Proper procedure to take batteries out to recharge them or replace them

Any battery that is found to be low in charge or completely discharged needs attention; testing should be performed to find out state of charge and the ability to sustain a load. I do not see a need to remove either battery; I would suggest either and both may be charged by removing the battery cables and attaching charger cables. You may find that any battery left discharged for weeks may not be able to be recharged to a useful level. This is why testing following charging is essential. https://repairpal.com/auto-repair-near-me Click the link or call us at 877-913-1554. We'll gladly find you a certified RepairPal shop in your area.
