My 2 old boats were originally 12v lead acid batteries and i simply swapped them to 12v lifepo4 batteries without issues. Was the best change to my batteries i ever made, had them for years and never replaced unlike the lead acids i replaced every year.
The only thing to note is the previously mentioned sudden death of the battery going flat. Lead acid will slow to an eventual crawl, lithium will work and then simply stop.

Okay, so I took the back off one of my alarms so I could tell you the exact battery model and it seems I lied! They are Duracell 2500mAh rechargeables, but they are NiMH not lithium. Seems I suffer from memory loss more than the batteries
. However, on the plus side they definitely work in the Wolf alarms!
Sorry for the curved ball. But I definitely have lithium batteries in my Nash barrow!

Problem with most nimh AA rechargeable batteries is that they are normally only 1.2v when normal AA batts are 1.5v. If the device being powered is sensitive to voltage they complain about being low charge almost straight away.
There are 1.5v rechargeable AA but they're more expensive than normal

That makes sense. My Duracells are only 1.2v and the Wolf alarms show only 60% or so charge right from the get-go when they are fully charged. But they don't mind that it's 'only' 60%, and it stays at that level for weeks on end.
Battery science is way more complex than my small brain can accommodate, but I'm happy that I've found a solution that works for me, helps the planet a little and saves me £££.

You're as bad as me

I heard a pop one night in the down stairs cupboard when I opened the door this was the result.
It had gone bang whilst charging my Headtorch as a result I threw these all away along with the two head torches

It's called thermal runaway and its the bain of my life when managing buildings I've lost count of the amount of fire safes I've had to buy to store lipo and Ion batteries in
