Many factors come into play when deciding often to charge the batteries.
If you use your product on a daily basis, charge the batteries as soon as you’re finished using your product to be ready each morning to give you a full day of use. It is recommended that you charge your batteries 8-14 hours after daily use.
If you use your scooter infrequently (once a week or less), you should charge the batteries at least once per week for 12-14 hours.
We unfortunately wouldn't be able to advise the usage of any batteries other than those supplied by Pride.
Please refer to the basic troubleshooting page in the user manual supplied with your scooter.
Please note that as the manufacture, we are unable to supply wiring diagrams to the general public, we can only suggest that you contact your chosen Pride Provider who will be able to assist you further with your query.
