## Description

Gel battery is a battery filled with a special gel-type electrolyte. Gel batteries are non-spillable, completely sealed and maintenance free - one of the safest batteries you can find. They have a much longer service life compared to standard wet-cell batteries due to lower degradation and internal corrosion. Gel batteries hold their charge very well and have a much lower self-discharge rate. Other important benefits of gel batteries include: - Better recovery from deep discharge - Wider working temperature range (gel batteries work well even in cold temperatures as low as -10C) - Their position does not have to be upright all the time - These batteries have better resistance to shock and vibration Deep cycle means that this battery has been specially designed for applications which involve regular deep discharge. For example, for use as a leisure battery in caravans, motorhomes, campervans and boats, or for energy storage in lighting systems, telecommunications, networking and off-grid power systems. This battery is also great for emergency power storage and UPS systems. This battery is perfect for Photonic Universe solar charging kits due to its excellent solar charge acceptance. It's also great for various wind power systems or for combined solar and wind energy storage. The service life of this battery is more than 5 years, but if treated well the battery can last up to 10 years. Battery specifications: - Nominal voltage: 12V - Nominal capacity: 100Ah (10h rate) / 108Ah (20h rate) - Maximum charging current: 20A - Self-discharge rate: less than 1% per month - Cycle lifetime at 30% D.O.D.: 1200-1300 - Pressure control: safety valve installed - Terminal type: F13 - Operating temperature: from -10C to +50C - Size: 331 x 173 x 217 mm - Weight: 30.3 kg The battery is packaged in a carton box with a user manual and bolts/washers for terminals.

Review: QUALITY BATTERY - 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.
Review: Great Batteries - 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.

## Questions & Answers

**Q: How many cycles under normal operation would one expect?**
A: Hello,

Thank you for your interest in our 100Ah deep cycle batteries. This Gel battery has a cycle lifetime at 30% D.O.D.: 1200-1300. The service life of the battery is more than 5 years and if treated well may last even up to 10 years.

The cycle lifetime will vary based on the depth of discharge, naturally. The deeper you discharge your battery the less cycles overall you will be able to run the batteries through in their lifetime.

Kind regards,

**Q: I need 4 gel batterie 12v minimum 100 ah each for my estrima birò,electric mopped. it previously had 4x12v 100ah genesis gel batteries. would it work?**
A: These batteries are really quite heavy (listed as 31Kg each) so four of them would weight a lot (I guess more than the weight of an adult) - You would need to be sure you have the space and the weight carrying capacity to consider using them.

**Q: Does this come with the cables i need to connect the battery to the control unit? If not, what cables / connectors do i need?**
A: It did not come with cables

**Q: I have to replace the batteries on my golf buggy. It is a single seater but quite heavy with my 13.5 stone on top! Can anybody advise plea se?**
A: 120£ ok

### ⭐⭐⭐⭐ Does what it says on the tin ,
*by G***1 on 2 July 2018*

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..
