I purchased a replacement battery (VP2200) for my MXi safe. The battery only lasts for around 6 days before being drained so low that the safe is inoperable unless I plug it into an outlet. If I had known the battery was that undersized for this safes application then I would have never wasted the money buying this battery. The site should say this battery will only hold charge for a week. Vaultek’s customer service replied that this is normal for this model battery. Plus, the Vaultek website shows that my purchase should have been a VP3000 battery. They suggested I spend even more money to purchase a VP6000. No thanks. As the saying goes “Fool me once…” Customer Service Rep said the website hasn’t been updated to reflect that the VP3000 is no longer available. I have two Vaultek safes but I’m seriously considering changing my gun storage devices. FOLLOW-UP TO REVIEW Sept 20, 2023 As expected, Vaultek Customer Service has not followed up with their e-mail promise to reach out to me for resolution of my poor experience with their battery’s performance. The takeaway is that they sure don’t mind taking your money, but when it comes to standing behind their products, they give public lip service then quickly disappear. Vaultek, please don’t send out another hollow response to make prospective buyers believe you have real customer service. Just be real and stop posing as a supportive company and show what you’ve become…a one time sale company with no customer service.
