I was looking for a 1.5v rechargeable battery for my U100 Door Lock. I believe this is the lowest price according to 3xCamel.
CamelCamelCamel.
Why did you post these? Nothing in your list is the same as OPs product.
Please cease posting this below deal posts, your comments over the past 12 hours have been mass reported as spam by the community. We already have tags below the deals where users can see previous deals for the same category and/or product, if they are missing then moderators will add them in time. XTAR-LC4, battery charger, rechargeable battery etc.
Thanks
THANK YOU.
i cant neg anymore of marshmallow :(

And he thought there is some great big conspiracy against him.
Nah, they recently found ChatGPT and they just want to use it for everything.
I also love the irony of someone going to this much effort to bitch and moan about a deal, but add nothing and has never posted a deal…
Door locks should last at least 12 months on alkaline batteries. Doesn't make sense to use rechargeables given the environmental impact and cost. 10yrs of alkalines is only 40 batteries. In 5+ yrs your rechargeables will be degraded
Not often you hear someone say single use batteries are better for the environment than rechargeables!
I assume you're only thinking about power usage to recharge the batteries but failed to compare it to power consumption, mining for materials, transportation & packaging required in order to make 40 alkalines. Not to mention what happens to them after they've been used.
Comments I've seen around the web regarding use of rechargables in smart locks are that the power levels that the locks require aren't really compatible.
The power level drop in rechargables means that once it reaches a certain level, the locks just stop working.
Whereas with single use, the lock is able to go through the usual low battery warning procedures.
That would be why most (all?) of them recommend not using rechargable batteries.
Ok good to know, thanks. Not disputing that at all.
Yeah, this is why you want to get rechargeable Lithium batteries for those uses (like this). They run at 1.5V for longer, rechargeables Ni-MH generally run at 1.2V so some devices think the batteries are dead when they are just not running at the right voltage.
Ok. Well food for thought because Ozbargain not Ozenvironment.. alkalines will be $20 cheaper over ten year lifespan
alkalines will be $20 cheaper over ten year lifespan…
YMMV my eneloop from 13years ago still usable and maintain 85% level of charge… not to mention bought it when Dickies sold like $1.50 a pop.
The ones in tv remote last charge was well over 4 years, not sure how you can get any cheaper.

DAFUQ did I just read??
Yeah, yeah, and wind farms gave me cancer form the low frequency vibrations. Why have solar panels when we have perfectly good coal in the ground…
These work great in my u100. They see to last forever.
Any battery only deals?
These batteries don’t touch the contact points in some devices. I used bits of afoil on the positive ends in my Schlage door lock.
I am wondering if the 4300 model of these batteries is worth the price difference ($30.90 for 4 only 4150 since I already have a suitable charger, compared to $36.46 for the 4300).
Based on capacity alone the price difference is not worth it but 4300 are newer and maybe have better circuitry and less RF generation.
These Li-ion AA batteries have a tiny voltage transformer built into them, to convert from typical lithium voltage to typical alkaline voltage, don't they?
Those transformers have a very small, but non-zero, power draw, which would eventually drain the battery.
In low-power situations (like when it's in a door lock, doing nothing for 99.99% of the day) that drain can sometimes be the most significant total drain, rather than the device its in. But it depends on the amount.
I wondered if anyone knows how much that quiescent current actually is?
ie. how many months would it take an XTAR battery to reach the low-voltage-warning level if otherwise not in use?
Ah I found reviews with some details.

https://goughlui.com/2024/08/28/mega-review-xtar-4150mwh-250…
For the 4150mwh version, around 16uA, and 19uA for the 4300mwh version.
This corresponds to taking around 260 days to use 10% of capacity, which is fine.
Is there a multi charger similar but adds 18650 and NiMH, with USB power or figure 8 240V?
