This battery is rated to last 200-250 cycles (load shedding).

During occasional load shedding, at stage 1-3, the average life span is 2 years.

Unfortunately, during constant load shedding, at stage 4 - 6, these cycles will be depleted within a few months. 

The batteries will also be further degraded due to insufficient time to recharge fully in between load shedding cycles.

**Please note that as soon as the battery stops lasting, unfortunately the warranty becomes void, as this means that the battery has depleted its cycles and reached the end of its life.

Therefore, during stage 4-6, if using in conjunction with an inverter, we highly recommend turning off the power switch on the inverter itself, when the need for power is not crucial.

This will preserve the longevity of the battery (please keep the inverter plugged in to the wall permanently to keep it charged).

*Please note - delivery will take 1-2 days extra to any area outside of Gauteng

*Please note - an additional charge of R295 shipping applies owing to the weight of the battery

*Collection from our Joburg office will be at no additional charge

The Enertec (105AH – 12V) DEEP CYCLE Maintenance Free Batteries.


These batteries are designed for backup/marine use only - not for daily SOLAR OFF-GRID charging/discharging

- Enertec Deep Cyle batteries never need water. Antimony-free plates cut electrolyte loss from gassing. Special liquid-gas separator keeps electrolyte inside.

- No filler caps - so no electrolyte contamination, overwatering or damage in use.

- Unique wrought lead-calcium grid design means less internal corrosion and efficient current conductivity for more power and longer life.

- It also cuts gassing, resists overcharge, heat and thermal runaway.
- Generous electrolyte reserve, factory checked for purity and specific gravity, is sealed in to last the service life of the battery.

  • Asked by Vicky
    Will this battery be suitable for the Mecer 1200VA 720W 12V Inverter? We only need to run 2 PC's and a Printer Answer:
    Yes, it would be. It is what we ourselves recommend for that inverter
  • Asked by Kobus Boshoff
    I have a 5 kw Mecer/Axpert Inverter, 9 x 250 watt solar panels and 4 x 200 Ah Gel Batteries. The inverter is also connected to Eskom grid. 2 Of the 4 bateries collapsed within a few months. Now I was told that my inverter is not compatable to Gel batteries. The inverter does not provide the neccecary charge to load the batteries and the result is that the batteries collapse. Can you please give me advice. Answer:
    You need to check the recommended charge voltages for the batteries. You can then set the different charge voltages on the Mecer unit
  • Asked by a guest
    How do you determine if the battery meets its A/H rating? Eg. what load do you use (ie current) whilst monitoring the discharge period (time) that the battery can supply this test load,current. Answer:
    Batteries are rated over a 20 hour period. So you would need to run a 5Ax12V load for 20 hours = 60W for 20 hours. However, that will take the battery to 0%. So to be safe, run it for 10 hours and you should get to 50% SoC (around 11V)
  • Asked by Rod Harman
    The red light was showing indicating less thsn 50% charge. I charged for 48 hours and the red light was still showing but the voltage read 16.what must i do? Answer:
    Nothing - it just needs to equalize for the indicator to go green - this takes a few days to change colour. A small shake of the battery can also help
