Can seemingly dead, sulfated batteries be revived?
The answer is, sometimes. If batteries are sulfated for example, from sitting dead or from poor charging habits fully charging them, then using them for 5 charge/use cycles can sometimes remove much of the sulfations, restoring substantial battery performance. To do this, fully recharge the batteries, which may take much longer than normal, then use the batteries, depleting them then repeat the cycle 5 times. This process of charge/discharge can remove sulfation, restoring the batteries’ performance if they’re not critically damaged. Where can replacement batteries be purchased? Deep-cycle batteries for power wheelchairs are not only available through mobility providers, but also from retailers who sell a wide range of batteries. Some retailers have cross-references for deep-cycle battery applications specific to mobility devices, while others label deep-cycle batteries as RV/Marine (it is important not to confuse RV/Marine deep-cycle batteries with marine starting batteries if the mar
