charging, I didn't figure he'd need it. Thanks for the suggestion,
though.




When the charger shuts off, the battery voltage will slowly (more or
less) drop to the lower trip point. Whilst in that region, the
comparator could "chatter". I always use a bit of positive feedback in
a circuit like this to avoid the chatter.
