Based on Stonedeaf's info that the APOC circuit uses relays, a battery with one quarter the current spec of the original battery may not trip the relays, or trip just a few times then go dead.
This is just a hunch, so you may want to try the lithium batteries and see how long they last in actual usage.
If they are pin & size compatible, any battery is better than no battery.
Good luck
