2.5 Batteries
Working in the vicinity of a Lead-Acid battery is dangerous. Batteries generate explosive
gases during normal operation. For this reason, it is of utmost importance that you
follow the instructions each time you use the charger.
Only use the Battery Charger for charging Standard Automotive Lead Acid, Calcium
Content, GEL, AGM, SLI, Deep Cycle or Lithium Iron Phosphate type 12V batteries.
When charging a battery, ensure settings at the Battery Setup menu on the Remote Monitor
are correct for the type of battery under charge. Charging a battery with the wrong profile
may cause The Manager30 to indicate a fault or give misleading results and could result
in damage to the battery. Noticeable oscillations between Boost and Absorption stages
indicate incorrect choice of battery type. Check and adjust battery type. If you are unsure
of the battery type or settings to use, set The Manager30 to the Gel profile.
Figure 2.5.1 and 2.5.2 show standard wiring for batteries in series and parallel respectively.

To ensure that all batteries are equally charged, loads and The Manager30 should be
connected with ground and 12V power connected diagonally opposite across all batteries
as shown in Figure 2.5.2.
The Ah rating needs to be setup when prompted on first start up (Refer Section 3.3), these
settings can also be modified in the “Advanced Settings” menu (Refer Section 3.5). To
calculate Ah rating of batteries in parallel simply add the rating of each battery in the bank
together. For example, 3 batteries with an Ah rating of 100Ah each will yield a total of 3
x 100Ah or 300Ah. Batteries connected in series will assume the lowest Ah rating of the
batteries in the bank. For example, 2 batteries in the bank, one is 50Ah the other 100Ah.
When connected in series the Ah rating is 50Ah.
