What I could really use is an effective alternative to disposable 2CR5 batteries
for the PZ-1p.

Some people may have done that before, - but just in case, - I thought I'd share
this tip.
I remember that some people on the list were using La Crosse ("smart") charger
for AA and AAA batteries. (I bought it originally for the
flash light, primarily, but then used for all other needs.)
I have the older model, the blue one, I believe BC-700, but from what I've read,
- all their models suffer from one problem:
When the battery is depleted so that its voltage is below some threshold (I
believe, it is 0.5 V), the charger displays "null", and refuses to charge that
battery.
The workaround I've found is to use a cheaper charger (I have a Duracell-branded
"fast charger") - to "jump-start" that battery.
So, you insert your batteries (whatever quantity is needed in that charger, in
my case, - it takes batteries by pairs), including
the "faulty" one, and charge it for a little bit.
E.g. today, I had one battery showing 0.4V, and after about a minute in that
"fast charger", it was ready to be charged in La Crosse.
(I've done that with other rechargeable batteries too, -not only with the
"strange" one that I am describing below.)
And since we are talking about rechargeable batteries, - I've found that
recently, my "Amazon Basics" branded rechargeable AA batteries started behaving
strangely: sometimes one (or maybe even two sometimes? I don't remember for
sure) battery becomes drained to that low level, like today, 0.4 V, while the
other three are still at a reasonable level (today those 3 were at about 1.28 V).
The curious thing today, that after just about a minute in the "fast charger",
the voltage of this battery went up to about 1.3 V, and after that it was
behaving as it was the same as the rest.
There could be two possibilities: either this battery significantly lost
its charging capacity, or it is just was "locked up" in this strange state of a
low voltage, and this "shock charging" helped to get it out of that.
The latter is very likely, as the pencil charpener where these 4 batteries were,
stopped working very suddenly, not gradually.
I haven't seen anything like this happening with any other brand of rechargeable
batteries.
In any case, I am using my La Crosse now to "refresh" this battery
(discharge-recharge cycle). That, hopefully, will show the true capacity of the
battery.
I hope this information could be helpful.
Cheers,
Igor
