Review: Works in Model 300 Tactical, But No Charging Indication LED - I like the Model 300 Tactical headset so much I purchased a US006-1 case LTGEM for Howard Leight Impact Sport OD Electric Earmuff Case, Carrying Travel Storage Bag with Mesh Pocket for Accessories and this optional Lith-Ion rechargeable battery. Both fit perfectly. One problem: both the headphone's and the battery's manual say that an LED should blink when being charged in the Model 300 Tactical headset and become solid after fully charged. I plugged the headset into multiple USB chargers and cords, but no LED blinked. I called 3M Peltor product support. They told me to send it back and gave me a prepaid RMA. They called back shortly afterward and told me the manual was incorrect. The Model 300 does not have an LED indicator. I guess you just plug it in overnight and hope for the best. So I should not have sent it in. They are sending me a new headset (though nothing was wrong with the old one) and a credit for a new battery as they for some reason don't want to send me the battery. What a pain. Bottom line: it's a great headset and the lith-ion battery works, but has no charging indication. Review: Well worth the expense... - I own the Peltor Tactical Sport 300 and when I started replacing the AA batteries every couple of weeks, I decided to purchase this battery. I was pleasantly surprised to see that this battery lasts longer than 2 AA batteries and not only it makes financial sense but I found myself a couple of times looking for AA batteries around the house and had to get to a store to buy more and that was getting annoying. I use them for competitions and I keep a power bank in my bag in case I need to charge my camera and I can use the same power bank to give these a quick charge if necessary. One problem I ran into is that this battery would not work because using the 2 AA batteries caused the contacts to bend and would not make contact with this battery. I used an owl tool to pry the contacts and since then, there is no problem. Note that the Peltor Tactical Sport 300 do not have a battery "charging" or "full" indicator, but using an amp meter I found that the battery fully charges within 5 hours and it stops drawing current from the charger so it is safe to plug them in and leave them plugged overnight. Overall, I think that it is a good addition to the Peltor earmuffs and if you use yours more than once a week, you will be happy you got this battery. ## Features - 3.7V 1000mAH 3.7Wh - Charge Voltage: 5.0V - Intended to power certain 3M hearing protectors - Compatible with the 3M WorkTunes Wireless Hearing Protector with Bluetooth Technology (Model #90542) - Compatible with the Peltor Sport Tactical 300 and Tactical 500 Hearing Protectors (Model #: TAC300, TAC500) - Includes USB charging cable ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06XDJHT5Z | | Age Range Description | Adult | | Apparel Closure Type | Adjustable, Snap | | Best Sellers Rank | #30,104 in Sports & Outdoors ( See Top 100 in Sports & Outdoors ) #30 in Hunting & Shooting Earmuffs | | Brand Name | 3M | | Care instructions | Dont clean | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 1,396 Reviews | | Fit Type | Over the Head | | Global Trade Identification Number | 00051125002790 | | Included Components | 1 battery pack | | Item Dimensions | 3.03 x 4.49 x 1.42 inches | | Item Type Name | 3M Rechargeable Li-Ion Battery | | Item Weight | 0.1 Pounds | | Manufacturer | 3M | | Manufacturer Part Number | ALPHA1100 | | Noise Control | Sound Isolation | | Noise Reduction Rating (NRR) | 25 Decibels | | Origin | Imported | | Pattern | Protector | | Product Style | Rechargeable Battery | | Single Number Rating (SNR) | 25 Decibels | | Size | One Size | | Style Number | ALPHA1100 | | UPC | 051125002790 | | Unit Count | 1.0 Count | ## Images ![3M WorkTunes - Image 1](https://m.media-amazon.com/images/I/712LolTjn4L.jpg) ## Available Options This product comes in different **Size, Style** options. ## Questions & Answers **Q: Will I damage battery A-1100 if left on charging cord for longer than a few hours** A: The battery will not be harmed if left on charge.
