First and most important, it is not safe to charge a battery with higher-than-specified current. Doing so risks damaging the battery (at best) and causing a fire or explosion (at worst). Fortunately, what you are asking about is not the charging current, but the current available from the power supply that supports the charger.
This means that you need to find other ways to keep yourself safe. You should never let a positive and a negative connection touch when working with batteries, especially at high voltages. Electrical tape, heat shrink tubing, and even 3D printed caps can all serve this purpose. You need to make sure that they have a secure fit. 6.
No battery is able to maintain a perfectly constant voltage. The more potential energy stored in a battery, the higher its voltage. Alongside this, though, having a lot of potential energy will make leaks, explosions, and shocks more powerful. Manufacturers provide a safe storage voltage for their batteries in their documentation.
Over the last several years and for the foreseeable future, the use of lithium-ion (Li-ion) batteries to support UPS systems continues to increase. Again, the electrical danger of removing the input transformer would be the same as lead-acid batteries.
