  1. Ever since I had a battery failure on the 2017 Trans Baviaans the topic of bicycle lights started to interest me. An electrical engineer by trade - I figured that this cannot be as complicated and expensive as the market seems to suggest. Over the last 4 years (on and off) I have tested the good, the cheap and the ugly when it comes to batteries for endurance riding. My findings have led me to build my own prototype and yesterday I finally came to testing it with known parameters. For the first test, I have used the Extreme Lights Endurance light which seems to be most used light for the rides that I have mentioned above. My test setup includes a GoPro with sequence shooting at 60 second intervals within clear view of my G-Shock which was used for timing. Extreme Lights claim 40+ hours' run time at the 200 Lumen setting when used with their 5200mAh battery - I am using the same Lumen setting but my battery is designed to produce 6800mAh at the same voltage. My test is 24 hours in and things are looking good thus far - I will keep posting on this thread for anyone that is interested. After the test is completed I will share some findings which may or may not be informative/trivial.
  2. Hi, My Garmin 920xt battery life is shot. The device can be opened with a hex screwdriver. Would be interested in hearing from anyone that’s changed a Garmin battery themselves. Has anyone attempted a battery change, and if so, which battery did you buy (see below) and from where? Do Garmin sell the batteries and if so for how much? I’ve looked at YouTube videos and there are a few that have changed the battery, which is attached to the back casing. Can import the battery with the casing -cost is under USD15 but the shipping is USD99, if anyone interested in a group order to bring pricing down let me know. Takealot has 920xt batteries for about R400, but (1) the connection is different to the ones shown in the YouTube videos and the ones that come with the back cover, (2) they don’t include the back cover, and (3) a video by Triathlon Taren indicates that the battery that’s attached to the back cover is malleable and can’t be removed from the cover easily. Has anyone bought these batteries from Takealot and how easy was it to change?
  3. Thought I would create this thread for those with a little more knowledge about cars to help us that are not up to scratch with what is normal and not normal. My first issue: My battery in my Honda accord was installed in September 2014 and its already dead as a door nail and not holding charge. Is this normal? Also what my discovery tracker device I had tested is pulling ampage when the car is off, I have requested this to be removed. Please feel free to ask any car maintenance questions and stuff here.
