how do i know if my razor motor scooter's battery is dead?
I have had it for at least 3 or 4 years. It has been through cold winters and has been used a lot. It has accidentally stayed on for a week once.
Also, whenever i plug it in 2 charge, it says the battery is full??
HELP
Take the battery out and have it tested at an auto shop. Needs to be tested under load. 4 years is quite god for this type of battery.
Chances are the battery lost most of its life , you can hydrometer it if possible or check voltage.
batteries dont last forever technically every time its charged it looses a tiny tiny bit of strength in the end all rechargeable batteries have to be changed 4 years is pretty good i’d say and if it says its charged though even when dead it could be the charger though i still say that the battery may not hold a charge anymore i’d check all connections make sure they are clean and solid after that id charge it for a day or two just to see if its working then after words id start buying some stuff
