I am curious to what extent small 12V lead-acid Gel-Cell batteries are used by the ham community these days. I am aware that in some areas they are used for extended run time on handhelds and they are included in what are called grab-and-go kits. At one time the 7AH was a common size to use.
A Gel battery or Gel cell battery is a type of maintenance-free sealed battery containing gelled electrolyteGel batteries are leak-proof offer low self-discharge 1-3 per month long life in cycle and excellent resistance to shocks. Gel batteries are designed to withstand long deep discharges making them the number one choice for small mobility and traction applications. For all Gel-Cell batteries ranging from less than 5 ampere hours to over 400 there is a charger here to meet your needs.

1 - Lead acid batteries have been around a lot longer and have caps so you have to unscrew them to top up using de-ionised water. 2 - An AGM battery is completely sealed and maintenance free while generally giving you more recharging cycles which means it will last longer. 3 - GEL batteries are completely sealed and maintenance free this means.
A sealed battery is NOT necessarily a gel type. Right but you can tell a lot by the voltage across the cell while its trickle charging. Gel cells starved lead acid cells and regular lead acid cells all share the same chemistry and will show 2-24 volts per cell NiCads and NiMH are 12-14V and Lithium cells run about 3V.
Similar to AGM batteries the number of cycles decrease as you further discharge a gel battery. For example discharging a gel battery at 30 gives you about 2600 cycles compared with only 1200 cycles with AGM batteries. In fact if you discharge a gel battery to 90 it will give 700 cycles which is more cycles than an AGM battery.
SLA Batteries cover so many applications here are but some.

A gel cell battery is a popular choice for motorized wheelchairs RVs golf carts and marine applications. Simple 12 volt gel cell battery charger circuit constructed by using few easily available components.
This circuit can charge gel cell battery with reverse current and overcharging protection. We know a Gel cell battery is a VRLA valve regulated lead-acid battery with a gelified electrolyte and this type of batteries are maintenance free batteries. Hi does anyone have any linkscircuits for a gel cell charger that will take a 12V input from a vehicle battery to charge a smaller 12V battery.
I saw one in a distant issue of Silicon Chip magazine but I dont think thats available anymore. Or can I just connect the gel cell to something like a cigarette lighter. If you are buying used Gel Cell batteries at a flea market for example be sure to have your digital voltmeter with you and a load such as a small automotive 12V light bulb.
After a gel cell battery has been removed from the charger the terminal voltage will gradually decrease to a. Renogy Deep Cycle Pure Gel Battery 12V 100Ah. The heavy-duty lead-calcium grids within this battery are meant to last up to 10 years and the PE compound separator design distributes gel electrolyte evenly through the batterys interior meaning maximum consistency in output.
Whats amazing about this GEL model is that compared to the. Complete 3-step charging program Qualification Bulk Charge Float Mode 3500. Quick connect harness included for hard to reach areas.
Charge and maintain any type of lead acid battery - AGM absorbed glass. Generally gel cell batteries last longer than sealed lead acid batteries as they resist sulfation. Charging a gel battery with a lead acid charger is risky since gel batteries require constant voltage charging versus taper charging provided with lead acid chargers.
It can be done if you monitor the charging process closely. Commodore Australia Gel batteries or gel cells contains acid that has been gelled by the addition of silica gel turning the acid into a solid mass that looks like gooey Jell-O. They contain less acid than a regular battery and there are several advantages to using gel batteries.
Maintenance Free They are maintenance free. Since the battery system is designed to eliminate the emission. For my first non-trivial arduino project I am trying to make a solar powered arduino duemilanove.
For that I will use a 12V 7Ah gel cell battery. For properly charging the battery on standby with the solar panel it needs a constant voltage supply of 137 to 139 volts at 20 C with a temperature compensation of -20mVC. At least that is what the specification.
