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.
When charging a battery, make sure the 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 the wrong 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 setting.
Figure 2.5.1 and 2.5.2 show standard wiring for batteries in series and parallel
respectively.
Figure 2.5.1 - Batteries in Series.
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.
