Mighty Max Battery Mighty Max Battery ML22-12 - 12 Volt 22 AH, Nut and Bolt (NB) Terminal, Rechargeable SLA AGM Battery

I purchased these batteries as replacement batteries for my scooter. They are operating excellently to date.

Why did you pick this product vs others?:Price and previous experience brought me back to Mighty Max. This is my third battery. Two were used in UPS's and this one in my DR Brush Mower. Arrived ready to go. Fired up the Brush Mower on first turn of key. I will continue to use Mighty Max over other brands with my 3 experiences now of high quality products!

I bought 4 of these for some ICRA tents we use to perform work in hospitals. The fit was great. They hold and take a good charge.

Bought a new one of these in Jan 2023 for my JNC 660 and it went bad shortly after. I was going to write it off but I figured I'd take a chance on contacting the company. They were great. Sent them a copy of the amazon invoice and they are going to send me a new one ASAP. They asked me for the date code on the battery which leads me to speculate that Amazon is letting these sit on the shelf for too long. Anyhow thank you to Might Max for handling the problem quickly!

Used this to replace failing battery in a Catapiller jump starter (cj1000dcp) I bought from Costco. The original was a 19AH, but this 22AH fit without issue and provides a tad more battery backup.

Fit in my jump starter, works great better than new .A definite upgrade battery charged to full in under 10 minutes.

Bought this as a replacement for my Schumacher jumper box. Failed in that role. Fully charged it does not have sufficient amperage to jump start a 4-cylinder gas engine with a discharged battery. I have successfully used it as a short-term cordless battery maintainer (for use when programming modules, for example). Also, can be used to drive a vehicle with an inoperative alternator and a discharged battery to my service bay. A bit awkward in that role since it won't actually jump start such a vehicle, but it can be done with a little advance planning. So not entirely useless. In defense of the product, the description lists numerous applications in which this battery can be used. Replacement jumper box battery is not mentioned in the description.

I wasted no time doing recharging and discharging tests on this tough little AGM battery and the results were impressive :Mighty Max BATTERY RECHARGE TEST DONE USING A DELTRAN BATTERY TENDER PLUS CHARGER 1 PORT00 11.34 V @05:00 PM 08/07/2023 CHARGING STARTED01 11.84 V @05:31 PM 08/07/2023 STOPPED BY BLACKOUT02 11.84 V @05:39 PM 08/07/2023 RECHARGE RESUMED03 11.98 V @08:00 PM 08/07/2023 THUNDERSTORM KNOCKS OUT POWER GRID04 11.98 V @08:40 PM 08/08/2023 RECHARGE RESUMED05 12.28 V @11:00 PM 08/08/2023 VOLTAGE CHECK AFTER GREEN CHARGING LIGHT06 12.28 V @06:12 PM 08/09/2023 DELTRAN INTERNATIONAL CHARGER 2 PORT07 14.42 V @10:00 AM 08/10/2023 CHARGING ENDED WITH MAX CHARGE OF 14.42 V08 12.43 V @01:30 AM 08/11/2023 CHARGING STARTED09 13.01 V @11:00 AM 08/12/2023 CHARGING ENDED--------------------------------------------------Mighty Max BATTERY DISCHARGE TEST PERFORMED WHILE CONNECTED TO A BESTEK 400W POWER INVERTERINPUT: 12V DC 39.2AOUTPUT: 110V AC 60HZ 3.6A 400W INVERTERCONNECTED TO A 110V AC 0.23A AXIAL COOLING FAN0. 12.70 V @07:30 PM 07/22/2023 NEW BATTERY1. 12.72 V @01:06 PM 07/23/2023 AXIAL COOLING FAN START2. 12.70 V @01:31 PM 07/23/2023 AXIAL COOLING FAN STOP1. 12.65 V @05:07 PM 07/23/2023 AXIAL COOLING FAN START2. 12.56 V @05:24 PM 07/23/2023 AXIAL COOLING FAN STOP1. 12.56 V @11:31 AM 07/24/2023 DELL LAPTOP CHARGING START2. 12.54 V @11:45 AM 07/24/2023 DELL LAPTOP CHARGING STOP1. 12.54 V @03:54 PM 07/24/2023 AXIAL COOLING FAN START2. 12.49 V @04:10 PM 07/24/2023 AXIAL COOLING FAN STOP1. 12.49 V @11:55 AM 07/28/2023 AXIAL COOLING FAN START2. 12.44 V @12:15 PM 07/28/2023 AXIAL COOLING FAN STOP1. 12.40 V @04:52 PM 07/30/2023 AXIAL COOLING FAN START2. 12.38 V @05:00 PM 07/30/2023 AXIAL COOLING FAN STOP1. 12.38 V @11:00 PM 07/31/2023 AXIAL COOLING FAN START2. 12.21 V @12:04 PM 07/31/2023 AXIAL COOLING FAN STOP1. 12.21 V @11:23 AM 08/04/2023 SAMSUNG LAPTOP CHARGING START2. 12.12 V @11:32 AM 08/04/2023 SAMSUNG LAPTOP CHARGING STOP1. 12.12 V @12:43 PM 08/04/2023 AXIAL COOLING FAN START2. 12.01 V @12:15 PM 08/04/2023 AXIAL COOLING FAN STOP1. 12.01 V @10:43 AM 08/07/2023 AXIAL COOLING FAN START2. 11.34 V @01:09 PM 08/07/2023 POWERFAULT1. 13.34 V @02:35 PM 08/11/2023 ACER 5334 CONNECT LAPTOP 0% REMAINING2. 12.53 v @03:33 PM 08/11/2023 ACER 5334 DISCONNECT 72% LAPTOP BATTERY REMAINING1. 12.53 V @05:45 PM 08/11/2023 ACER 4720Z CONNECT LAPTOP BATTERY 10% REMAINING2. 12.38 V @06:06 PM 08/11/2023 ACER 4720Z DISCONNECT 43% LAPTOP BATTERY REMAINING1. 12.53 V @06:13 PM 08/11/2023 ACER 5334 CONNECT LAPTOP2. 12.43 V @06:26 PM 08/11/2023 ACER 5334 DISCONNECT
