FEATURES
Maintenance Free
The AGM battery adopts a sealed valve-controlled design, and the gas generated by the internal water splitting can be recombined back into the electrolyte during the discharge process, without the need for regular replenishment of the electrolyte. This makes it safe and reduces labor costs required for maintenance.
No Leakage
The internal electrolyte is absorbed by the separator of the AGM battery, and even if the battery case is ruptured, the electrolyte will not leak out easily.
Low Risk of Internal Short Circuits
Due to the extremely small voids of AGM battery materials and good puncture resistance, it is difficult for small particles generated by the aging of battery plates to pass through, eliminating the risk of internal short circuits.
High Output Current
The separator of AGM batteries has many pores filled with electrolyte, resulting in the largest contact area between the plates and the electrolyte, which can generate high instantaneous current. AGM batteries have minimal internal resistance, which allows them to deliver sufficient power pulses when necessary.
Excellent Deep Cycle Performance of AGM Batteries
The lead-calcium alloy electrode plate has mature technology and good deep cycle discharge performance. The surface of the plate is not easy to peel off, and it is not easy to crystallize sulfate, thus ensuring a longer cycle life.

NOTES
1. Due to self-discharge characteristics of lead-acid battery technologies, batteries should be top charged within 6 months of storage to ensure optimum performance, prevent sulphation and permanent capacity loss.
2. Charge profile recommendations correspond to battery voltages at 25°C (77°F). For temperatures below, adjust +5mVPC/°C (+3mVPC/°F). Temperatures above, adjust -5mVPC/°C (-3mVPC/°F). Temperature compensated charging helps ensure optimum battery runtime and life performance.
3. Charge profile recommendations depend on application and charger. IUI (or IUI with Pulse) is appropriate for applications that require frequent and deep discharges. IUU is appropriate for applications that are on standby and cycled less frequently.
4. IUI with Pulse algorithm uses a pulse termination criterion. The finish current is pulsed on and off in order to keep the battery voltage at a minimum while still reaching target overcharge. If average VPC exceeds U2 and the charger output has been on for more than 30 seconds, the output is shut off until VPC falls to U3.
5. IUI Charge Profile (if applicable), may have a continuous float phase added (2.27VPC).
