August 15, 201114 yr Hi I have a Batribike Granite LCD which uses a 36v 10ah battery The charger is 36v 2a which only takes just over 2hrs too charge the battery from flat Is this right nookey
August 16, 201114 yr No, on a 2a charger it should be taking well over 4 hours to fully charge from flat. Either the battery is coming to the end of its life, and losing capacity or there is an issue with the charger causing it to stop charging too early. Have you got a multimeter to measure the battery voltage with? If so charge the battery and post back saying what the voltage reading is from the connector pins on the battery. Should be around 41-42v fully charged, and around 34v empty.
August 16, 201114 yr Author Bike is new Hi The bike is only 7 weeks old from new Only 2 hours to charge the battery from the first day i had it I have just got a new battery from take charge bike and batribike This unit is only taking 2.5 hours too charge from flat I think the charger maybe duff What do you think
August 16, 201114 yr How many miles can the bike do on one charge? I had a problem with charger a while ago, it was cutting out too early. I had to keep turning it off and on to get it charging. If you could measure the battery output after a full charge it would be easier to work out if the charger is faulty. Can you get access to another charger to try?
August 17, 201114 yr Author Hi Old battery was around 10 miles New battery dont know as yet not had a chance to test it I will test both batts with a multi meter What should they read fully charged Maybe i can get take charge bike to get me a new charger from batribike nookey
August 17, 201114 yr Yes, that is correct. It might be slightly higher when it comes straight off the charger, it drops after the battery has been standing for a while.
