Pendleton Sommersby Batter and Charger

[jayabrian]

I bought a Pendleton Sommersby step-through for my partner. Due to illness is wasn't used for a good few months. I will take the criticism that I should have regularly charged it or disconnected the battery, but we had more pressing things to worry about like major surgery!

When going to charge the battery, it appears completely dead. I am aware this is a known issue, but there is no response other than when I first plugged it in on the bike there was a little light up of the charge status LED then nothing. I have read that the battery can reverse polarise when dormant etc. At the moment the battery and charger have been in Halfords for 9 months. I actually thought they could just plug in another charger and check if it was the charger or a dead battery. Apparently this was too difficult without bringing in the whole of the Halfords repair infrastructure and nothing in fact has been done apart from the fact that the charger has been there so long they have PAT Tested it. Thanks for that at least Halfords.

So if anyone has experience of this particular model some questions if that is OK.

1. With the charger plugged into the mains, but not into the battery do you get an LED (green or red) on the charger.
2. If the answer to Q1 is no, then does that change when the DIN plug is inserted into the battery (off the bike)
3. Does anyone know the Pin out assignments on the DIN Plug so I can stick my Fluke on it and see if it is kicking out the required voltage regardless of LED Status

The fuse in the plug is OK I am seeing nothing on the battery LED charging indicators at all.

4. Anyone got any ideas other than pay 300 quid for a replacement battery and 30 quid for a charger

In 12 years of working with ebikes and being on this forum, I've never heatd of an ebike battery reverse polarising, so you can forget that.

Those batteries have a sleep mode that they go into when you don't use for a while. The wake up procedure is written in the manual. It's a legal requirement that the seller provides you with the manual when you buy the bike. Report them to trading standards if they didn't do that.

Here is the manual. Look at page 9.

It's probable that your battery has another problem, but you need to eliminate the obvious first.

....... on the DIN Plug.........

Hi I am just wondering if your bike has the newer or older version of battery and charger.
The older version has a charger with a 5 pin din type connector Model number SSLC084V42.. and the battery/charger connections are as shown in photo's below.
It would be helpful to know which version you have.

1. With the charger plugged into the mains, but not into the battery do you get an LED (green or red) on the charger.

I can't speak for the Pendleton specifically, but in general terms the charger LED is normally GREEN when only plugged into the mains.

2. If the answer to Q1 is no, then does that change when the DIN plug is inserted into the battery (off the bike)

On plugging into the battery (with the charger powered from the mains) the LED goes RED when the charger starts to charge the battery.

As I said, that's a general case although from my days when I did own an E-Pendleton, I seemed to remember that that was the case.
