    Replaced a manufacture battery on my monitor. Now my device works like a new. Almost replace it with a $3000 unit. Product rep was quite disappointed I am sure. I am sure the unit will continue to work for some time.My Welch Allyn device is a bit older and I needed to modify the connectors to attach to this battery. However this was only a small problem.

    Excellent battery. Purchased two of them for my emergency lighting. They charge and hold their charge. I have tested both emergency lights by turning off the power to the circuits while gone for a couple of hours. Upon return the lights were still operating. Circuits were powered again and the batteries charged.

    worked out well. In fact, my other Welch Allyn device battery gave out right after I ordered the first one.Quick delivery and at a fraction of the price the Welch Allyn sells it for!

Battery fires up our 24 year old Tundra like a champ. Great packaging too.

I just received my Mighty Max XTY14 BS for my Honda TRX 300. It came quickly and well packed. After considerable research I decided on the Mighty Max because of the reviews, because of the build quality, and the warranty.

Powerful little battery!

Ordered a Mighty Max ML22-12 , Sealed Lead Acid AGM battery from the Mighty Max store on Amazon. Arrived well packed and double boxed with no damage. Had 12.7 volts surface charge when I got it. Using this as a replacement for my Schumacher SJ1332 Jumpstarter. The ML22-12 is a 12 Volt 22 Amp Hour battery and is the same size as the original 18 Amp Hour Schumacher battery and fit perfectly. Construction appears identical. The Schumacher was made in Vietnam and the Mighty Max is made in Thailand. Mighty Max also makes an 18 Amp Hour battery this size (ML18-12), but figured the 22AH should provided some extra capacity in the same physical space. After installation, the meter on the Schumacher Jumpstarter indicated the Mighty Max battery state of charge was 95% as shipped. The built-in charger took about 18 hours to get it to 100%. So far happy with it. The original Schumacher battery lasted about 7 years. Hopefully the MightyMax will provided similar service.

The enclosed picture is the old mighty Max battery. I liked it so much. I bought another just like it to ensure my backup generator starts when the power goes out!

Battery arrived timely and in perfect condition. Installed into my 2005 Honda ST1300 and fit perfectly. Fired right up! Put it on trickle charge overnight to top it off. Very happy with this product.
