FREE Recycled Batteries

Via Christi hospital just gave me over a TON (literally!) of 12-volt 7-AH lead-acid batteries (forty-eight series-connected "8-packs").   Although I haven't had time to test/sort all of them yet, preliminary tests have not found ANY bad ones.   (This is not surprising; they were removed because of time-in-service and not because they were bad, which means they should probably give good service for several more years.)   PLEASE come get two or three (or more) and help lighten the load on the springs of my HALF-ton pickup!

For the other batteries, 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, batteries 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 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!

Recently, the Hospital gave me some Valence Lithium-iron-magnesium-phosphate (LiFeMnPO4) 12V 40AH batteries.   This is a new chemistry and I'm not sure how to test them properly, but some may still be available on special request.

Many of these 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 want one battery, you probably ought to take two or three (except for the LiFeMnPO4)!

If you take any, your ONLY requirement is to promise to recycle it/them when it/they finally do "die".

As of September, 2017, the following batteries are available

NOTE: (see list on left side) has LOTS of pictures, details, and (new) prices for LOTS of batteries!

Sometimes I 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.

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

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

If you have a use for one or more of the above, and if you'll promise to dispose of it or them properly when it or they finally "expire", then contact me by email ( or phone (785-539-4448; Manhattan, KS). It's "First come, first served", and you must come to my place to get them! Some miscellaneous wires and connectors are also occasionally available.
