100Ah 12V Photonic Universe Gel deep cycle battery for a motorhome, caravan, camper, boat, yacht, solar or wind power system, UPS, emergency and off-grid/back up power systems

THIS ONLY REVIEWS THE QUALITY OF SERVICE AND THE BATTERY AS NEW. The battery was given a top-up charge at the 14.0 volts required by this type of battery. Using an ordinary car battery charger is not recommended as it would likely shorten the service life of a gel battery, as "wet" car starter batteries and leisure batteries need to be charged to 14.45 volts. The battery required very little charge, and performed very well on my battery capacity tester. This tells me that this new battery is in excellent shape. I will find out whether the battery is worth the money in 5 or 6 years' time. I've had gel batteries last up to 14 or 15 years. The battery was well packed and arrived quickly.

We've got two installed in our motorhome, plus our leisure battery these are charged with 3 solar panels - absolutely fantastic so far, no problems, holding charge and provide plenty power. Well worth the little bit extra to get a good cycle life as well. At this time, I would certainly recommend these.

Purchased mine for a solar generator project, having just returned from a fishing trip I can now comment, Battery is quite heavy at thirty kg as you would expect from gel battery .. however it worked well I had a cooler plugged in pretty much all day as temps were 30°c + all weekend ..drawing 4 amps With sporadic charges of phones tablets etc Putting in about 6.2amps using 100w solar panel the discharge rate was as stated however my starting voltage was 13.5v dc I finished with about 12.4v due to a progressive over spend on use over 3 days .. this isn't a flaw with the battery however more the system ..i need more going in Looking forward to giving long term review hence 4 stars not 5 .. Delivery was as estimated..

Changed the settings on charger and solar charger to sealed /gel. Keeps topped up at 14.2/3 gives plenty of power and works well with solar panel. Very happy with this battery.

Although I have not had the time to give it a full discharge/charge cycle I can say that it arrived fully charged and ready for use. It is very well made and I expect it to give many years of service.

was given one of these with my van so bought 2 more ... wish id bought 3 but i usually have power left in them the morning so i manage ok ..would definitely buy again

From ordering to delivery the service was prompt and efficient. We used the battery during a 15 day camping holiday during August. To supply our power needs we connected a 12v to 240v inverter, which enabled us to charge all our mobile phones/ iPads and other electronic gadgets. The battery stood up well and for the first time we didn't need to top up the battery via mains at the local farm. On our return home I check the remaining capicity and was surprised to see only 25% of the charge had been used. Therefore I have been impressed by the battery on its first run out and would recommend it to others.

The internal resistance was a bit hi the other batteries I have. But I have put a 100 amps for 10 min that Voltage stayed at 12 volts constants. I tried a battery tester and it told me to replace it but it did run my devices adequately so I would recommend it I bought 2 of these batteries and thinking of buying a third.
