A little over a year ago, I shared my experience recharging alkaline batteries. What a game changer that became!
In the ensuing year I have learned a lot about the practical side of recharging alkalines; mostly that after a few recharge cycles, they tend to leak. This is especially true of those cheap Kirkland brand batteries from Costco. Actually, lately those Costco batteries tend to leak even when they are brand new so I avoid purchasing them entirely.
I have also learned that when the battery recharger says BAD, the battery really is bad. Being stubborn, I will often set the bad battery aside and try it again later. Sometimes it will charge up but for the most part, I send them off to the recycle box.
Something we tend to overlook is that when a flashlight or gizmo is dead – meaning, of course, the batteries are dead – there is often only one dead battery and the others in the device are okay. So how do you tell? I use this inexpensive battery tester gizmo I purchased for testing batteries. It is nothing fancy but for less than $4, what would you expect? Anyway, it just works.
When I find an assortment of partially used batteries, I top off the okay batteries in my recharger and they are good to go for another round. And the dead batteries? I try to re-charge those as well and in the past year, have experienced about a 70% success rate.
Note: Recharging dead alkaline batteries is different from recharging “bad” batteries.
I have been thrilled with both the alkaline battery recharger and my cheapie testing device. To learn more, here is the original article for your education and enjoyment.

Bargain Bin: Just a few related items today for your consideration.
Maximal Power FC999 Universal Battery Charger: This nicely built charger will charge charge AA, AAA, C, D, N, 9V, Ni-MH, Ni-CD, and Alkaline batteries. It has an LED display so that when you first put a battery in the charging bay, you know whether it is viable for charging or simply bad and ready to go back to the recycle box. Note: When I purchased the charger, it was on backorder. Oddly, it actually shipped the next day. Go figure. Anyway, I am really sold on this charger.
SE BT20 9-Volt Battery Tester You definitely should consider a battery tester even if you decide not to re-charge your alkalines. The advantage of having a tester is that when a gizmo dies, you can determine whether just a single battery is discharged and not the complete set. I now own 3 of these and stash them around the house.
SODIAL(TM) Battery Tester Volt Checker for 9V 1.5V and AA AAA Cell Batteries: This tester has a numeric display – something worth considering although may take two to three weeks to arrive. As I write this, it is a bit more than $5.00 with free shipping.
AA / AAA 4 Cell Battery Storage Case (Bundle of Six Cases): I like these little cases. I put a sticker on the outside of the case indicating that these are re-charged batteries. About $6 with free shipping.
Solar 11-in-1 Battery Charger: This is a universal charger that does what it is supposed to do. It uses sunlight to generate a current that charges pairs of batteries in sizes AAA, AA, C, and D.
