Re: HP 22 - Batteries Message #3 Posted by Randy on 29 Oct 2003, 7:13 p.m., in response to message #1 by Peter S. Dworkis
The original HP AA nicads were 700 mah. These are still made by Sanyo, see the pages here on batteries. You can sub 1100 mah nicads as well, just allow for 50% longer charging times.
You can of course use alkaline and lithium AA's - but under no circumstances should the charger be anywhere near the unit when you do this.
You can also use the super-extended capacity ni-mh rechargeables at 1850 mah - but you must recharge externally. This is really the best way to preserve your 21 or any woodstock as plugging in a unit with a dead or missing battery is the most common way to kill it.
