AOLIKES 3.7v 720mAh Battery for Sena SRL, SRL 2 Motorcycle Bluetooth SHOEI Neotec II, GT-Air II, SP51, SP55 Bluetooth Communication System SRL 2-Wire Battery Replacement

I purchased this battery to replace the battery in my Sena 20S BT headset, which I have been using at least weekly since 2017. Last week while riding, I noticed that it was not holding a charge for more than a few hours, even though it had been charging overnight. I took it apart and discovered that the battery was “swollen” and needed to be replaced. I ordered this battery on Amazon after verifying the model number, etc. The battery dimensions and connector are identical to the SENA OEM one. It fit perfectly into the tray and the battery itself appears to be of similar quality as the OEM unit, at least from a visual inspection. I have not personally confirmed its advertised amperage. I plugged it in to verify that it was charging normally for about 20 minutes, before reassembling the headset. I found no indication of delamination, swelling, or felt any heat buildup whatsoever on the battery surface. So far, so good. If anything changes after a few weeks of use, I will update this review. Good luck.

I was a little hesitant, not buying OEM, but it was in stock and the reviews were good, for the 950 mAh model, so I ordered it. Install was easy, peasy, had it installed in about 3 minutes and charged it right up. Worked perfectly and lasts longer than the battery that was in my Sena 20 from new. I'm very pleased with the battery, I was a little hesitant buying the larger size, but I first purchased the smaller capacity one that was supposed to be for my unit and it was dying after about 4 hours or riding. Sent it back after the first ride and ordered this one, fit and worked perfectly and it lasts all day riding and then some. Great choice, easy to install (have to break a little plastic piece off inside the head set to install it or any of them, but that was easy), works perfectly! Will buy again, when this one goes down, probably in 3 years...

This was a little bigger than the OEM battery, but it fits (barely). Holds a charge and works well. Would buy again for Sena 20S

A bit of online searching told me this was the size, voltage, and capacity of battery I needed to replace the old stock battery in my Sena SMH5-FM headset. However, I was hesitant to buy this battery since there were no reviews. It caught my eye because it was less expensive than several other similar batteries that had fairly good reviews. Ultimately, I figured these batteries probably all come from similar factories in China, so I decided to give this one a shot. The battery was delivered in two days and was packaged well. On arrival, the voltage measured 3.94 volts which is normal for a partially charged 3.7 V lithium battery. I disassembled my SMH5 and was happy to see that the batteries were nearly identical in size. I was also happy that the polarity of wires to the plug was the same for both batteries. You will see in the description of this battery and in reviews for other similar batteries that occasionally the polarity of the wires is switched. If you get a battery like that, it's not a big deal. You can switch the wires yourself in a few minutes, but it was nice not having to do that. I secured the battery in my SMH5 using a small piece of double-sided tape and reassembled the SMH5. The entire process took me less than 10 minutes. I gave it a quick test run to make sure it was working, then plugged it in to fully charge. Once it's fully charged, I will take it through a few charge cycles to see how it holds up. If there are any problems, I will update my review. But based on my experience so far, I give it five stars. If you are buying this battery for a Sena SMH5 or SMH5-FM, you will need a size T7 torx (star) screwdriver to open the headset and a small piece of double-sided tape to secure the battery in the headset. There's a good write-up online if you need it.

I hate to leave negative reviews, but this product is being falsely advertised as being a direct replacement battery for the Sena 10S and 20S! See included collage photos with measurements included. The battery with the letters "XK" on it is the OEM battery that is being replaced. The battery with the letters "LP" on it, is the battery from this seller. The last collage shows the measurements of where the battery needs to be placed. The 1st and second photos show the width and length measurements. The replacement battery from this seller is not only 1.09mm wider than the original OEM battery, it is also a WHOPPING 3.07mm longer! While these amounts don't seem like much, they mean the world when it comes to small handheld electronics. The last thing you need is for a battery "bouncing" around inside a handheld electronic device! The last image shows the maximum length and width measurements for the battery to sit flush on the circuit board where it needs to be attached via double sided tape. The replacement battery is 1.68mm longer and .7mm wider than the maximums allowed for the battery to sit flush with the circuit board. I'm returning this battery along with the one I got for a 10C as it too is exceeds the maximum dimensions to fit properly. DISAPPOINTED!!!

Llegó en el plazo indicado. Paquete perfecto. Funciona correctamente en intercomunicador para casco Sena SHM05.

Bought this for a Sena 30k. Original was 850mAh, but this is the same size and has the correct plug. Easily fitted, after review of You Tube video. Charged up ok and seems to work fine so far.

Bonjour la batterie de l intercom SF4 avait des problèmes pour tenir la charge .J’ai donc acheté ce produit qui est bien arrivé à un détail près c ‘ est qu il ne correspond pas à ce qui est indiqué sur l’emballage est dans la description du produit j ai donc reçu un 950 mAH à la place d’un 850 mAH et l origine c’est un 650 mAH.il se monte comme même mais vous pouvez constater qu il est plus épais sur la photo joint.Vous n ‘avez donc plus besoin de mettre le double face qui maintient la batterie sinon vous ne pouvez plus refermer le boîtier et risque de ne pas être en face du trou pour connecter le câble de chargement. En tous cas la batterie charge reste à voir la durée de la tenue de charge . Je reviendrai après avoir fait plusieurs charge de la batterie .

bon
