AGM battery 12 V / 9 Ah — Long

The largest real reserve we carry for the scale — 7.5 Ah under slow discharge. The choice when you want the scale to run as long as possible without a visit.

Why an AGM battery for the scale

The scale runs on 12 V and the battery is its only power source — there is rarely mains power at an apiary. That makes the battery type worth thinking about. AGM means the electrolyte is absorbed into a glass mat rather than sitting free as in a conventional battery. In practice:

• It cannot leak or evaporate — it can lie on its side or sit at an angle
• It needs no maintenance — no topping up with distilled water
• It stands up to vibration better — which matters when you move hives
• It self-discharges more slowly — so it lasts longer while the scale sits idle over winter

How long one charge lasts

That depends on the measuring interval and the strength of the GSM signal. At the factory setting of 60 minutes, a healthy battery comfortably carries the scale through a season. Where the signal is weak the module transmits at higher power and draws more, so a larger capacity is worth having.

Charging

Charge it with a charger intended for lead-acid batteries — ideally one with a maintenance stage, which tops the battery up without overcharging it. We carry two suitable chargers in the shop.
