.

Hope that helps!
