VDC 3.7v 1150mAh 102540 Oplaadbare Polymer Lithium Batterij voor Sena 50S Motorfietsen Bluetooth Headset Batterij Vervanging Intercom Batterij Vervanging

De batterij zal wel prima zijn, maar de dikte is geen 8 mm volgens de beschrijving, maar 10 mm, en nu past het niet in mijn behuizing, jammer.

Sena 50SWorks but you gotta monkey around with it to get it to reasonable.

Der Akku konnte ohne Probleme mit dem originalen Akku getauscht werden. Nach dem Tausch war die Laufzeit wieder wie zu Beginn.

Mi è piaciuto il prezzo , ma non è specifica per il sena SF4 . Ciao

Produit nickel fonctionne très bien. Installés depuis un mois et tout va très bien

Rating the battery life and value for the money would take six stars. Easy to install? Maybe not so much in a 50S.After three seasons, the last with little or no runtime, it was like getting a new radio. Then after a few weeks of LD riding, the (four so far) batteries I've replaced for family and friends are still going strong, on mesh, noise cancelling, bt Garmin + audio stream to some decent HK speakers, occasional incoming phone calls... all, day, long.It needs to be made simpler to replace batteries like these. They work very hard through hundreds of all-weather cycles. The lifespan of batteries like these should not be expected to determine the life span of pricey devices. Not sure I would recommend this job to someone unfamiliar with this kind of DIY repair, or with unsteady hands. I paused a YT video each step my first two replacements - and I am familiar with this sort of thing. The 50S needs to be opened carefully and reassembled correctly. There is little or no wiggle space for wires, the gasket, edges of the battery, etc.I since found a $10 USD "phone repair" tool kit with plastic and metal pry tools, tweezers, handy screwdrivers and other things all in one zippered pouch that make this type of repair much-much easier. Adequate light and clear focus or magnification also.*I believe the 50S new is sold as weather resistant and mine have delivered that much. Opening the radio you'll see small dots of clear sealant over the recessed screw heads, the gasket you'll see around the perimeter seam, and a few other places Sena saw fit to use sealant. Putting the radio back together without resealing will make your 50S less weather resistant.I try to use a moderate output charger (that 1A white cube) on Sena's Wi-Fi cable, then not leave everything plugged in after the red LED turns blue. These are a relatively small capacity class of battery. Not much gain trying to use a higher output quick charger. The 50S is apparently calibrated to show 100% at 1000mAh, so don't be surprised to see ~110% battery level in the Sena phone app. ;-)
