Rated 4 out of 5 by from Replaced Defective BATT26L Rechargeable Battery My new crank radio didn't work. After a lot of troubleshooting, I determined that the battery was defective. I contacted Midland, but the representative didn't send me the replacement as she wrote in her reply email. I later decided to purchase a replacement battery because I wanted a working crank radio. The replacement and shipping cost me approximately $20.00 US. After a few weeks, the replacement battery was delivered to me. It arrived with a 50% charge, and it worked immediately after I installing it. I had bought a crank radio for my sister as a gift, and I hope that hers worked right away.

Rated 5 out of 5 by from Buy extras NOW! I bought 3 extra batteries as backups for my GoBag. I'd advise having at least a couple of spares around! Also, remember that Midland advises that these batteries are not meant to be charged in EXTERNAL rechargers (meant to be charged up in the ER310 ITSELF). Sign up for emails & get the 10% off! I'm ready for the zombie apocalypse!

Does the 26 in the part number mean it’s 2600mAh? And is that the largest capacity battery you sell?

Asked by: Jacob
Hello Jacob, that would be correct. The battery is specified as 3.7 VDC, 2600 mAh, lithium ion (Li-ion) and it is the largest capacity replacement battery we sell.

I purchased this for my ER210 radio. How are you supposed to connect the new battery to the radio? There is no wire to connect into the radio. Thanks for the help.
