I looked into this a bit more. i was curious as on the website for this scooter, the company quotes up to 20mile range, but with no other information as to what D0D for the battery. So after calling their tech department, I was informed that that figure pertains to doing a near 100% DoD on the...

So I did a bit of a follow-up, and did another 6 laps 2days later (without recharging), and the results were interesting: Initial voltage after recovering for 2 days was 12.78v Lap 1: 12.54 Lap 2: 12.5 Lap 3: 12.44 Lap 4: 12. 41 Lap5: 12.36 Lap 6: 12.29 So there was a steeper drop off for the...

Ok, I did a 3 mile test. I did 6 laps on a half mile circuit and did a reading on each lap: It wasn't all on the flat, but as it was a circuit it had equal uphill and downhill. Lap 1: 12.74 Lap 2: 12.72 Lap 3: 12.69 Lap 4: 12.65 Lap 5: 12.61 Lap 6: 12.61 After all these laps I did a voltage...

After a short recovery time: New Batteries 13.11v 13.16 Old 12.96v 12.97v So both recovering, old just a bit slower than new. But, do those readings suggest both batteries are performing well for deep cycle? Or should I be using another way to assess them?

OK...the results, and they are....interesting to say the least. I took the caddy covers off and measured voltages on each battery directly with the scooter moving. I had to hold it while moving but I think I got stable enough readings. I would like some opinions on initial interpretation...

I guess I can run the caddies without the lids. I would then see the voltage drop across each battery when used, and what, it should not drop below 12.4? Something like that?

Any thoughts of the best points to test these batteries, and to assess their condition. Is the voltage drop when the scooter moves due to the fact they are in series or something. Just trying to get my head round why the reading would drop to 0. The multimeter I am using is a decent one, so...

I located the only points I can see coming directly from the two battery caddies, there is a junction where two positive and two negatives meet a connection bridge where the rear of the scooter detaches (it's collapsible). I get a voltage reading when connecting the multimeter to one of the...

As a small follow-up from my earlier post, I finally managed to do a motorway only fuel check. It was a petrol station start and finish journey of 250miles. The journey unfortunately featured quite a few delays there and back, with a lot of slow crawl traffic at times. The trip computer came...

I took all those readings from the the three prong charging port on the scooter itself. In this case, it is situated on the neck of the tiller. In the days that have followed, from only a rough estimation, it seems these batteries have struggled to provide more than 5miles or so before starting...

OK, i bit the bullet and bought some new Yuasa's The scooter is not used enough to warrant lithium or all the additional considerations and costs that involves. Scooter is a TGA Zest Plus 4mph scooter. (Great scooter by the way) So i went for the 36ah AGM Yuasa I received them and did a...

How many miles do you do in a year? I think that car with 16 year old tyres on had done 30k, and there was still deep tread on the tyres :LOL: There are some tyre brands that have compounds that last longer. Also while a lot of tyres start with 6mm tread, you can get ones that start with 8mm...

Agreed, it's really important not to ignore tyre issues. A relative bought a used car. I reminded them to check the tyres before purchase but, in their excitement, they forgot. The car was 16 years old, and still had two tyres on it that were original to the car. The youngest pair were still...

I am never sure how to interpret Citroen's loading pressure. Normal loading is fine, but I find their "full load" hard to interpret. Ford often stipulate 3+ and luggage etc. But I'm never sure if this implies being closer to the max carrying weight of the car, rather then "3+ in the back...

It was essentially one of these, but on a gantry

Well, it happened again! Travelling up the M1, and the gantry indicated that the outside three lanes were closing. As I was already travelling in the inside most lane already, I initially ended up in the inevitable queue. But after rechecking the signs, I realised that all the other lanes...

In all previous instances, when a fuse has popped, the DNO has been contacted, they turn up and swap the fuse. As I mentioned it has happened about 3 or 4 times over a 4/5 year period No, they have not charged for the visits, nor advised about covering any costs of replacing the fuses. They...

I am a friend of the building owner. They have had this ongoing puzzling issue for 5 years. This time they were away when it popped and I helped out by going there to let the DNO in to replace the fuse and witnessed it all. So knowing about the knowledge base here I thought it would be a good...

Assuming I monitor as per above to see if anything can be gleaned. Is there still the potential that there is some kind of damage on the supply side which could be causing this?

It's happened maybe three or four times, at random, in the past 4-5 years. Twice on the flat side ( I think), and maybe twice on the 3 phase side, a different fuse each time on the three phase side.
