I don’t personally use alkaline batteries, but for preparedness reasons, I like to keep a supply as backup and for giving away with my old loaners, so I store an untouched supply in the refrigerator.
I just updated my supply which I will keep for the next 10 years. My question is, are there any model variations within Rayovac alkaline batteries.
I bought the D 12 pack from Home Depot for example, and it is labelled Rayovac Model # 813-12PPD, but I also see other model numbers for Rayovac D batteries, such as Model No. 813-12PPSE, or Model No. 813-8RVPF2.
The D battery package from Home Depot doesn’t have “Ready Power” on it, none of the D battery packages seem to.
The shelf life, versus use by date, versus 10 year guaranteed freshness, and the use of “Ready Power” which seems to be defined as “10-year power guarantee (when in storage)”, and the lack of that on the D packages, all seems confusing, and perhaps a way of misleading people.
Can anyone unravel all these phrases, model numbers, and claims, by Rayovac?
good luck.btw some retailers get their own custom items that may differ only in model number.
and rayovac has i history of intentionally confusing marketing.
remember the 4.0 fiasco?
common nimh lsd cells that tried to make you think they were lithiums.
Thanks, I didn’t know about Rayovac’s “intentionally confusing marketing”, but I spent a lot of time trying to answer my questions before I posted this, and I couldn’t unravel it, it does seem to be deliberate.
How much batteries do you plan storing and how much does this cost you?
Wouldn’t it be more clever to get a dozen eneloops and a charger?
You would always have fully charged batteries with unlimited storage time(I don’t know how long eneloops last but there are some people still using the early models)
Or do you just buy them in bulk and use them in your devices to cycle them, with just a bufferstorage in case
I once seen a sheet from energizer or so in which they specify how fast they loose charge and it was considerably slower on less temperature, so the fridge idea is good.
Even the number written down are not 100% matching the graph so it seems to be always a rough estimation:
So at room temperature you will get 13loss after 5 years and 23 loss after ten years. If you store them colder like you plan I see no problem storing them for a decade…
Good to refridgerate but seal them in airtight packages.
Every time you open the fridge you expose everything to condensation.
Best if you use them regularly is to rotate stock.FIFO.
Anymore if an item doesnt use 18650 or aaa, aa nimh it gets relegated to loaner or giveaway status.i get enough batteries for remotes, ect from stuff I convert.
No longer stock alks.
I bought the batteries in bulk from Home Depot, a 60 box with 30 AA and 30 AAA, and a box with 12 D batteries.
I keep the batteries sealed in freezer bags, I have found that alkalines will store for very many years, and since they are only for emergency giveaways and loaners, and perhaps using in my own 12 and 15 year old long running lights that are no longer very important to me (IE Lightwave 4000, or Fulton angle flashlights with a Dorcy led bulb) , then I don’t want to rotate them, and since I don’t use them, I couldn’t rotate them anyway, without just throwing them away or giving them to someone else to just let sit in storage unused.
I don’t want to be passing out my rechargeable batteries to people, or even lending them out.
Even in the car I keep a cheap led flashlight and 3 AA alkalines for giving to someone on the road, I don’t want to be helping someone on the road while using my Fenix lights and Eneloops, and then when I have to drive away to continue on my own schedule, leave them in darkness.
If something happened that looked like a long time emergency, I would end up keeping most of the alkalines for myself, I have some lights that are immune to leaking, and that I might not want to use eneloops with, since they may over discharge, for example a 6AA holder with a 9volt plug that I can clip a Pak-lite flashlight on, or my Dorcy lantern that uses replaceable 4 D battery holders, and that I have put a Dorcy led bulb in, and that will run for a month on outdated D batteries.
My battery ‘stash’ is changing now that I’m doing rechargables, but the fact is that most folks still use primary cells so that makes for the best item to store for emergencies- either to help other folks out or for barter. My stash is smaller and I give away most of it at Christmas for kid’s toys; the rest I use myself so my stash refreshes itself annually and I renew it just after Christmas or as I go along.
