FREE Recycled Batteries

NOTE: Except for about 50 6-volt-maybe-3AH batteries that I don't think are very good, I basically don't have many batteries right now.   Via Christi Ascension Hospital just hasn't discarded many batteries this year, and the ones they have discarded as "bad" have truly been bad!-(

Skip the verbiage and go straight to the "what's available" list!

Hospitals use and discard LOTS of batteries!

For example, a mobile X-ray machine uses ten 12V-17AH sealed lead-acid batteries, each of which is about the size of a motorcycle battery and each of which consists of six non-replaceable 2-volt cells.   Over time and/or use, some cells lose their ability to hold a charge, and after enough cells have deteriorated such that the total voltage won't operate the X-ray machine, the hospital replaces the ENTIRE BANK!   Furthermore, to try to ensure they will never fail in use, many batteries, such as those which power IV pumps and UPS's (Uninterruptible Power Supplies), are replaced on a time-in-use basis even if they haven't yet failed.

Since the mid-80's, Via Christi Ascension Hospital (or whatever it is called this year:-) in Manhattan, KS, has given me their cast-off batteries.   Those which fail to remain above "nominal" voltage while supplying a current more than the C20 rate (the battery's rated ampere-hours divided by twenty) go to our local recycling center, while those which pass are listed below and are given (FREE of charge, of course) to users all over the nation (I once sent, via a HAM who was going that way, ten 12V-28AH batteries all the way from here in mid-Kansas to southern Florida for use during their hurricane season!)

Over the years, I've received all sorts of batteries, from monster 110-pound 12V-100AH batteries to 50-pound 120V-4AH batteries to ounce-size cells.   Most batteries are LEAD-ACID, but shrink-wrapped packs generally contain Ni-Cd, Ni-MH, or Li-ion cells, and some are so well encased that I don't know what they are!   Last month I received over a hundred "1/2 AA" which I'd never even heard of before, and 15 of them were still above 3.1 volts!   Once, long ago, I received some "wet" Ni-Cd's (think potassium hydroxide instead of sulfuric acid), and once I was given two humongous-big-and-heavy 5 KVA UPS's (the entire Uninterruptible Power Supply INcluding the batteries); these went to Kansas City and Nebraska for emergency HAM-repeater power!

The Hospital once gave me some 12V 40Ah Lithium Iron Magnesium Phosphate (LiFeMnPO4) batteries, with built-in battery-management systems, made by a company called "Valence".   They are direct replacements for lead-acid batteries at about half the weight, but they enter a "sleep" mode if they are allowed to discharge too far.   Valence offered to sell me (for hundreds of dollars!) a gizmo to wake them up, but a kind company representative suggested another method which I used to awaken most -- but not all -- of them.   Unfortunately, the Hospital hasn't discarded very many of them and I currently do not have any to give away.

Many of these "dead" batteries last for YEARS beyond their replacement date (in 2007, for example, I finally recycled a 12V-17AH battery which had been used to provide emergency communication for the 1996 International Horse Race), and some may die tomorrow!   But since they are FREE, you get what you pay for!-)

REMEMBER: There are NO guarantees on these batteries, so if you take one, you should take a second one (or more) because the first might fail!   And if you do take some, your ONLY requirement is to promise to recycle them properly when they finally do "die".

All batteries are FOB (Freight On Board) at 2001 Dunbar Road, Manhattan.

As of January 20, 2018, the following batteries are available

Depending on how often I want re-count batteries,
the ## (counts) in the following list are often old.

I usually also have "bad" shrink-wrapped Ni-MH and Ni-Cd PACKS in several cell
sizes ("A", "Sub-C", "half-AA", etc.), but you could make good packs from them
by disassembling and rebuilding them into whatever size & rating you need.

I once had a five-gallon-bucket of "D", "C", "AA", and "half AA" cells and 9V
"transistor-radio" batteries, but someone came all the way out from Kansas City
and took most of them!  There were even some batteries that looked like
"transistor-radio" batteries (same connector, almost-exactly the same size,
etc.), but they were Li-Ion batteries with a slightly-different output voltage.

The "D" "C", "AA", and "half AA" cells read 1.4V+ under a light load and the
"transistor" (9V) batteries read 8V+ under a light load (but you should NOT
even THINK about using the latter in fire/smoke alarms because they ARE *USED*
batteries and MAY FAIL earlier than expected!), but they are mostly GONE now.

NOTES:  "AMP-HRS" are taken from battery labels, but these are USED batteries,
         so their actual AMPERE-HOUR capacities are probably somewhat lower!

        "APPROXIMATE_SIZES" measurements were made with the terminals facing
         up and close to me; WIDE is the length of the side close to me.

If you are curious, you can see my battery-charging/testing workshop area

If you have a use for some of the above items, and if you'll promise to recycle them properly when it/they finally "expire", then contact me by email ( or phone (785-539-4448; Manhattan, KS). It's "First come, first served", and "come" is the operative word! Some miscellaneous WIRES and CONNECTORS are also usually available.
