Mobile Warming Extended Battery Pack 5 5 5 5
Worth the money I have the Warming Gear vest that I use for riding as well as hunting in the fall. The battery that comes with it was fine for riding back & forth to work on those cold days but just didn't last long enough. I bought this battery from Revzilla and it works great. It holds a charge for a really long time and the control is located on its own separate module which allows you to let it hang below my jacket. I can then adjust the settings without opening my coat. Definitely worth the extra money... January 19, 2015
This battery works as advertised I purchased the extend-life, increased amp-hour Mobile Warming battery for my heated vest. With the extended battery-pack I am able to utilize heat from the vest for at least 4-hours on a 100% setting. That period of time is all that I ever need for the colder early morning and early evening riding periods. During the daytime I can reduce the power to 50% and still remain comfortable.

For long term warmth. Cant beat the extended time that this battery allows you to be out in the cold. January 21, 2014
Great addition Little bit bigger than the reg battery and has the handy switch/wire. Fit's fine in a pocket. Glad I have it. May 13, 2013
Works great! Bigger, lasts longer! Love having a second battery. One for each pocket of my vest, and this one lasts longer than the small one. Perfect back-up battery for those colder days! April 19, 2013

Matthew J H: I currently have one of these, and it it nice to have an extended life battery on those very cold days. Jan 28, 2014

A shopper asked: Will this fit in the MW gloves? The pocket for the battery is tight. Jan 20, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Jami L: If the pocket is tight for the battery that came with the gloves (I'm estimating the size of the small battery off the top of my head that I got with my vest, but its 1.5'ish by 2.5'ish by 0.25'ish, then the large battery will NOT fit. The extended battery is quite large, but is does come with the extension piece so you may be able to put the battery on your arm. I do not know anything about the gloves, or if you would need two batteries-one for each arm. Jan 20, 2014

Duane K: I don't own the gloves but I do have the vest with the original battery it came with (same one the gloves come with) and I have the extended battery pack. If the pocket for the gloves battery is tight I really do not think the extended battery would fit. It's substantially bigger. I measured the original battery at 2 3/4 inches high, 1 7/8 inches wide, 7/8 inches thick. Extended battery is 3 1/8 inches high, 3 inches wide, 1 inch thick. Hope this helps Jan 20, 2014

Robert W: I do not have the gloves, but I do have the battery and the shirt. This battery does not fit in the shirt pocket. I would bet it would be too big for the glove pocket. The wire is longer and may make it work for you anyways? Jan 20, 2014

Stephen P asked: I've ordered the new gerbing 12v heated jacket liner and this battery. Are they compatible? Oct 20, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
Jon S: I would not suggest hooking up with 7V Mobile Warming battery to the 12V Gerbing jacket liner. That liner is designed to use more juice. If you have a 12V gerbing liner, you should get the heavier duty Gerbing 12V FlexPack battery (http://www.revzilla.com/motorcycle/gerbing-12v-flexpack-battery). It is designed to be used with that jacket. Dec 6, 2013
Reply to Jon Good answer? Yes (0) No (0)
Bill H: I do not know if it's compatible with the Gerbing, but it works great in my MW vest. Lasts longer than I expected, too. Oct 21, 2013
Reply to Bill Good answer? Yes (0) No (0)
GERRY D: The Mobile Warming pack is compatible with the Gerbing products. I probably would not buy this larger pack again because the wiring harness could be designed better because to eliminate the tangled mess in the pocket and the warranty is only 90 days, I would buy smaller packs as needed instead.

A shopper asked: Does it come with a charger to plug in the wall? Sep 21, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
David M: No it does not. You need to use the charger that comes with the original jacket/vest.
Be aware though, I purchased 2 of these batteries and had major problems with one, it would turn off constantly and not hold the charge.
I changed it for two of the standard batteries.

Bill H: No, it does not. It uses the same charger that came with your jacket and smaller battery. Sep 21, 2013

GERRY D: No charger included.

Battery and harness only.

A shopper asked: I am currently looking to purchase the Mobile Warming Classic Vest by Ansi. Will this battery extender work with with that vest? If so, anybody using this combo can tell me how effective it is in very cold weather as we can get in the mid-atlantic USA? Dec 2, 2014
Answer this · Send to friends Good question? Yes (0) No (0)
Michael R: I purchased a Mobile Warming Classic Vest by Ansi in early October and an extended 4.0 aH battery pack as well. I have ridden in temperatures ranging from 50 - 30 degrees with the vest temperature set at 25% - 75%. The battery will easily last for 6-hours at 75% and much longer at lesser settings.

The vest is of good quality and it is quite warm just by itself. I am satisfied with my purchase, but it would be better if the electrified area of the vest was a bit larger/longer (extending further down to the body mid-section).

Be aware that gloves from Mobile Warming Ansi will not work with the extended 4.0 aH battery because those batteries are physically larger than the standard batteries which are provided with the gloves. Thus, they will not fit into the small zippered pouch on each glove. The extended batteries can power the gloves if you are willing to place them in a cross-bar pouch or some secure location close to the hand-grips.

David M: Vest works very well in Australian winter, almost too hot.
I purchased 2 extended batteries, but both of them had problems holding a charge. After much frustration I swapped them for some standard batteries and all is well.

A great product, just don't buy the extended batteries.
